My desktop CNC router's first cuts

<< < (3/3)

MadModder:
The import of the breakout board schematic did not go very well. It looks ok, but whatever I do all components become black opaque squares when I try to export it to PDF or something.
I found a PDF of it from 2008 though. The explaining texts are in swedish, but you'll get it anyway I suppose. The symbols are universal. :D

MadModder:
I actually found a PDF with the schematic for the motor controller. In a mail from 2007. Yay for backups  :thumbup:
It's mostly taken fom the datasheet.
One of these for every motor, and they plug in to J3 / J4 / J5 / J6 on the breakout board.
The chip is Allegro A3979.

MadModder:
An old photo of the first test of the boards:

Biggles:
looks like something for the future, thanks for the pdfs.  :thumbup:

Manxmodder:
Thanks for showing this project. I don't have room for anything like this at present time,but I really appreciate how useful an addition a CNC router would be. Great project,well done  :clap: :clap: .......OZ.
