Just now, between the prints, printer reported: 0300-0d00-0002-0001error , heatbed homing abnormal: … I cleaned the nozzle, checked the plate position - nothing wrong. I started homing - and spot that there are no 3 knocks, just 1 or 2, sometimes 6. So called calibration, it went up to 28 or 32 % then jumped to 0%. and the printer reported another issue: the build plate is not properly placed. As all action were unsuccessful, I pressed Factory Reset, went through all initial setup, all good, then self test failed with this number being displayed on the printer screen: [0x3004000] . All axis are working, the only things that is different is the number of knocks (tap) printing head to the plate. It is not passing homing, calibration, either initial test. I think something wrong with the force sensors, but not sure. Please help.
Just found similar topic: Z-homing failed due to bed position Seems to be a plate issue? - #8 by JoshBear and I see one bearing sleeve is out of position. Thanks to that topic I followed the instruction from it:
Just closing this off. If anyone else has he same issue with the bearing moving up from the plate. The solution is to turn the printer upside down. Use the pully wheels on the base of the printer to move the bed all the way to the top and then press on the plastic around the bearing. It then clicks into place.
Just to clarify: top position means top position of the printer in normal state, so move the bed down up to the end, then press down the plastic around the bearing, then move the bed down again, and press again… 3 times.
Hi
And make sure the print head is over the poop Shute and not above the plate when you do the procedure.
There is a video of the process as well
