Smooth out motor movement #6

Closed laurb9 closed 7 years ago

laurb9 commented 8 years ago

Starting the motor at full power causes it to miss step sometimes, depending on which intermediate position it was on. We should start slow and build up to max rpm, then slow back down to reduce shake.

This is a StepperDriver issue mostly likely.

Increasing current alleviates this problem somewhat. Horiz motor aref is now at 0.3V vs vertical at 0.2V

Can now use LINEAR_SPEED mode available in StepperDriver 1.1.0
