    I recently upgraded to the black box x32. I am running the latest firmware on the black box and interface. I followed the guides to set up the HY01D511B VFD Controller (watercooled). I am using aspire 11 and have modified the code to add a pause after the M3S code is sent to give the spindle time to ramp up to the rpm that is set in my tools setting. For some reason, the g4 P, code pauses the system, but the spindle never spins up until it starts cutting and the rpms are very low. Once the spindle is cutting, when it lifts up to begin cutting in another area the spindle rpm drops and then goes back up when it starts cuttign again. I am at a loss of why this is happening. I looked at the gcode from aspire and there is only one M3 S code being sent at the onset of running the code. I have reset and reprogramed the VFD but it is still doing it. I have tried setting a pause for spindle in the grbl settings of openbuilds (max of 20 seconds) and this doesnt seem to do anything. What am i missing?

    Do you maybe have Laser Mode enabled in Grbl Settings?

    Yes, laser was enabled, once that was turned off, everything is working perfect. I have the opt laser on my system as well, it’s hooked up to the pwm pins. Will it still work with laser disabled? Thanks for your help!!

    Laser mode on for Laser jobs, Laser Mode off for router jobs. Create macros or add $32=0/$32=1 commands to your CAM workflow so the gcode sets it for you

    So I make two post processors in aspire, one for laser using $32 = 1 and the other for CNC with $32=0? Where do I put this? Is it before the header in the parameter area of the code?
