Bystronic 4400 Byspeed 3015 Burns random large hole!?

[mwright57]

Hey there, We bought this used laser at the end of last year. We are slowly starting to use it more and more regularly. I was running a multiple sheet nest and when it was cutting out a part it seemed to dwell over one hole making it 3x larger then it should've been and totally deforming the area (see attached picture, the smallest hole on the top of the picture is the hole size it was supposed to be). It continued to run the rest of the sheet without problem. This incident happened twice (2 weeks apart) on just one hole on 2 different parts that were nested multiple times on multiple sheet. Each time it happened I was changing over sheets on the load table and didn't witness it happen.

Was this just a fluke that sometimes happens, or is this something that could become a larger problem going forward? Any help or suggestions would be appreciated. Thanks.

if it's random my guess would be cut control is doing it. try turning cut control off or play with the settings.
