Brief spin Motor starts "cavitating" - can be heard attempting to operate but spindle is stationary Breif spin again System freezes & will not spin again until board is reset
That indicates, to me, that the motor is trying to accelerate to a speed that it is not capable of, buzzes, and then the deceleration gets to the point that it can run and then stops. The system freeze could be when it hits a soft (or hard) limit. Does $X unlock it?
If you are using G00 commands the motor will try to accelerate to the max speed at the acceleration in the config file. Try it using G01 commands with a much slower speed. Then you might need to make changes to the config file to match what the motor can do.
Are you using micro stepping?
Have you checked your power supply voltage when the stepper is jittering?
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Have you just got ONE DRIVER and ONE STEPPER and code to JUST CONTROL that ONE STEPPER, so that you can get your driving code working before making the problem twice the size?
Can you post your complete code , using code tags please?
presumable because these are absolute positions?
With the limited data on the Steppers is their a how to guide on how best to test and set these values to match the motors? or is there some way of calculating the optimum values?
So presumable this indicate the default GRBL acceleration / deceleration / feed rates settings are not compatible with the stepper motor. With the limited data on the Steppers is their a how to guide on how best to test and set these values to match the motors? or is there some way of calculating the optimum values?
