Re: PROBLEM WHITH TEENSYLU - 12 years ago
There are jumper pins for setting the microstepping. It is underneath the stepper drivers. I haven't tested SD card support myself, but the add-in SD card for sanguinololu should work (it was made to be compatible.)by StephS - General Mendel Topics
Re: PROBLEM WHITH TEENSYLU - 12 years ago
Hi Juan. The reprap wiki has pretty detailed instructions on how to flash the Teensylu board. Follow the instructions on setting up the arduino environment, and make sure to edit your boards.txt and select the teensylu board in arduino. You need to install FLIP to program when using the built in bootloader. Install the FLIP software first, then remove the boot mode jumper on your board and reseby StephS - General Mendel Topics

OSH Logo was contributed by Joem, he put it on Sanguinololu 1.1, so it copied over. I also like remote stepper drivers, though it does increase the amount of wires running around the machine (not by much). In it's best configuration, the stepper drivers should be mounted nearby to the motors (even on the motors themselves). I'll be working on getting the BOM compiled soon.by StephS - Controllers
Re: Introducing Teensylu - 14 years ago
I personally solder 0402 and 0201 components. I also do QFN and lots of other fun things by hand. For real USB compliance some of the components should be 0402 and smaller traces. 0603 might be a good comprimise, I am contemplating making another version which would add some of the often requested features like a 5th stepper controller, dual endstop, and SD support, though that would require a neby StephS - Controllers
Re: Introducing Teensylu - 14 years ago
Make sure you're using the latest version of Eagle. I'm using 5.11.0 Light. I just downloaded the files and it worked. hmm. The Teensy and Teensy++ are microcontroller dev boards produced by PJRC seen here: My board is based off their core design. The Polulu controllers were chosen because it's a known interface, and it's mostly available. In the future I plan on making a new interface and stepby StephS - Controllers
Introducing Teensylu - 14 years ago
The Teensylu is a fork of the Sanguinololu project. It's original goal was to simply replace the atmega644p Microcontroller with the AT90USB1286 Microcontroller used in the Teensy++. We quickly realized the the extra I/O the AT90USB1286 provides can give us some more functionality without loss of compatability with Sanguinololu. The Teensylu was designed with SMT devices in mind.
