Would it be worth running an earth strap between the laser and pc chassis?
@donkjr Sorry for the very late response on this thread, It seems that a new usb lead has stopped the connecting/reconnecting. Thank you once again for all your help.
@Andy_Shilling thats “Shilling” news :), noise never ceases to surprise me.
Can you post what USB cable you bought?
@donkjr I went with this one

@Andy_Shilling Which wiring diagram did you end up following for this Laser PSU? Are you a 100% up and running now?
I’m almost finished building a 60w laser and I have the same terminals on the LPS. I was just about to use the first diagram with the Test fire btn set to TL to G. But wasn’t sure which wire needed to go to the Cohesion3d. So if was reading along correctly, did you do Test fire as TH to 5V and wire TL to the C3D terminal P2.5?
@Bill_Keeter if you scroll back up the conversation you will see my really bad writing sketch. I don’t think I changed it after that but could confirm it later when I get home from work if needed.
