@Phaedrux , probably not...although I ordered a steel knob, I received an aluminum one. Like I said, the knob is only 1/2" thick x 1.5" OD, the motor is about 1-3/4" long, so I think that's a dual stack motor.
When warm, it would run reasonably reliably with at .26A current. After letting it cool down, .5A is not enough to get it moving--it is stalling every time there, now, and .8A is hit & miss. I don't really want to have a long warmup cycle just to get this reliable.
