I have two Monport GP30 Galvo Fiber Lasers that are only used to run pens through a rotary table. I typically run a few hundred each day. Fairly often during one of the batch processing the laser will lose a significant amount of power (I would say 20-30% of the typical power setting) for one iteration. After that iteration is complete it would be back to normal for some time. During a batch of 24 on my rotary table typically anywhere from 0-4 pens have this intermittent power issue. There doesn’t seem to be any rhyme or reason on which iteration it happens either, and appears to be completely random. I’m fairly certain this is a software issue and looking for suggestions. Here is some trouble shooting/things I have noticed:
-The issue occurs on both laser (which are identical).
-The issue persists across different computers.
-Once the low power iteration starts, stopping the engraving and starting a new iteration doesn’t seem to fix it. You have to wait for the iteration to complete for it to go back to normal.
-This person seemed to have the exact same issue, with the exact same laser.
I have tried all recommendations including this one in an attempt to fix it:
When you first set up your device in LightBurn, did you import the markcfg7 file from your EZCad folder? If not, your Device Settings in LightBurn are likely incorrect, and could be causing the reduction in power output.
Anyone have any ideas? Fixing this issue would greatly increase my efficiency and lessen my frustration.
