I have cleaned the feeder (yes the black one), several times. It seems like it just cant push it trough and then slips, releasing the pressure, that causes the filament to stop flowing for a little while. Machine on for: 2246:27 Printing: 1159:56 Mat: 779m

I think the Z- as is not the problem. That is because I see this happening on the first layer. (you can see it a bit in the previous picture on the brim. The filament was not tangled, it was an almost new role and I use two extension for my filament https://www.thingiverse.com/make:364760 https://www.thingiverse.com/thing:388560 I have also already updated the firmware to the latest version. The teflon part looked ok to me, a bit dark at one end (is that normal?) but it did not look deformed. So what are the 20 other thinks that could be wrong. (thanks for your help)

For the last months I have problems getting good prints. It seems that suddenly the printer does cannot get any PLA trough the nozzle. The filament push motor (do not know the correct name) retracts and almost at the same time only drops come out of the nozzle instead of a steady stream of material. Thinks I have already done: - Cleaned the nozzle (seemed to help for some time) - Put the temperature to 225 C. (seems to help) - Bought a new nozzle (did not make much difference) - Cut a few centimetre of the bowden tube (because the end got damaged) - Put a bit of oil in the bowden tube (seems to help a bit) - Print in the front of the build plate (seems to help a bit) - Used different filament (does not seem to make a difference) But once in a while I still get prints as shown in the picture. I think I have tried everything. What else could go wrong? Please help!!

I have found the problem. (after I completely dissembled the printer). It seemed that the nozzle was clogged. After cleaning it, the printer works great again. It remains strange that I could touch the nozzle. Thanks for your great advice.

My last print looked really strange. When I tried again there was no filament coming from the nozzle anymore. I also noticed that the nozzle was not 210 degrees as the display stated. I could touch it with my finger, it was not even warm. So if the nozzle is not warm, nothing comes out. So I guess that ether the temp sensor or the heating element is broken. But which one? If any one can help, that would be great.
