runout and clog test of laser filament sensor
,with the micro USB you can get the raw data of the sensor and motor, update the mcu firmware, set sensitive value.
if it detect the clog or runout,it will set the output signal line to zero voltage which tell the mother board to pause printing.
so it works with all other motherboard which have run out connector

on this debug board it works well,have been test with TMC2208 TMC2209 A4988
the new small board is on the way, the size is only 33mm*30mm
sorry for not clearly and confused :), the clog began at the point 15, we can see motor is moving but the movement of filament is nearly zero.

On the graph I don't see any difference between normal and clogged plots.
