only one small problem when I fire the laser to cut or engrave it never goes above 50% on the amp meter and it still takes the same amount of passes as it did when it was a standard k40 …it now has a 50w tube and 50w rated psu
I have put a new 10 turn pot in case it was that and have tried jumping the IN and 5V but neither make a difference
I’m assuming it is something in the config somewhere ??
One thing you can try is to use the original 40W PSU to test with. It is actually capable of running a 50W tube. This will rule out the new PSU if you get the same results.
