Hello Guys,
I have a trouble with my PSU unit output. I have a 100W tube with An M100 230v clourday PSU. The controller is a Ruida 6445. I was trying to setup the 100% correctly at 28ma so i touched the little screw inside the PSU. Worst move ever, now my PSU doesn’t ouput more than 9ma (whatever is the screw position) when i cut a project BUT when i press pulse on the controller, it generates 29ma and the tube is working perfectly.
Do you have any idea where i messed up with this ? .
The PSU seems to be capable to generate the power (because the pulse button works) and the screw modify this output
The Tube is almost brand new and seems perfectly fine
The controller is a Ruida 6445 and i tried differents settings with the same output.
It’s a good idea to set this properly and the few I’ve done and assisted with are 20 turn potentiometers so you have to really crank them to change the output.
I’d suggest cranking it back up.
Set the PWM to 50% on the console with the duration ‘continuous’. This limits the current 50% and you mA meter will read 50% rms of the current.
I have a 21mA max tube, and the lps is for a larger tube. When I test it at 50% it delivered 14mA, indicating it’s actually drawing 28mA when it fires. So I lowered it to 10.5mA (half of the 21mA tube limit)
If it’s a GCODE laser, make sure the max S power is set properly in Lightburn. If it’s supposed to be 1000, but it’s set at 255, then it will burn at lower power.
If you set max power on the console, that’s what the pulse button will deliver for what ever the duration is set. It’s ‘continuous’ or you can set a mS time.
Ok, I did a lot of checks of the ruida and lightburn, the ruida seemed fine. So i double checked lightburn and resetted all parameters from Lightburn and everything works perfectly now. I don’t know what i touched in lightburn but agood reset is always useful.
