XYZ Calibration Failed. Please consult the manual.
I completed the build today. Goes through iterations of XYZ calibration and fails the test.
No cable obstructions. The piece of paper does not get caught by the print head. The belts are not slipping.

Video? Pics of nozzle , Extruder, belts , gears, etc?
Re: XYZ Calibration Failed. Please consult the manual.
I will take pics and video. Taken me a few hours to get the firmware updated. Didn't realise I had to reboot windies after install. No warning about that and not all drivers require that these days.
So at least the firmware is up to date.
Will take pics and shoot video.

Update:
I got the latest MK3 firmware update on the printer now and since the firmware change the printer doesn't even get to the XYZ calibration stage. It fails on the initial X movement. Complaining the X axis length is wrong.
I will record video tomorrow. Too exhausted tonight.
I checked for cables hitting the x-axis screws but that looks fine.

It wouldn't work for me so I went back to 3.1.3. See the below thread for history of problems.
Re: XYZ Calibration Failed. Please consult the manual.
Thanks for those pics. Can you take one up close to the nozzle that shows how the PINDA appears in comparison to the nozzle? Also interested in one that shows how the hotend sits in the extruder body?
Re: XYZ Calibration Failed. Please consult the manual.
Re: XYZ Calibration Failed. Please consult the manual.
IMO, that nozzle looks a little too low. I cannot upload a pic of my printer now but will do as soon as I can so you can compare. My printer is in a 30 hours print so will not look as good as your shot. 🙂
Your hotend seems to be correctly installed so not sure why/how the nozzle looks low. Can you check that it looks like https://manual.prusa3d.com/Guide/5.+E-axis+assembly/510?lang=en step 19? The relevant area in the extruder body looks dark in your picture.
If hotend is sitting where it should then post a picture of the nozzle and the heating block. It should be very close to the heating block but not touching it but not far away. Step 18 gives you a somewhat good perspective of how the nozzle should fit in the heating block.
Re: XYZ Calibration Failed. Please consult the manual.
I checked the Pinda probe by putting metal underneath it and checking the status on the LCD. Pinda works fine.
Prior to the latest firmware the error was at the end of the XYZ calibration 3rd iteration.
Now I have the latest firmware the error is in the X-axis so I don't even get to the XYZ stage now!

I've checked and the round part of the hotend sits flush with the printed part as in the photo:
I had followed the instructions and inserted the hotend into the printed casing at an angle and ensuring the white tube went down in the hole.
Re: XYZ Calibration Failed. Please consult the manual.
So just to remind you:
Since the firmware update last night I no longer get to the XYZ calibration. It fails on the first X-axis length test now.
I'm removing the cable ties from the extruder bundle and going to refit and make sure nothing sticks out. It's a shame the margins are so tight.
I fitted new cable ties to the hotend bundle. No obstruction to the x-axis that I can see. The printer fails every time on the x-axis test complaining about length.

Regarding X length issue. Check out these threads that explain how people fixed this:

Re: XYZ Calibration Failed. Please consult the manual.
Thanks for links. I followed the instructions in the second link. Removed hotend backplate, took belt off, machine oil rails, test smoothness by sliding head back and forth. Reassemble. It has now passed the X-axis test. Got to the XYZ paper test it catches the paper so I stopped it. I guess the pinda needs to be lower.
Re: XYZ Calibration Failed. Please consult the manual.
Yep, good thing to check for sure. Good progress !
Re: XYZ Calibration Failed. Please consult the manual.
So it completed the XYZ test and all subsequent tests! Have done first calibration print test.
Using a cable tie to set height of Pinda wasn't a good idea. I was just following the instructions. It's now approx within 1mm of nozzle tip.
Thanks for your help!
I will have quite a lot of studying to do to fine tune but at least the major disasters are fixed.

Re: XYZ Calibration Failed. Please consult the manual.
Interesting. Yesterday I rebuilt my MK2s to MK2.5 - and now the x-axis no longer reaches the endstop. There is now a gap of 3mm. I have checked all the cables, nothing is pinched. As if the part, which should press the end stop, just too short.
RE: XYZ Calibration Failed. Please consult the manual.
Sorry to bump an ancient thread, but it took me a few hours of troubleshooting and Googling to realize what I'd done wrong. Nothing I googled revealed the answer, and this is the first Prusa Forum Google hit for the error message.
My printer has a shelf above it, so the spool holder can't be mounted towards the back, so I had the spool holder towards the front. The top X axis rod then contacts the spool holder before the top of its travel, so the printer rightly detects that it does not have the full Z axis range that it expects. The fix is simply remove the spool holder temporarily, though you later run this risk of crashing for an extremely tall print, but I never do prints that tall so it's not an issue. Or, mount the spool holder the correct way 🙂
