MK3S MMU2S calibration procedure of the IR-sensor failure
Hi team, i just completed assembly of Mk3 to MK3S MMU2S upgrade. I spent hour trying to calibrate the IR sensor with no success. If i move it all to the left the value is 0, if all to the right is 1, so i assume the sensor is alive. I trued to slightly move to the right, but i never get the value to 1 neither with the allen key nor with the filament. Moving che chimney the value changes , so the sensor should be ok.
I have solved following suggestions found in another discussion : https://forum.prusaprinters.org/forum/original-prusa-i3-mmu2s-mmu2-assembly-and-first-prints-troubleshooting/ir-sensor-only-reads-0/#post-137513
