Is there support for Pellet auger #25

Closed mvogt99 closed 8 years ago

mvogt99 commented 8 years ago

I looked at https://github.com/CapnBry/HeaterMeter/wiki/Blower-and-Servo-Wiring and am wondering if the Servo mentioned was intended to control a Pellet auger? ... or how support for an auger (including into the PID functionality) could be added?

CapnBry commented 8 years ago

Nope, that's actually something completely different. The pellet auger is either a stepper motor (i.e. the controller sends a single pulse to advance the auger X degrees) or a geared motor (i.e. the motor moves continuously just very slowly due to high gearing). The servo code is for driving a hobby servo, which operates by moving to a position specified by the duration of a continuous pulse. They're fundamentally different and not interchangeable.

I can't think of a way HeaterMeter would control the auger but you might want to ask on the forums

Thanks for the quick reply... as far as hw goes, I'm guessing something like this might work... https://www.pololu.com/product/2755 ... just need to incorporate it into the PID algorythm. Btw, I believe the auger motor is a gear motor.

I'll inquire on the forums.

Thanks again, Mike
