Spindle speed control P/port
Chinese bob blue relay. Problem on switch on the 0-10 volt from the BOB is at around 10V so starting the spindle with m3 the spindle is at full speed.
On the Axis gui in manual on the spindle control the + arrow make the spindle slower and the - faster.
Should the 0-10v be low on switch on? if so can I just change the pwm scale to -

Setting the PWM pin to inverted should fix that, in hal.
setp parport.0.pin-04-out-invert TRUE
Chang the pin number.
setp parport.0.pin-04-out-invert TRUE
Chang the pin number.

That solved it. I also had to calibrate it using this :-
