Hi,
I have a red and black Chinese laser with TL 403CB DSP and change my PSU for the Jupiter 100-180W.
I have a W6 130W reci
Installation was easy, test fire was Perfect but when I send something to cut, the laser won't fire.
I double-check all my cable color and all were connected to the same IN G WP L ports.
My old PSU was a regular eBay bought 150W PSU and worked well for 2 1/2 years.
Does anyone know what could be?

Usually it is water protection issue. Check the WP connection on the power supply. It has to be either grounded or connect to a water sensor. Or, you need to have your controller hooked up to the chiller.

Thanks for the prompt feedback Marco!
But the chiller is connected to the machine and sensor beeps when I block the water.
When I push test button, laser fire perfectly.
I bought another PSU, now the same one from the machine DY20, it will arrive this week and i will make a test.
I found a knob on PSU, my old one doesn't have.
What is this knob for?
Is there a manual for this PSU?
Thank you again!
