hi
we have a GF at our hackerspace, and we’ve had a few hot days where the GF was not able to run during the day because it was too hot, so a few people came at night or ealy morning to use the GF
just after that it just shut down in the middle of a cutting operation (just goes dead) even the lights go out… cleaning it seemed to help, (vacuing the cutting surface, cleaing off the tube with a cloth, and using a airduster where possible.
but it just happened again and even after cleaing it does not come back up i did notice that the last thing i saw in the web interface was “allert cooling” but i have a thermometer staning right next to it and it’s about 21 C right now
