Topic: Can you help to solve a problem with filawinder?

HI! For the unclear reasons from time to time thread of plastic falls below the lower sensor, at this time the engine on the coil begins to rotate (1-2 seconds), and then sharply stops and is not twisted any more and thread begins to fall on a floor. Up to this point there can pass the random amount of time after the beginning of extrusion. If during this error to lift thread again and to pass below a sensor the engine starts over again rotating to the following such fail. what could cause this problem?

Try doing the calibration again, but move the filament slowly past the sensors, take about 1 second for each pass.  Also make sure the laser shines straight along of the sensors so they get the same amount of light.  Make sure the laser is held tight so the line can't drift.

What do you mean by "pass"? I use about 2 years 24/7 and it is the first such problem at me. Whether there can be a problem in electronics, for example - the transistor in PWM?

you push the calibration button and slowly move a piece a filament up and down throught the laser beam range so it learns
