Re: Grbl with Synthetos Grblshield

Rob, I guess you are still using the stepper motors you posted on the wiki page http://www.shapeoko.com/wiki/index.php/User:DrRob with 400 rev? ... I don't know if this will help, but I uploaded some video of my Z-axis running in full-step, 1/2 step and 1/4 step modes, in an attempt to show the diff...

Now the big question is should I select 1/2 step like Wilafau o...

loading GRBL to an Arduino

I do have a AVR JTAGICE mkII and I have Linux Mint 12 64bit. The Arduino is a Seeeduino V2.2 with a AVR labeled "ATMEGA328P AU 1019". From what I understand this should be compatible to GRBL. ~/Downloads $ sudo /home/markus/arduino-1.0/hardware/tools/avrdude64 -C/home/markus/arduino-1.0/hardware/too...
