Re: Filament Extruder - Convert pellets to filament
Ian - what you want to do is use a detector for the loop and the output of the detector varies the control voltage on the motor controller to cause the motor to speed up or slow down. This is dynamic control based upon the position of the filament's location. Since you are using a pot to vary the speed now you should be able to use that point as the voltage control point for loop control.
