    I recently purchased the openbuilds motion control x32. Really loved the software, and the plug-play type hardware. I am connecting my existing spindle (DC48V 300W SPINDLE MOTOR - -) to 24VDC supply, and using a decent enough driver (25Amp 7V-58V High Voltage DC Motor Driver). The driver is powered externally, and the PWM is provided by the blackbox x32.

    The problem is, when I start the spindle on the CONTROL software (Tool On -> Variable Spindle -> M3 S1000), it immediately starts running at that speed. And what's worse is, when I put it on a lower speed (S50, for example) or turn off the tool - it immediately drops to low speed / stops, respectively. This is not good for the spindle motor or the driver circuitry (bearing wear & tear, high back emf).

    Is there any option in the CONTROL software to ramp up / ramp down the spindle speed?
    If not, please provide alternate options (editing grbl code, adding macros, etc.).

    Thanks for the help.

    Duplicate of support ticket 66345 - please check your email for reply from the store.

    Please avoid cross posting to multiple support channels :) Effectively talking to the same people via multiple channels - not always a good use of time :)

    Thanks

    Apologies for the same. I was not able to find the ticket in this website account, hence thought it might not have been registered.

    Thanks
