I have two #1478 Stepper motors, GRBL 0.8 software on an arduino, DRV8825 drivers running now and does anyone have links to understand:
resonance limitations in stepper systems,
limits of accellerations and speed and “loosing steps”,
effects of different voltage and current levels
Basically I’m trying different things and trying to understand why i.e. the motors stop if I command too high a speed, or accelleration, which interacts with step mode (full, half, etc) and voltage and current too it seems. It also seems the GRBL software has some small errors in the regularity of step generation at higher speeds I think which causes the motors to stop or lose steps.
I’d like to find choices to do say, 500-800 rpm, any low accelleration is ok. 200rpm seems easy but it’s limiting for my purposes. At 500-1000 rpm, the motors stop and “sing” a lot. Is this resonance? Or from completely loosing step synchronization? I DO understand there are limitations to what this can do. I’m just trying to understand that better.
