RE: Filament Sensor Calibration failing
4. Still in the Info / Sensor info screen, test the side sensor with something stiffer than filament and approximately the correct width. I happened to have a piece of wire of 1.8 mm. Possibly the 2mm Allen (hex) key works well. What you are looking for is a difference between inserted/not-inserted of roughly 400.
Thanks for this, my Sensor Info wasn't showing filament sensor values (maybe because I have 5 toolheads and there's only 1 info field) but a 2mm hex key did the trick to get side sensors 1 & 2 to pass. Used filament in 3,4,5 without issue.
With calibration finally passed, I went ahead and disabled the side sensors anyway. No more nag message!
RE: Filament Sensor Calibration failing
I had this exact problem and managed to resolve it!
I noticed that when the filament being inserted the screen flashes quickly showing that it's been detected...then back to "insert filament"...and then back to the filament detected screen.
With a finger ready on the button I pressed continue when the filament detected screen flashed the first time. This allowed the calibration to pass.
The filament sensors are clearly detecting that the filament is being inserted upon request with both indicators saying as much, and the calibration stating "Filament inserted, press continue".
However after hitting "continue" it quickly flashes another screen that is too fast to read ("Calibrating ???") before immediately going to fail and spitting me back out to the calibration and tests menu.
I don't know what it's trying to test at this phase, so I have no idea how to troubleshoot from here particularly given that the sensors are clearly working.
I'm on firmware 4.7.1. Semi-assembled unit.
TIA for any assistance!
