right hand side of the bed giving bad first layer
Hi,
I've had my prusa mk3 (kit for a month or so now and i have had constant issues with the optimal first layer height needing altering every time i use the printer with the right hand side of the bed giving the worst results. After reading this post ( https://shop.prusa3d.com/forum/hardware-firmware-and-software-help-f64/1st-layer-problems-in-depth-look-at-software-pinda-t14815-s10.html ) which highlighted a similar issue i updated the firmware with the Firmware 3.2.0-RC2 last night. Though this has eliminated the requirement to adjust the z value for every print the right hand side of the bed still gives a much poorer first layer than elsewhere. I have adjusted the bed compensation by -50um and though it improves the problem slightly it is still poor. After investigation into the pinda temp via the support tab i noticed that the pinda temp is 35 C during mesh bed leveling except when it measures the 3 positions on the right hand side of the of the bed when the pinda probe temp reads 0 C. Any ideas?
Thanks in advance

Well the pinda temp is now 0 all the time but the light on it is constantly lit.

Could wire fatigue only affect the temperature reading of the pinda without disabling it completely?
Does it look like the extruder cable bundle is being stressed when the carriage is extended to the right? Zipties too tight?
Re: right hand side of the bed giving bad first layer
Zip ties are fine but i cut them anyway just to be sure. I also checked the pinda cable for any signs of pinching and it has no marks whatsoever so its probably just a defective cable.
Re: right hand side of the bed giving bad first layer
My pinda cable looked fine, but failed internally. I patched out the section between the einsy case and the cable support on the back of the X axis, and functionality returned
