Yes, I just installed the lastest firmware today, no improvement though. and Yes, just the glass plate, no other printsurface.

Hi there, I'm having an issue with the active leveling of my UM3. The active leveling sequence goes completely as planned, no abnormal behaviour whatsover. However, when I then start a print the printer seems to have "forgotten" the data because the nozzles gets pushed into the bed (about as far as it does when active leveling). because of this the nozzles doesn't extrude any filament whatsover. This happens every time I try active leveling. About a year and a half ago I replaced the capacitive board & cable because I thought it broke (wasn't there when it happened but the active leveling actually shattered my bed). After that it worked fine for a few months but then the active leveling started acting up. At the time I didn't want to do anything about it because the manual leveling worked fine but now I just want the active leveling to work. btw, I have tried active leveling and printing with the front fan disconnected (read on the ultimaker support website that it could cause interference) but that did not help unfortunately. Thanks in advance!

Hi all, Has anyone ever upgraded the radial fans of an Ultimaker 3? I have to slow down my print to about 20 mm/s to make sure the overhangs don't curl up. I figured that if I upgrade the radial fans so they cool better, I can print faster and still cool sufficiently. Yet, I don't know if there are fans that fit in the print head, cool better and won't draw too much current (assuming this could be an issue). Does anyone have any info for me? A quick search on Google, Reddit or this forum didn't give any results. Thanks!
