Hi all
New Ultimaker user here and first time posting on the forum. Just want to say that this forum has been really useful for me in the last month doing little jobs on the UM2 I have here.
However I've now run in to a problem that I can't find when searching.
I've recently done some maintenance to the machine after a failed overnight job that made a real mess! I've fitted a new olsen block and nozzle (the originals got blocked up with material), changed the tension on the feeder (it had started grinding the filament down instead of feeding) and re-levelled the bed.
Despite all this, when printing (using the same files that I've had previous success with on the same printer) the build plate is not dropping sufficiently for each layer. What ends up happening is the nozzle drags itself through the print, making a squeaking noise, and you end up at the end with a job that is rougher than usual and about 1/3 the correct height! Z switch seems to be working correctly and I've re-levelled the build plate a few times now.
How do I fix this?
Many thanks
