Constant 'Calibration failed. Please consult manual'  

Re: Constant 'Calibration failed. Please consult manual'

What is the error message exactly?

Re: Constant 'Calibration failed. Please consult manual'

Vojtech

When this happened with me, the calibration completed and gave the same error message "Calibration failed. Please consult manual."

After rolling back to 3.0.5, the calibration stopped at point 7. Doing it again and watching, it was possible to see that the probe was really having a hard time searching for the point.

Turns out that the probe cabling was failing and point 7 was stressing it (repeated fast movement) so much that continuity was lost.

Thanks Peter for heads up.

Yes, it could be the intermittent induction probe cable.

If the calibration process stops over some random bed induction sensor point, then it means the algorithm did not find that particular point.

> "Calibration failed. Please consult manual."

If the calibration stops after the full first round of 4 calibration points in a diamond pattern,
or if the calibration stops after the full 2nd round of the 9 calibration points, then it really means, that the machine measured all points, but they are so far from their expected positions, that there must be something wrong with the machine. Very often it is the slipping pulleys. Quite often it is the induction sensor too high.

Of interest to you is following:

"XYZ calibration failed. Bed calibration point was not found." Calibration routine did not find a bed sensor point. The printer stops close to the bed point, which it failed to detect. Please verify, that the printer is assembled correctly, that all axes move freely, the pulleys do not slip and the print nozzle is clean. If everything looks good, re-run the X/Y calibration and verify with a sheet of paper between the nozzle and the print bed, that the print nozzle does not touch the print bed during the calibration routine. If you feel a friction of the nozzle against the sheet of paper and the nozzle is clean, you need to screw the PINDA probe slightly lower and re-run the X/Y calibration.

"XYZ calibration failed. Please consult the manual." The calibration points were found in positions far from what should be expected for a properly assembled printer. Please follow the instructions of previous case

Re: Constant 'Calibration failed. Please consult manual'

Yes, basically lower the probe which EasyCheese says he has done...

Unfortunately, because the latest firmware completes each phase and presents the error at the end, unlike 3.0.5, there is not indication which probe point cannot be found.

That is not correct. If the latest firmware cannot find a single point, it will stop over it. But quite often the single points are found, but they together form a pattern, which does not fit the model of the machine. Then you get this "consult the manual" message.

Vojtech

That is correct with 3.0.8. It didn't happen with 3.0.6 (and possibly 3.0.7). I know this because my calibration is failing again, but the failed point varies, with point 4 on the second phase being the most consistent. For some reason, point 4 is found during phase 1.

Peter

Re: Constant 'Calibration failed. Please consult manual'

I got the same error repeatedly with 3.0.7 (at point 4), then I did factory reset and after that the calibration passed OK. Just FYI.

Thanks for the info. I have done all the factory resets different firmwares lowered probe etc.

My Mk2 has already run all self tests and calibrations successfully on 3.0.5, 6, 7 and 8. I think the printer is actually suffering from pre-exhibition nerves... Fortunately, the Mk1 is printing well.

Re: Constant 'Calibration failed. Please consult manual'

Peter, try to downgrade to 3.0.3, that version worked quite well. I hope it calms your MK2 down. 🙂

Re: Constant 'Calibration failed. Please consult manual'

I'm having this same issue. Is rolling back the firmware really a fix?

Wow thank you so much for this input Vojtech. I had assembled my mk2 a few days ago and have been desperately trying to pass the XYZ calibration since. After simply tightening the pulleys on the y and x axis. The calibration passed with "XYZ calibration OK. X/Y axis perpendicular. Try this first people! I spent days altering the frame and probe and I probably never needed to. Printing my first model as we speak. Thanks again!

RE: Constant 'Calibration failed. Please consult manual'

i have the same issue with my i3mk3s

but it stops after point nr4 in the first round.
i adjusted the PINDA probe and checked it with a piece of metal, drove it manually across the heatbed and checked it worked properly around the calibration points, but still the test fails.

no restriction in movement along any axis, no zip ties sticking out and getting stuck while moving.

i have no clue what the problem is. 
factory reset done already.

Hey,

just checking, did you end up finding a fix for your issue? I'm exprecienceing the same thing. Have tried all the steps from the manual and the factory reset. Nothing seems to fix it.

Thanks!
