Interference bewteen Laser Power and Electronics problem

Postby AnthongRedbeard » Sun Nov 03, 2013 2:10 pm

I have RAMPS 1.4 electronics that I'm using with a 60w laser power supply.
I things working pretty well in general, mechanical movement, firing, my software toolchain.

The problem is that when I do a full power fire of my laser I lose communication with the electronics, every time. I have tried to make sure the USB cable is not close to the power supply, and that the laser cables are as far from electronics as possible, but they are still fairly close

Any suggestions on how to handle this? Should I separate the common ground they share? Do I need to build some kind of case around something? Or maybe just buy a shielded cable. I know I should be able to use SDRamps to keep the job going but I still don't want to lose communication.

thanks,
