OK, so GF want a $1000 for me to shipping to get my unit to and fro GF HQ where they will check it out.
In the meantime, I think it is a temperature problem. Those same files printed fine this morning when room temperature was just 15 degrees. Whereas they fail quite quickly when room temp is 25 degrees.
But cuts are unaffected, long 20 minute cuts are going through fine. So suggestions as to why engraves could be more temperature sensitive and what I might do about it.
Unit is well ventilated and I have an additional puller fan on the exhaust which seems to make no different to failure time. All the exhaust and both head fans are well cleaned.
There is no temp indicator on the UI so I’m not seeing any temp warnings.
Just to repeat. About 1,2 or 3 minutes into an engrave unit stops. Head stops moving, no laser, but fans etc still running. It never clears, only way to get out of it is to power off the GF. The timing is variable, even when printing the same thing over and over. Moving the file and rotating it in the UI still fails. GF have said “can’t remote diagnose, send the unit back”.
