Back again.
Slowly progressing with my hardware for the 4-axis hotwire cutter.
I have read that probably the best software out there for my specific application is GMFC (RC foam wings, including stacked airfoil cuts, creates airfoil G-code and direct drives the stepper control board).
Problem is, all the reading I've been doing about GMFC software, seems to indicate it only works with a specific driver board.

Has anyone got any experience or info on the possibility of using the TB6560 board with GMFC software ?

thanks
Rick
