Everything working, but Z always reports position as"?"
Hello - my printer is AWESOME! But I've noticed an odd problem.
After building, I ended up having to update the firmware.
I used the firmware file "prusa3d_fw_3_4_1_MK3" and compiled+uploaded using Arduino IDE.
Everything worked great on this, and the printer works in every respect.
But, no matter what I do, the Z value doesn't show up on the screen! Z adjust functions work, so I think it's a programming error wherein the active Z value isn't being passed to the LCD.
Anyway, has anyone had this issue? Apologies if this is a duplicate, I did a quick search but didn't find anything.

It is often discussed on GitHub: IMHO You did not follow the Readme and forgot some compiler flags during compilation.
May I ask why you compile the firmware yourself? Prusa provides a compiled firmware for you:-) I am not sure if you were aware of that

Ah thanks I'll read through the GH information.
I inadvertently used the mk2 firmware and loaded that via slic3r. Once that happened avrdude would timeout on the bootloader reset, so I ended up solving that issue by using the arduino IDE and it's apparently different avrdude calls. I guess at this point I could simply upload the correct hex file using slicer.
thanks!
