Cutting issues, Bystronic 4kw: holes missing and sometimes side of the part

[yannick53]

Hello,
we meet a problem on our 4kw Bystronic. Sometime the machin doesnt cut the holes, and even the side of the piece which should be cutted.
We can see the moving of the head but the machin doesn't cut (like no laser beam).
At the beginning of this issue (already 2 or 3 years ago), we just knew that the machine was missing some hole maybe 2 or 3 times a year. Bystronic said that it was a problem of software, so we upgrade it but now the problem appear more an more often. SOmetime once a day, then duraing 1 week no problem, then appear again.
Then 3 or 4 monts ago, we can see that the machin doesnt cut also some side of the parts (new symptom).
We already change many card with bystronic but still the same.
Bystronic ask us to make a RAMDUM (when the problem appear). So it means the operator has to stay in front of the machine and when he see the problem appear, make the RAMDUM. So, we save 2 times the files and send it to Bystronic Swiss but still on investigation.
Do you have any idea?
Best regards
Yannick

Just what software did they have you upgrade? Bysoft or the MMC/Byvision?

Open the top of the resonator and try to cut again. If the head is on the material and you see a bright glow in the resonator, it should cut, if it does not cut them there's issues w the shutter. if the glow gets all unstable or doesn't get brighter, then there's other issues. This will cut the suspects in half.
