Hi Waleed

Could you tell us what brand/Controller/laser type you have?

Normally the issues you are describing are a controller crash related.
if you unplug the laser head (assuming is a diode) and run the project as is will the behavior happen again?
(it wont engrave, but machine motors will move)

If yes, you might have a power delivery issue and a power adapter change might be required.

Did you already exchange the USB cable? This is a very common issue with Sculpfun S9s. Here is a list of things to check if you have connection issues:

You are professional, I’m a electronic programing and designer, and I thinking about cable also, I using the cable that came with this machine, but I will change cable with other , maybe resolve, and I will see the Guide you sent, many thanks to you.

Make sure the cable includes a ferrite (big knot) on it. If you specify a USB cable for the S30 Pro, you will get the proper one.

Thank you, yes the cable have that ,
