DIY CNC Milling Machine From Scratch

[Boyan Silyavski]

Nothing can cure a crappy board with poor filtering on the signals / i don't know what that is exactly but i know some boards are good and have it/ .

I had last week's similar problems, fortunately not with the motor output signals, just probes, switches and PWM output. Neiter filtering of line input, grounding, shielding or whatsoever helped. One of said boards worked well in other machine. All worked fine untill i switched my servos.

But in you case a shielded cable from board to motor drive might help. I have resolved a friends machine similar problem once, changing said cable with a shielded one. Problem solved. In fact his cable was shielded before but wires at end were very large, So i cut them at minimum so all is shielded. Changed cable just to be sure though, as i had a better one at that moment.


Are your cables between this and that shielded?


And by that mean that the shield must be grounded to case
