Running Then Stopping Then Running Again
Calibration failed, check axis and run once more
Calibration failed, check axis and run again
I ran the self test (finally) and everything came back ok. (One slight weird thing. X axis check moves, Y axis moves the bed, but Z doesn't motility at all.... seems strange to me, but the Cocky check says ok?)
Also I tried to manually move Z and it seems to move the right Z motor, but the left seems... slower? sluggish?
Anyway, later on the cocky test I tell it to calibrate and information technology immediately fails. "Calibration failed, check centrality and run again"
What does this mean?

Re: Scale failed, cheque axis and run over again
Perhaps you turned that black ring close to the motor itself too tight on the left Z-Axis motor?

Re: Calibration failed, check centrality and run once again
I am also having trouble with my left Z axis... sometimes sluggish, sometimes won't move at all. Disassembled and reassembled multiple times now and tin't find anything skewed

Re: Calibration failed, check axis and run again
I ran into this problem too subsequently doing a firmware update. Have you lot been able to solve this issue?
*edit*
I was able to solve the issue by going back and adjusting my hotend. Apparently, I didn't install it correctly and it was far lower and so it was suppose to be. Please double check that your hot end is the proper position!

Re: Scale failed, cheque centrality and run again
Aforementioned problem here with my new MK3 kit, latest firmware.
Same result whether doing it through the wizard, "Calibrate XYZ", or "Calibrate Z".
Mesh bed leveling works fine.

Re: Scale failed, check axis and run again
Ran into this problem just now, I fixed it by jogging the Z up to the top of the frame, where it hits the Z holders. I noticed 1 of the Z trap basics, was noticably lower, and adjusted it manually with my hands to the match the height of the other Z trap. Now the calibration is running fine.

Do you just mean that the Z carriage was lower on ane rail than the other? That'southward automatically corrected during the calibration since during Z-homing to the tiptop the routine keeps running until both steppers are skipping. So I'chiliad surprised that stock-still it for yous.

Re: Calibration failed, check centrality and run again
Yea during the test, it was stopping nearly a quarter of the manner upwards, I estimate the commuter's detected some resistance im assuming that one side being lower than the other crusade some friction, then the commuter's assumed it hit the top and started to come up downward where it failed when the sensor detected the bed earlier than expected. I thought it was normal behavior for the examination to just go part of the way up, till I read more than of the manual.

Re: Calibration failed, check axis and run again
Yes that, exactly that (in hindsight). I was trying to have the X-axis carriage left and correct same heigt on the Z-Axis using a ruler but never got higher on Z-centrality than i/quaternary of the way then it stopped every time during XYZ calibration. And so I discovered the transmission Z-Axis move option in the carte, went all the way to the top until motors skipped one time and and then down et voila XYZ calibration could be done... machine home on Z-axis is still an effect but I'm printing (close to two days at present almost non-stop and in need for new filament 😀 😀 )

Re: Calibration failed, check centrality and run again
Well I found my upshot. I misassembled my extruder past mounting the hotend besides low (surprisingly I had several skilful prints this style, but discovered the upshot when I had trouble changing filament). Pretty embarrassing, but anyhow I'm glad I institute the issue!

Re: Calibration failed, bank check axis and run again
This is going to sound like a impaired question, considering I feel dumb right now afterwards virtually 12 hours of insanity (doing the same thing over and over and expecting unlike results). Why would the hot end existence misaligned cause the Z axis to not movement?
I'one thousand having this problem also, where the Z axis isn't moving properly. I tried to raise it all the way but information technology requires manual assistance to move upwards (Which I know will be a problem for printing). --I tin can't solve this and this is my main business concern at the moment.
I'thousand besides having the calibration mistake, which I call back is partially due to the Z axis, but might be the hot end (I'll accept to have autonomously and check).
And so I estimate I'm asking, is this two separate problems, where one plays into the other? Or is it one over-encompassing upshot?

Re: Calibration failed, check centrality and run over again
Then.. I stock-still the Z centrality not moving properly. I had to undo and redo the entire black ring thingy.. It looks similar information technology was cross-threaded or something similar.
I'm still having calibration issues.. So time to cheque the hot stop I guess? How tin yous tell if it'south too low? According to the pictures, mine looks right.. only I presume information technology must not be?

Re: Calibration failed, bank check axis and run again
Glad y'all made progress, just please identify the "unabridged black ring thingy" so we know to what you are referring.

Re: Calibration failed, check axis and run once again
Glad you lot made progress, only please identify the "entire black band thingy" so we know to what yous are referring.
Oh c'mon that was totally understandable by me 😛 The Z screw cover. 🙂

Re: Scale failed, cheque axis and run once again
I think alexander.t2 means the trap nut ;).
Anyway with my issue (which was quang.northward's issue also apparently) the z axis was moving fine but gave the same error, presumably from having less than expected full length. Clearer error messages would be helpful hither but these are all forms of user fault so can't blame Prusa.

Anyway with my result (which was quang.n'due south consequence too evidently) the z axis was moving fine merely gave the aforementioned error, presumably from having less than expected total length. Clearer mistake messages would be helpful hither merely these are all forms of user error so can't blame Prusa.
I really meant the spiral cover (That goes on the bottom), not the trap nut. http://manual.prusa3d.com/Guide/iv.+Z-axis+assembly/509?lang=en#s8168

Re: Calibration failed, cheque axis and run again
I had the same trouble and in my case I had put the spool holder facing the front end of the printer so the Z-Centrality wasn't able to get all the mode to the peak when calibrating.
Elementary fix to change the holder.

Re: Calibration failed, check axis and run again
i simply got this same error. i found what the trouble was... i forgot to plug in the pinda probe. aye stupid me. 😳

Re: Calibration failed, check axis and run over again
I think i fount the problem. The last step of the build leaves your extruder downwards and left. During XYZ calibration, the Z doesnt move and then stay down left, but says ok. Ran it vi time but failed every time. Sorted it out by turning the printer off, moving Z all the way up and the turning on and restarting the wizard.

Re: Calibration failed, check axis and run once again
Same issue here, I installed the heating chemical element in the "lower zone". 😆
