I’m using a k40 since a few months now.
It worked very well so far. (around 1 hour daily)
But a few days ago my machine started to work strangly.
I’m trying to know if, I should replace the tube or the Power unit.
Here is how it behave.
At first the cut was more powerfull at 20% thas at 70%.
(Strange, unconviniant but I lived with it for a week)
I Controlled the signal at the exit of the power control panel and it looks fine. The input value at the entry of the PSU was Around 1.8v DC at 20% and 3.8v at 70%.
My version is the one with Digital display with E-stop, main switch, temp meter;
So the % I mention are the values selected on the red digital panel.
Now my machine cut in very weak and discontinued, cutting dotted line.
What test may I do ?
What would be your recomendation ?
Replace the Tube or the laser Power supply.
Best regards Fred
