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 [...]

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), [...]

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. [...]
