MMU3 Filament Sensor Unreliable
I'm trying to get my second MMU3 working, and I am having a lot of trouble with the filament sensor. I have made a series of adjustments to the screw in on the extruder, and have recorded the results to find the proper adjustment. That screw is extremely sensitive. Even 1/8th of a turn makes a significant difference, but according to the display during the filament load, the best I can do is about 75% success. I have also installed a couple of different filament sensors with the same results, so I know the sensor itself is OK. My other MMU3 machine doesn't have this problem, and neither do my other MMU2 machines, for that matter.
Has anyone else encountered this? How do you get consistent readings from the filament sensor?
RE:
To say this sensor is unreliable is an incredible understatement. This design is terrible and cripples the entire machine. What were they thinking replacing a sensor that works with this shit? I'm going to try redesigning with the ball. This shit is dumb and support would have me tied up for months again so I'm not even asking them. I really wish I'd never heard of prusa. My a1 combo is running circles around 3 prusas that constantly break.
