Large distance between the PINDA probe and the extruder nozzle
I have a Mk3 that I use as an experimentation machine, right now I'm building a holder/carriage for a Flexion HT, but when I do the homing routine, either the nozzle or the PINDA probe are outside the build plate... Are these the parameters I should change? (All measurements in mm, right?)

Yep, this bit.
Hi, I'm Sean. I used to work on CNC machines.
I try to not make mistakes, but the decision is YOURS.

Re: Large distance between the PINDA probe and the extruder nozzle
Hi John,
I may be up against a wall myself. I used the instructions for the Diabase Flexion HT nozzle and now Im getting X Axis Length calibration failures. So I can't print at all. I really was hoping this would work and I wouldnt have to revert back to RC3 again. Thanks for any help!!!
Update: TL;DR my post https://shop.prusa3d.com/forum/others-archive--f66/self-test-error-x-axis-length-t13327-s10.html : Use a paper under the PINDA height adjust process when moving the extruder (Step 9, Preflight). Rotate the threaded rods down until it contacts the paper and prevents it from sliding. Then raise it just a little bit so it slides without much/any resistance. Repeat for the right side. Move to the center and use a paper on the bed when also using the PINDA sensor adjustment with the zip tie.
Also consider the tension on the belts, try for 250 (lower number -> tighter). Getting belt tension down to 260 or 250 would be ideal, just dont break something. Support->Belt status. The numbers should be lower and ideally 250 for each. A higher value = looser belts. I didnt change the belt tension (mine were too loose at 270 and 310). Good steps that describe that are here ( https://manual.prusa3d.com/Guide/4.+Z-a ... g=en#s9981 and Y axis belt https://manual.prusa3d.com/Guide/2.+Y-a ... g=en#s8225). Reportedly the Support->Belt status values update after passing the self test. [/b]
