I need some help guys. My new to me 1988 Fadal 4020 has been a work in progress. But I can run a short program from the Calmotion USB but not larger programs.
At first I thought it was my Fusion 360 putting out strange code but I had a professional check it out and he said the code was good.

So basicaly it will stop short then jump back to the beginning of the program and start from the beginning.

Any ideas ?
Baud rate is set correct -9600

CD,8 (enter)
DNC, 1008.txt+

Is how I get the controler to read it.

Looking for suggestions.

Calmotion USB was baught new Oct 2020

Thanks!
