Motor Interfaces

Interfaces for bipolar motors

  • MDLCNC, 4 motor Interface 4,5A, sold by rc-letmathe, compatible with the GGC adapter. The GGC is directly pluged to the MDLCNC using the parallel port. This is my personal setting.

MM2001 interface for unipolar motors

While unipolar motors are a little bit obsolete, there are still used on many foam cutting tables. For these motors, the MM2001 remains one of the simplest to Do It Yourself. Designers are Michel Maury, Jean-Francois Delhove, Alain Gleyze and Gérard Prat.
