Problem with Z axis, I think...

Wed Jun 13, 2018 10:37 pm

So, my prints keep failing. At the 7th bed leveling point (counting down from 9) right before printing, the extruder dips far into the bed, so much so that there is a dent in the bed now, and I get an immediate error telling me "Bed leveling failed. Sensor didn't trigger. Debris on nozzle? Waiting for reset."

This is how it all started:

Everything was printing great earlier today. Then, on one print it started printing from too high up and was kind of dropping the filament onto the bed. I stopped the print and tried it again. Same thing. Then, I did a full XYZ calibration from the menu. That seemed to make things worse somehow. That's when it first did it's major dip on that fourth bed leveling point and dented the bed.

Now I can't even get through one print. Any suggestions? I even tried reinstalling the firmware. Nothing. HELP! Thanks in advance!

Hi Jeanette,

have you got the latest firmware loaded?

are your X and Y axis moving smoothly?

did your selftest work ok?

did you do a factory reset before re calibrating?

Thanks for your response, Joan.

I think I have the latest firmware loaded for the MK2. I actually tried loading the firmware for the MK3 after this happened and it made the printer inoperable completely. So I went back to the most recent firmware for the MK2.

My X and Y axis are moving smoothly.

The selftest worked.

I did not do a factory reset. How do I do that?


I am also wondering if there is some problem with the sensor. How would I know if that were the case?

Thanks so much! I really need to get the printer running again, as we use it at my library. I'm getting behind on prints!

Hi Jeanette,

Factory RESET IS A BIT MISLEADING...

it actually means clear non volatile storage for currently loaded firmware

it is actioned by holding down the input knob on the lcd, whilst starting the printer, or resetting the printer, with the X button on the LCD Front panel

you them have options displayed to select language, and reset all data.

this may make re calibration work for you,

Okay, thanks Joan. I tried the factory reset (the simple one) and it didn't work. Any other ideas?

I'm currently checking out the XYZ Calibration & error messages (MK2) article on Prusa's help page. I hope I get some answers here because this is freaking me out :)

Thanks!
Jeannette
