I was in the middle of a 44 count tumbler run and about half way it dropped down to about a quarter of the power. I stopped the project and rest the laser and reset the computer and kept getting the same issue. I then noticed it had changed the frequency from 30 to 75 in the middle of the run in the materials settings. I did not exit the rotary marking control panel when it changed the setting. I changed it back and it was back to normal.
So, why did it randomly change the frequency in the material setting in the middle of a run of the same tumblers???
Its a Gweike G2 Max 50W Ok getting weird results. Not happening in the native software from Gweike.
When I reduced it down to 30 khz from the 75 khz (Which I had in a library setting from before) it worked again. Then it was scorching it and I tested it back up to the 70 khz and it is back to normal. When it dropped in power it was during the tumbler to tumbler burning using the Rotary Marking screen
And never exited back to where I could change the material settings. Now I’m back to it being 75 khz and it is the same as when I ran the other 184 tumblers. So I do not know exactly what happened.
Now, I don’t specifically rule out the laser as I just worked with the engineers and found out when LightBurn jumped to 2.0 it would stop jobs in the middle and state it was complete. Tracked that down to not being able to use a USB hub between the computer and laser. Either the signal was too week or something else was going on.
Another thing. I did have a separate material marking the bottom of the tumbler and it also cut down to 1/4 of the power. I never touched that setting only the main material setting and it also returned to full strength. So ??? Not a newbie, have 100w CO2 Omtech and a lot of died lasers for years. But I am a few months into using a fiber laser and those settings.
