RepRap: Printrboard Surgery

After a hiatus of a couple of years, I’m finally starting to get back into 3D printing. One of my Printrboards got messed up when some wires on my hot end shorted. The hot end temperature was no longer reading correctly. Since my other Printrboards all work correctly, I knew that the problem was not […]

Arduino 1.0.5-r2 for AT90USB1286 and Printrboard

It’s been a few years since I hacked together the copy of Arduino-0022 that’s been floating around the web, which lets you compile and automatically upload Arduino code to an AT90USB1286. This made it a lot easier to develop Arduino code for the AT90USB1286, and in particular to easily modify the Marlin firmware for the […]

Marlin for Printrboard Updated

I just synced my Marlin branch for Printrboard with the latest code from ErikZalm’s branch. I noticed that there were a lot of changes in the planner, temperature control, etc.  Hopefully, it will be an improvement, rather than breaking anything.  Please report here or on github if you find any anolmalies with the new code. […]

Printrbot Build

My Printrbot from the Printrbot’s Kickstarter Campaign was supposed to arrive in February. Unfortunately, due to the huge number of supporters they received, the schedule has been pushed back, and I doubt I’ll receive mine until late May. In the meantime, I’ve been getting antsy waiting for mine to arrive, so I decided to go […]

Bootloaders for AT90USB1286

While the AT90USB1286 MCU in the Teensylu/Printrboard can be programmed with an ICSP or JTAG programmer, you can also install a bootloader, which will allow you to program it via a USB connection alone. Besides the convenience of not having to attach a hardware programmer, uploading firmware via a USB bootloader is blazingly fast. Also, […]

grbl CNC Firmware Ported to Printrboard

If you want to use your RepRap for CNC use, such as milling PCB’s, regular 3D printing firmwares might not be ideal. For instance, Marlin is not able to handle the slow step rates used for CNC work. I have ported grbl, a firmware specifically for CNC use (from which Marlin derived its acceleration routines), […]

Repetier Firmware Now Runs on Printrboard

I spent this past weekend porting Repetier-Firmware to Printrboard and Teensyduino. It took me a while to get it working properly, because the code intermixes calls to fastio and Arduino, and the pin definitions in fastio.h were different from the Teensyduino Arduino library. It is now working pretty well, so Printrboard and Teensylu users now […]

Running Marlin Firmware on a Printrboard

As of this writing, the official version of Marlin firmware from github does not yet work with Printrboard.  Printrboard is a fork of Teensylu, designed by the folks at Printrbot. Printrboard isn’t yet available for purchase, but since the design is open source, anyone can download it and get the PCB’s manufactured themselves. Sprinter is currently […]

How to Program an AT90USB1286/Teensylu/Printrboard with Arduino and USBtinyISP

My first step in loading Marlin RepRap firmware into the Printrboard is to get Arduino to play nicely with it.  The method I am going to describe in this article for programming a Printrboard with Arduino will work with the Teensylu or any other device that uses the AT90USB1286 and has an ICSP connector.   […]

RepRap – 3D Printing Project Kickoff – Printrboard First Look

I have been somewhat intrigued by the RepRap project, an open source 3D printer movement, for several years.  However, wasn’t motivated enough to jump into the fray until late last year, when I saw Brook Drumm’s Printrbot on Kickstarter. With only about 1 hour left before funding closed, I pledged $500 to get a Printrbot kit. […]
