My Cheapo Chineese 3020t mini CNC Build (more like improvements) leanring all the way

Screened cable without the screen being grounded is acting like un screened cable. so ground the screen at one end. It may not make a differnce, but if you have screened cable, it makes sence to use it how it is intended to be used.

in the control cabinet and to a star point.

and make sure the cabinet is also grounded.

not too sure what a star point is, how do I connect it to the metal braid screening?

This has been talked about many times on here try a search !! Read some of the build logs etc you don't seem to take advise when offered

[ravihotwok]

Advise welcome, instructions even better. Searching is great, but is something can be answered in a simple sentence then that saves a lot of time. Will do a search now and see what I can find.

That wiki link explains a lot. Except the best way to go about physically achieving it.

I now understand what a star point is. Can I splice into each of the motor cables just to expose the outer metal braid, then solder/heatshrink a cable to it which can then me linked to a star point in the box?
