Min. rpm for linear_profile #89

Closed sigurdild closed 4 years ago

I am loosing steps during acceleration and deceleration.

I have done some testing with DRV8834 and this stepper with gear. https://www.omc-stepperonline.com/economy-planetary-gearbox/nema-8-stepper-motor-bipolar-l38mm-w-gear-raio-641-planetary-gearbox-8hs15-0604s-pg64.html

It cannot run below 300rpm with microstepping set to 2. This is an issue when using acceleration.

Is it possible possible to generate the velocity profile starting from a value higher than 0.

Thank you!
