Error 9 G-code locked out during alarm or jog, homing enabled

I read to use $33=750 it said ok but still is not working. How can I unlock the g code?

$33 is PWM frequency and generally should never be below 1KHz. (1000). Typical is 5KHz to 20KHz. Never seeing one run at 750Hz, though not that far from 1KHz. Safe settings are 5KHz (5000).
I do not believe it has anything to do with Error 9, but who knows!

You can unlock it with “$X” but your homing has failed. You need to fix that or if you are comfortable to run without homing - disable it: “$21=0”.
