7i95T spindle control via Modbus RS485 and SPINX1A

Category: Driver Boards

Normally, you would set the PWM scale to the spindle RPM
at SPV+ (so if the spindle RPM is 3000 at 10V, you would set
the PWM scale to 3225 (3000*10.75/10)

Then the PWM value is set directly in RPM.

If you have issues with non-linearity, check
that SPV+ is constant at different spindle settings.
Other possible causes of non-linearity are PID settings
or incorrect PWM frequency

Homing switches dont react, CNC goes on.

Category: Basic Configuration

everything does as it should (input is normally 1, if it touches it opens ->0),

Have you checked that the relevant pins
'joint.0.home-sw-in'
'joint.1.home-sw-in'
'joint.2.home-sw-in'

Change from 0 to 1 when the switch is activated?
