Problem with cutting on Bystronic 4020

[filipov1975]

Good day to all. We have a problem with our laser. The first slice of the day is perfect, and then gradually things get worse. With 100% power on screen, the power reaches 2500 watts. Then changing the parameters is not a result. Slice remains the same with any parameters.

if you restart the machine does it clear up? might be time for a resonator rebuild.

Hallo, thankyou for responding me. The problem not exist only with the first cut. Nothing is change with restart the machine.

I had a similar if not the same problem 6 months back with my bystar 3015 ended up being the arc mirror. That's the first mirror on the outside of the cabinet. It didn't look damaged, spotted or dirty but it was increasing the size of the beam and causing all sorts of cutting issues.

If you ask me to do something, I will do it. There's no need to nag me every 6 months

Nothing is changed. All is clean, everything look good. But the cut is same.

is there a paint coating on top of your material or rust? spray wd40 on top of material before you cut it should help

you only get 2500 watts at 100%? what are you supposed to get?

Hallo, if the laser is 4000 W how many is 100%. But the strange is another thing. On the morning when i cut the power is gone to 3200W, after half hour of work is gone to 3000 W, and after half hour is gone to 2700 W and is cutting all the day with 2500 -2700 W, always in 100%.

Has it always done this since you've had it ??? or just recent. If the power is decreasing you may have an faulty Excitation module. How many hours do they have on them ???

Hallo,i have this problem two monts ago. What is "Excitation module"?

Hi, we still have the problem. But now with thinner sheets. The power in the thinner sheets is the norm, but the cut is the same. There are no splashes, the details are detached, but the cut is jagged. By the way, I had an error with ÖVER CURRENT error and decided it by changing the cable nozzle in the laser box.
