FSensor Issue
Hi guys, I'm having a bit of an odd issue. I just got finished building my MMU3 and attaching it to the Mk4. I recalibrated the filament sensor on the extruder and it passes every time, but after the test, it's like the filament sensor stops talking. If I manually load filament into the extruder to test it, the value at the bottom of the screen doesn't change. When I also tried my first print, the printer failed as it wasn't detecting the filament being loaded into the extruder itself. The PINDA is working perfectly, but this new filament sensor setup Prusa came up with is just giving me a TON of issues.
Anyone run into this issue when they first assembled the MMU3? If so, how did you fix it?

I figured it out, Prusa's guide for assembling the sensor is off. They mentioned tightening the tension screws to where they're completely flush with the idler. I had to loosen them 1/16" and now the sensor is working reliably.
