So my exhaust grate and fan blades were showing a lot of dust and debris accumulated after a month of regular use, cutting and engraving wood. Yesterday I gave the fan and grate a cleaning with canned air and shop vac. Once I fired the machine back up and sent a job, it was immediately clear that something was wrong. As the laser started working and the fan fired up to full speed, it was now much louder and vibrating the glowforge, easily felt by hand on the back left corner.
I submitted a help ticket with support and am awaiting reply. But in the meantime, I’m curious if anyone has figured out a way to lubricate the fan with machine oil? I don’t see an easy way to get into the fan housing, but I hate to have to send the entire machine back to California for maintenance if it’s as simple as extracting and lubricating the fan.
