Hey all my brand new k40 laser engraver arrived today and I could not

Hey all my brand new k40 laser engraver arrived today and I could not wait to plug it all in. I have it all set up but now I cannot get it to power on except for a brief moment after checking all of the lines and then unplugging the switch connector and plugging it back in there was a whirl of the coolant fan and LEDS. Does anyone have any info they can share or hot fixes that I am overlooking?

May need a little more information:
Have you proven the mains are live?

Some has a fuse in the back where the connector is, check it if you have one, and if its burned or not.

It’s all sorted now, the emergency stop button was tripping even though it was no depressed. A quick spring replacement and rebuild and bam laser time. Thanks for the assistance

Hey that is the second time I have seen a problem with the ES button, should have asked if you had one :(.
