Calibration Failed: Check Axes
Hi All. Wasn't able to find any topics on this issue, so please point me in the right direction if I missed a thread! I have a brand new mk3 printer, assembled by Prusa. Prints would stop about halfway thru so I decided to recalibrate....now I can't get past it.
The z axis runs up against the top during calibration and clicks, then fails to let me proceed to the next step. The error I get is "Calibration Failed! Check the axes and run again"
A few things I have tried:
1. I tried the master reset since I found that in other threads, but still no progress.
2. Self check runs and everything is good
3. The screws all move freely by hand.
Any help would be appreciated!

Re: Caliration Failed: Check Axes
I tried this the other day, and the solution that worked for me was this:
lower the printhead until the nozzle barely touches the bed on the two front corners. I used a piece of paper underneath the nozzle to ensure that I didn't quite touch the bed, then dragged the head to the other side. Be careful not drag it on the surface itself.
Basically I lowered the head til about 2 millimeters above the bed on both sides before I lowered it on either side.
run calibration.
And this allowed the head to move all the way up.

Re: Calibration Failed: Check Axes
Thanks for the feedback. Did you move it manually (with your hands) with the power off or with the control panel(settings->move axis)? When I turn the printer on, I can't move the z axis lower than the position was when power was turned on.
I tried both ways with no change in calibration. After the calibration fails, I can't manually adjust Z using settings--> move axis more than a couple millimeters.
Seems like the hardware is ok and this is some sort of software issue?

I reached out to Prusa support. They had me check the trapezoid nuts, but they seems to spin freely.
