Calibrating Z axis issue with dampeners and some R2 parts
I added dampeners for all stepper motors - X, Y, and Z axes.
2 of them installed for X and Y are from here: https://www.matterhackers.com/store/l/3d-printer-motor-vibration-dampers-4-pack/sk/M4V3JGJ9
The other 2 are from here attached to Z axes: https://www.amazon.com/Stepper-Rubber-Vibration-Dampers-Printer/dp/B073FRZTDX
I have added dampeners to a wanhao i3 duplicator plus no problem..
I assembled parts of my printer using the R2 printable parts here:
https://www.prusa3d.com/prusa-i3-printable-parts/
I have also completed even this part of the instructions:
https://manual.prusa3d.com/Guide/9.+Preflight+check/514
I assembled my Prusa i3 MK3 kit (I'm a week 13 buyer), and I get this error when calibrating:
Error: "calibration failed - check the axes and run again"
The X axis seems parallel based on the instructions and I am able to pass the self test on the axes part, but I can't get it to calibrate here. Looking for any suggestions or feedback from experience you guys might have run across if you have installed dampeners. Thank you!

Your trapezoidal nuts are upside down.

hah!! Rookie mistake of mine... let me try that out when I get home. Thank you 🙂

So I flipped them the other way around and the issue still persists. I also took the extruder cabling apart to correct the cable management and make sure the head goes all the way left on the x axis.
Adjusted PINDA probe up and down to see if any difference... Still same error
Re: Calibrating Z axis issue with dampeners and some R2 parts
Should the metal build plate be on for that z calibration?
Re: Calibrating Z axis issue with dampeners and some R2 parts
Looks like you have assembled your extruder incorrectly. The E3Dv6 hotend is not in the correct place, it is too low. This makes the Pinda too low also and means the Z axis is too short, hence the fail.
Go back to the assembly instructions and redo the extruder, and make double sure that you assemble the hotend so that it matched the images exactly. Good luck!

Ultimately this last suggestion provided by Alfred resolved my issue and I was able to proceed past the error with the rest of the process after the Z Calibration.
Then adjusted the PINDA again based on instructions from https://manual.prusa3d.com/Guide/9.+Preflight+check/514#_ga=2.238035392.196868585.1527602463-1404784823.1520892867

Martin's suggestion helped with this, I made sure my trapezoidal nuts were oriented with the protruding center faced downwards instead of facing upwards (as you are looking at the assembled X axis piece attached to the Z rods). When I was reading the instructions on the printed paper booklet I had poor lighting in my assembly area (the dining table) so I missed this part.

Re: Calibrating Z axis issue with dampeners and some R2 parts
Yup. I also found the online manual was far better than the printed one when it came to assembly. 🙂 The pictures in the printed one are a bit to small to make out the important details at times.
