A Comedy of Errors - Printrboard Rev F5 Firmware Editing How-To

Preface: I am writing this after the fact, and narrating events as they happened to me. I will (somewhat shamefully) admit that this took me about a day and a half to figure out. Hopefully it helps someone figure out how to do this, if I am correct it is a fairly niche problem as there is very little information for this specific board (rev F5). The process I went through to program the board starts several paragraphs down, feel free to skip around and control F, you will probably find something that is relevant to your particular situation.

As a gearhead, I am enthused by almost all things machines, and love to make. Naturally, I have a 3D printer (a Printrbot Simple Metal with heated bed from Dec. 2015).

It comes with a Ubis hotend. Over its life, it slowly became more and more averse to having filament pushed through it, and eventually rendered the printer slightly better than unusable. It was time for a change, as you can see...

Melted plastic had permanently cemented itself around the nozzle, rendering it hoopajooped. I had heard plenty about the E3D V6, so I got one and began the upgrade.

The build is fairly self explanatory, and E3D gives excellent instructions on how to do it. If you have the same Printrbot as me, be warned--the heater block WILL COLLIDE WITH THE BASE OF THE PRINTER IF YOU HOME X Y AND Z AND HAVE THE LONG SIDE OF THE BLOCK TOWARDS THE REAR OF THE PRINTER! And this WILL bend the heat brake--ask me how I know! If you scroll down you can see the orientation of the heater block that I ended up using.

With that done, it was time to modify the firmware so that the printer would recognize the new thermistor in the new hotend.

This is where things got dicey. There is almost no information on how to perform this modification with this exact board, the Printrboard rev F5. And if you’re like me (a somewhat boneheaded mechanical), this poses a great challenge. There are quite a few ways to perform these upgrades. If you just need to flash your firmware, you can use Atmel Flip to flash the Printrboard (I had done this before, there are a few guides on how to do this, such as this one https://printrbot.zendesk.com/hc/en-us/articles/202457834-How-to-Flash-Printrboard-Firmware). However, we don’t want to use a pre-baked firmware for this because we need to CHANGE the firmware. How the hell does one do that? This is about where I was at, and boy was I lost.

I had remembered watching a video by Thomas Sanladerer, an excellent YouTube content creator that makes informational videos about 3D printing. It shows the exact process of how to upgrade your firmware for a general 3D printing control board, such as a RAMPS or RAMBO board (Link: https://youtu.be/3gwWVFtdg-4). But I didn’t have one of those, so when I tried it, I uh... had some problems.

First, Tom recommends to use the Arduino IDE to flash the board. Now you might say, “This is a non problem! You can just tell the Marlin firmware to use the Printrboard Rev F in Configuration.h by specifying that it’s a printrboard and then hit upload. Easy!” Well, maybe for you, my microcontroller-familiar friend. Let me tell you a story of honest confusion, hunger induced frustration, and general disorientation as a hardcore mechanical tries to figure out how to do basic things with microcontrollers and C++ configuration files.

At first, I was confident. I had watched Tom’s video and thought that there was no way I could mess this up. And it would have been, if the Printrboard was based on the Arduino Mega like basically every other 3D printer control board. Haha, guess what, it doesn’t.

What the hell is that? And why is the Arduino IDE telling me that it doesn’t recognize a Printrboard when it’s one of the supported options? What does it mean Unknown CPU?

Later I would realize that these error messages were telling me exactly what I needed to do. But, in the moment, I was baffled and frustrated that it wasn’t working. More importantly, I was neck-deep in the names of different microcontrollers that were clearly reluctantly created by computer engineers who really didn’t care what the hell they called their new product, and just decided to use the seventh thing that came to their mind.

At this point I thought that the Arduino IDE was telling me that it couldn’t identify the printrboard. While it was true that it couldn’t identify the printrboard, it wasn’t telling me that. Nevertheless I soldiered on, and figured out that I needed to install another stupidly named piece of software (link https://www.pjrc.com/teensy/td_download.html). This let the IDE actually recognize the printrboard, and the fact that it doesn’t actually use an Atmega 328 processor, but an AT90USB1286.

So that was a revelation. At this point, for the first time in four hours, the IDE could actually see the damn board. Keep in mind that I still had made no progress on the actual errors that the IDE was spitting at me. So I set off there.

The compiler kept claiming that this was an “unknown board” and that it didn’t have the pins for the board. I didn’t understand since I had done exactly as it asked and put “BOARD_PRINTRBOARD_REVF” and that the board was explicity listed in pins.h. After trying the number of the board, 811, in exasperation, I finally read what the IDE was actually telling me, saying that it lacked an identifier. I don’t know what I expected, this being C++, but you have to not just #define 811, you have to #define MOTHERBOARD 811.

And now the momentum built (or so I thought). The verifier progress bar advanced a little bit more. Next it complained that it wanted the ”traditional marlin” pin layout instead of the “AT90USB1286.” So I looked in the pins_PRINTRBOARD_REVF.h, and once again actually read the error message, directing me to fastio.h and comment out _AT90USBxx_TEENSYPP_ASSIGNMENTS. Now I felt like I was on to something! Next was something about DAC stepper current. I am writing all of this after the fact, but it was somewhere, I think in configuration_adv.h. The change should be similar to the previous ones, but I’m not sure, it could be something else.

By the way, if you’re installing the E3D v6, the steps for modifying the firmware are well detailed in the installation manual you can find by googling “e3d v6 install.” These changes are much easier by comparison.

The verifier finally completed successfully, and with the board I was using recognized, I selected the USBtinyISP programmer in the “Tools” tab of the Arduino IDE and uploaded it to the board. I fired up the printer and to my amazement, it seemed to work. Seemed to work.

The hotend performed very well. I didn’t have much of a way to check if the temperature was correct (i.e., the firmware changes worked). I touched a piece of scrap PLA to the block at about 60c and it seemed to go into glass transition, and heated it up all the way to see if it would melt. It did, so it must have been in the ball park.

So I used the printer for a while until I was ready to try enabling mesh bed leveling (which isn’t even possible on a printrbot that doesn’t have an LCD screen). At this point i noticed the little teensy board programmer that keeped popping up saying that the “Marlin.ino.hex” file was too large. I had completely ignored this thing up until now, simply reading that the arduino IDE had “Uploaded Successfully” and assuming the teensy programmer was redundant.

...it wasn’t.

I had somehow figured out that most 3rd party AT90USB1286 programmers could only write 64 kilobytes of program to the chip, even though it has 128 kilobytes of memory. Why? I have absolutely no idea. Regardless, I remembered that I had used Atmel FLIP to install a new prefab printrbot firmware onto my printrboard a while back. You can find a link to that above in the first part of this post. So, I tried that, and it worked. I then went to test the unified bed leveling and the printer instantly crashed as I tried to raise the Z height and it crashed the print head into the bed. Sure enough, NONE OF THE PREVIOUS FIRMWARE CHANGES I HAD EVER MADE WORKED. NONE OF THEM AT ALL. So, suddenly, all of the changes I had progressively thought i had made happened at once, and all of the default settings in Marlin that were wrong showed up, and everything went to shit. But now I had completely figured out how to change firmware settings on my printrboard. And you too can figure it out if you read this... hopefully.

Something I repeated to myself a lot during this is that if you’re not making mistakes, you’re not learning. As you can see from this article, I learned a lot in the past few days. Here’s the hotend on the printer! It makes a huge difference. No more roasty Ubis for me.

Happy printing!

Email me if this doesn’t make any sense and I’ll try to help.

Editor's note: An earlier version of this story did not clearly indicate that the Makergear M2 won in the new Workhorse category with a 9.2 score. The story has been updated to more accurately reflect the 3D Hubs ratings.

Online user community 3D Hubs has published its third annual 3D Printer Guide for 2017, based on reviews from 8,624 verified 3D printer owners of 513 different 3D printer models.

Fourteen machines separated into five categories made it into the guide's top 3D printers list for 2017. The categories include Budget, Plug-N-Play, Prosumer, Workhorse and SLS or selective laser sintering machines, which is a new commercial-grade category.

3D Hubs used a wide range of parameters to measure the user experience with 3D printers, which included print quality, build quality, reliability, ease of use, print failure rate, customer service, community, running cost, software, and value.

In all, the guide rated 72 machines (half as many as last year), from a 1, the lowest ranking, to a 10, the highest. Only machines with five or more reviews were included in the Printer Guide, which left out 441 machines that were submitted for review.

3D Hubs is a three-year-old Amsterdam-based startup that created an online distributed network as a marketplace for printing 3D objects. The network quickly grew to include more than 10,000 3D printer owners throughout the world.

The ratings include the top 20 machines in five categories and 126 printers that didn't make the top cut in their categories.

This year's categories are different from last year, in that the "Enthusiast" category has been replaced with a "Prosumer" and a "Workhorse" category.

For the first two years the guide was published, the Makergear M2 (Amazon price) fused deposition modeling (FDM) printer took the top spot with a 9.1 rating in the "Enthusiast" category, which is for intermediate and professional users. This year, the Makergear M2 again took the top spot with an even higher rating -- 9.2 -- but in the new "Workhorse" category, which includes "robust machines that can print nonstop with minimal print failure."

"These are printers manufactured with reliability in mind and are open to slight modifications and tinkering" the Guide states.

In the Prosumer category, the Ultimaker 2+ (Amazon price) took the first place with a 9.1 rating.

Also included in the top three Prosumer machines category were Formlabs' Form 2 SLA stereolithography or resin polymer printer (vendor price), which received a 9.0 rating, and the Zortrax M200 (Amazon price) FDM printer with an 8.9 rating.

Three other machines with the top spots in the Workhorse category included Aleph Objects' LulzBot TAZ 6 (Amazon price) with a 9.1 rating; the BCN3D Sigma (Amazon price) with an 8.9 rating; and the FlashForge Creator Pro (Amazon price) with an 8.9 rating.

In the Budget category, which focuses on machines that offer good print quality as well as the best value and bang for your buck, top honors went to Prusa Research's Original Prusa i3 MK2 (vendor price), which garnered a 9.1 rating. The Prusia i3 comes as a kit, which means it requires more assembly than most. But it is also considered a RepRap-style machine -- meaning it can print its own system parts -- so it shouldn't be too difficult to put together.

The two other machines with the top Budget category rankings were the Rostock MAX (Amazon price) with an 8.8 rating; and the Printrbot Simple Metal (Amazon price) with an 8.5 rating.

In the Plug-N-Play category -- which as you might have guessed means you can pull the machine from the box, plug it in and start printing with little to no setup -- CraftUnique's CraftBot PLUS (Amazon price) grabbed a top spot with a 9.1 rating. Also receiving a 9.1 rating in the Plug-N-Play category was Aleph Objects' LulzBot Mini (Amazon price). The CEL Robox 3D printer (Amazon price) came in third with a still-high 9.0 rating.

In the new Selective Laser Sintering category, only one machine was reviewed -- the EOS P 396, an industrial machine that retails for $250,000. (Vendor site.) But, what do you expect to pay a floor-standing 3D printer that uses a laser to melt and solidify layers of powdered metals into finished objects? The EOS P 396 got an 8.2 rating based on the opinions of 50 owners.

New Post has been published on https://engineer.city/am-opportunities-in-the-wind-turbine-industry/

AM opportunities in the wind turbine industry

There are serious opportunities for Additive Manufacturing (AM) in the wind energy industry. Here, materials scientist Inês Castro from Matmatch outlines five key areas.

Additive manufacturing, also known as 3D printing is “the process of making parts from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing and formative manufacturing technologies” [1].

Contrasting with these latter technologies, AM can produce components with complex geometries, consume fewer raw-materials, produce less waste, have decreased energy consumption and reduced time-to-market. Adding numbers, AM can speed up the development time by up to 75%, reduce material resources by up to 65% and reduce gas emissions by up to 30% [2]. Moreover, a single part can be manufactured in one step, not requiring a secondary joining process [3,4].

Additionally, additive manufacturing doesn’t solely need to be applied to the early stage of development, but can also be incorporated in the repair of components. In the early stages of being introduced to the market, AM was used to create and develop models and prototypes. However, due to all of the advantages offered, the market for 3D printed products started to grow, especially in areas with short-run production and with high customisation and freedom of design [4].

There are several additive manufacturing processes and techniques that can be classified in terms of heat source, the feedstock and the manipulator [5]. The processes can be applicable to multiple types of material, including polymers, which are more common and developed, also composites, ceramics and metals [6].

Additive manufacturing applied to wind turbines

The Global Wind Energy Council has stated that the wind industry is experiencing exponential growth recently with the aid of the offshore wind turbines market. Thus, development and innovation through materials and manufacturing technologies are essential for the wind industry to prosper and to continue increasing its annual energy production [7]. The blades rotate and shift with the action of the wind, making the rotor spin. The gearbox makes the connection between the low-speed shaft to the high-speed shaft, increasing the rotations per minute from 30 to 60 rpm to approximately 1000 to 1800 rpm, in turn making it possible for the generator to produce electric power. The tower supports the turbine’s structure, with the nacelle containing and protecting the components on top of the tower [9].

AM technologies show a lot of potential when it comes to the wind power industry, as it could in the future enable in-situ manufacture of turbine components that are designed for the unique needs of the resources of a particular location. This would, for example, decrease the shipping, transportation and handling costs and increase the rate at which new blade prototypes can be tested[6].

Additive manufactured moulds

The Advanced Manufacturing Office (AMO) of the US Department of Energy has started to print moulds for the blades with AM technologies, as shown in figure 2. Consequently, it can make wind energy a more market competitive technology. The expansion of this application in the mould industry would reduce the steps, the cost and the time for mould fabrication, as the traditional route is a process that may take several weeks to months to achieve in its totality [6,10].

The mould in figure 2 was created by joining multiple printed sections created in the Big Area Additive Manufacturing (BAAM, figure 3) 3D printer at Oak Ridge National Laboratory [10].

The final blade section was successfully manufactured using the AM mould and can be seen in figure 4.

Additive manufacturing of small, off-grid turbines

A different project called ‘A Small Turbine to Make a Big Difference’ started by Kyle Bassett, has the goal to install small-scale plastic-based 3D printed wind turbines in remote areas with a lack of access to electricity. The founder of this project started by designing a turbine capable of storing the generated energy in batteries for personal use [11].

As a result, a scale model of the turbine (figure 5) was developed using a Printrbot Simple Metal 3D printer [12]. It included the blades, hubs, rotor connectors, the frame and the blade ends, which would be the most expensive components if made through traditional manufacturing methods [13].

Printed nacelles

Other applications could include the creation of the nacelle. The advantages of incorporating AM into such structures are similar, e.g. economic incentives for mould production, but challenges are also encountered, such as the need to offer weather protection, passive cooling and high geometry complexity.

The Additive Manufacturing Integrated Energy (AMIE) project, however, has successfully manufactured the nacelle structure and it can be seen in figure 6 [14].

Repair and replacement of components

Even though most of the attention is focused on the manufacture of new components, the repair of parts which need improvement or replacement due to wear should also be considered. For this application, hybrid systems incorporating processes such as Directed Energy Deposition with subtractive machining could eventually lead to the proper tolerances and design imitation of the replaced components [14].

Printing large-scale components

Large scale metal AM or wire and arc additive manufacture is an emerging technology which may facilitate the printing of large-scale parts. This even makes additive manufacturing of the nacelle and blade moulds possible, as it doesn’t need a constricted operation room, allowing as the name indicates, large-scale applications.

Overall, additive manufacturing technologies offer a wide range of advantages for the wind industry. The examples given show that implementation is possible, and even recommended, for a more market-competitive energy supplier. After the technologies became more developed, reliable and standardised, the supplier chains will be reduced and the production could be more localised, reducing the transportation times and costs, allowing the further implementation of AM in the wind industry.

Affordable 3D Printer Examples To Check Out in 2017

3D printing at home has become easier than ever before, and that’s because of the vast array of affordable 3D printers on the market.

You can now complete your projects without spending a fortune on special parts and costly prototypes – simply download a public 3D domain file for free, and apply an inexpensive filament, and the work will be done.

According to some statistics, cheap 3D printers are easier to use, and are thereof recommended to first-time users looking to enhance their startup project, or to teach some engineering fundamentals to younger audiences.

3D printer prices vary depending on the brand, but unlike the time it took $100,000 to purchase them, the cheapest 3D printer nowadays costs somewhere between $400 and $500. Looking for well-preserved 3D printers for sale may turn out to be an even more economical solution.

Fairly enough, you can’t expect a 3D printer for sale to have the bells and whistles of a professional one, so be ready to embrace the limitations imposed by lower 3D printer prices.

Your off-the-shelf printer may decrease build volume as it does not offer a heated print bed, neither will it guarantee the same quality as market’s frontrunners. The best cheap 3D printer, however, offers functionality that should not be neglected.

Plus, much of your work will depend on how creative you are, so if you work on projects with tinkering and patience, the 3D printer cost will not matter. In certain cases, you will even be able to create breathtaking projects at half of the price you paid for your new smartphone. Doesn’t that sound awesome?

But how much does a 3D printer cost? More importantly, which are the best 3D printers for sale that won’t break the bank? In order to answer these questions, you must define your needs and expectations, and compare several solutions to discover the right product for your projects.

I know you are looking for the best 3d printer under $500 or the best 3d printer under $1000. There’s a bit of something for everyone in this article that shows the best and most affordable 3D printers in 2017.

Dremel 3D40-01 Idea Builder

The Dremel 3D40 Idea Builder is the next generation Idea Builder that continues the Dremel heritage of reliability and ease-of-use while bringing the convenience of Wi-Fi connectivity and mobile interaction to the world of 3D building.

What should you be looking for?

Trying to answer the ‘how much is a 3D printer’ question, many of us give up on essential functionality in advance. We know that professional machines do way more than basic printers, but luckily for us, that doesn’t only mean sacrificing essential features.

There are a number of best-budget 3D solutions that do the same job of their costly versions, and will respond to all your filament requests, printing desires, and compatibility issues. Make sure all capacity is there, and that there is no cheaper printer that can do the same work.

Performance: The issue of speed and resolution

When developing 3D products, experts must consider many factors, the most important of which is definitely accurate calibration and resolution options.

There are printers that level print beds automatically, or allow you to adjust their Z height manually (Z height is in fact the space between the print bed and the extruder). If the print plate is leveled in the right way, all of the models you’ve printed will be accurate.

The operating mechanism doesn’t go too far from the one of inkjet printers, but emphasizes way more on resolution and speed. Draft prints, however, will go out faster, while higher resolution ones will require time and few professional touches.

Size is also very important, as with printers that can’t pull off pieces larger than 5 inches; you will be forced to assemble models piece by piece. Those of you looking to prepare diverse XY and Z objects should give a look to 8 inches printers instead.

Design: The better the design is, the better the prints will turn out

Foremost, you should be looking for a sturdier foundation to build projects successfully. A plastic and light printer may be easy to move around, but won’t handle swaying and replacing as well as a metal-frame, heavy one would. If interested to print using ABS filament and wish to avoid warping, you should also look for a device that has a heated print plate.

Filament & Cartridge: Plan your expenses in advance

Budget-friendly printers help you save few bucks on the initial investment, but some of them can dry the pocket once you actually start working with them. The most you’d spend with an on-budget 3D printer would be on filament cartridge ($20-$50 per kilogram spool for retail filament or proprietary manufacturer cartridge).

We recommend proprietary filament, as it is not that likely to clog the extruder (as long as you’ve picked the right type for your printer). If using universal one, shop around to pick the best offered colors and quality.

Connectivity: Check whether it is usable with your software, and whether it supports wireless printing

Most affordable 3D printers come with free, open-source software you can use to design your projects, or at least recommend a good program for the purpose.

What can really make a difference here is whether you can actually understand how the software works, as it varies from extremely simple (and limited) to ultra advanced Cura-type systems that edit files, change temperature, and allow the customization of virtually every specific task.

A recent, major and convenient discovery is the wireless printing option, thanks to which you don’t even have to connect the printer to your device.

At the moment, there are only few Wi-Fi 3D printers on the market (and the price is not exactly friendly!), but a handy alternative is to get one that works with SD cards to make printing easier. Partial tethering is also an option, where you need to plug a USB cable to the printer, and disconnect it once the first model layers are extruded.

Consider the materials you will work with

Most of cheaper 3D printers work applying the FFF technique, which means that they use spools of plastic filament which is melted, and then solidified to form and extrude an object. In the most common scenario, the filament is either polyactic acid (PLA) or acrylontrile butadiene styrene (ABS).

They have very different properties: PLA, for instance, is the more flexible and smoother option, but users often dislike it because of emitting melting fumes that should be prevented with a heated print bed. ABS, on the other hand, melts depending on its own temperature.

FFA printing is also possible with wood, cooper and bronze compositions, high-impact polystyrene (HIPS), polycarbonate, nylon, UV-luminescent filaments, conductive ABS and PLA, PC-ABS, plasticized copolyamide thermoplastic elastomer (PCTPE), polyethylene terephthalate (PETT), Tritan polyester, polyvinyl alcohol (PVA), and many more.

The melting point is different for each material, which is why you should closely follow the manual of your printer, and limit the choice of an exotic filament to one whose temperature your device can actually control.

Consider the size of the objects you are about to print

When looking and printers, pinpoint such that have a build area large enough to accommodate and pull through the objects you want to print. Consider all three dimensions, or ask the vendor about the largest object the printer can offer (don’t look for exact levels, though).

Most of the 3D printers you will see will have a build area 6 x 9 inches square, or perhaps few inches up/in depth, or few feet extra on the side. Surprisingly, most 3D printers are not squared.

Consider the surface you would like to build on

The printing surface is also very important, but novice designers tend to neglect it. When the platform is good, the object won’t have any problem adhering to it, and be removed easily once printing is completed.

In most cases, the configuration consists of a blue painter tape wrapped around a heated glass platform, where objects would stick and then fall off easily. Good and solid platforms will prevent the corners of your objects from curling upwards. On ABS printers, this is a common problem.

Some of the building platforms will require you to add glue to the surface for objects to stick on, but you have to consider soaking the platform in warmer water in order for the object to come loose and be removed with ease.

Some of the 3D printers come with perforated boards with several holes that are filled with hot plastic during printing. The problematic part is that the object is held so solidly on the platform that it takes a while to remove it. In such case, you should take an awl or a thumb tack and slowly push the plastic plugs off the perforation to let the object go. While cleaning the board, make sure it is not damaged.
