SIlicone tube spacer mod

RE: live z height > 2.00

If you’re close to or above -2, I would reposition the PINDA higher.

May sound counter-intuitive to move the PINDA higher, but by doing so the nozzle can move closer to the print bed before the PINDA triggers. For an illustration of relationship of distance of PINDA to nozzle and sheet, see

The Super PINDA should have about 1.5 mm distance between nozzle and sensor, so that you’re around -1 when your Live Z is correct. That gives you enough wiggle room up and down.

Instructions for adjusting the PINDA are in:

Mk3S: https://help.prusa3d.com/en/guide/how-to-replace-superpinda-mk3s-mk3s_179920

I put this little gadget on Printables to help position the PINDA: https://www.printables.com/model/57192

Works better than zip ties or credit cards, which have less well-defined heights.

The height you now have is the height of the ziptie. So that is OK. 
Please use an old creditcard instead. That is about 0,8 - 1 mm
When you do the Live Adjust and go dot with -0.600 to -0.800 you get the same numbers as others. 
to sumup: 
- You use the ziptie, creditcard or whatever to give the PINDA a known distance of the bed. 
- with setting the Live adjust you narrom this down. (NB: If you would go down to the bed with the nozzle (DO NOT DO THAT IN REALITY) you will see the same number as the height of the ziptie/creditcard). 
- The difference between thickness and live Z result is your actual nozzle/printing height.
