Bed Leveling fails when calibrating after a new build

Bed Leveling fails when calibrating after a new build  

Eminent Member

I worked on repairing my printer's head this week, with a new nozzle, heatbreak, and heaterblock. The printer turns on fine, the initial tests all pass properly, but the printer fails on the First Level Calibration.

The exact error I get is 

Bed Leveling Failed. Sensor didn't trigger. Debris on Nozzle. Waiting for reset.

I looked at why this error happens, and tried to follow the instructions on the online FAQ. That hasn't resolved the issue.

I am also not sure if my bed is aligned properly. I noticed that when the nozzle touches the bed, it descends. But doesn't descend evenly, and only the front part descends, while the back part stays as is.


I have 2 videos of what happens when I run the 1st layer calibration, and I want to know if there is a problem that is easily visible here. Both calibrations were run separately twice.

It appears to me that for some reason (???) the system is not sensing the increased current draw from the Z motor(s) and therefore is not able to determine the Z position.  It looks like a significantly excessive amount of force on the print bed, as the system attempts to find a zero.

If this happened to me, I would probably contact support, as something is definitely wrong.

Does your pinda sensor work?

Look in manual how to adjust the pinda sensor.
