I’ve had the error come on a couple of times now and I’ve been able to fix it following this
https://glowforge.com/support/topic/troubleshooting/reseat-printer-head
& this
https://glowforge.com/support/topic/cleaning-service-and-moving/clean-air-assist-fan
Now the error is still on no matter how much I clean it.
I see that the staff can turn the alert off. I will need that too.
Also is it hard to replace the fan; as I cut wood mainly. Thx!
