50w Chinese laser issue after new power supply

Post by matthewcoxall12 » Tue Jan 19, 2021 5:51 pm

Having this issue after replacing my power supply on my 50w Chinese red and blue laser.
nothing has changed in the software and all mirrors are aligned, have been searching google for a few hours but have not come up with a solution

also: Laser fired when i switch it on and leaves a small cut line when traveling to the start point. it does cut fine but engraving is all messed up

My New power supply is a MYJG50W and have attached my wiring as per old PSU.

on the engrave/Cut image it was the same shape for cutting and engraving but came out like this

You can check first that it isn't due to a connector or wire having come loose.
