Thank you so much, I'll try with the expansion connector.

RE: Problem controlling a cnc spindle
Thank you for the reply, but i'm not shure I understood.
The esc pwm imput must be connected to the negative of the fan and at the same time should be connected to the positive of the same fan with a resistor.
Did i misunderstood?

Problem controlling a cnc spindle
Hello,
I'm trying to build a 3dprinter/cnc machine with the Duet wifi but i can't manage to control the spindle.
The cnc spindle is made by an esc and an rc motor, i tested the esc with a servo tester and it is fully working but when i connect it to the fan header i get no movement.
Here's what i did:
Connect the esc using only signal and ground wires to the fan2 pin
Disabled the pwm fan 2
M106 P2 I-1Load a new tool
M563 P2 S"Spindle"Set the board to CNC mode using pwm fan 2 as servo output
M453 P22 R15000Using M3 or M280 command doesn't produce any movement in the motor.
The esc is a skywalker 80A UBEC and it works with 5v signals, the fan jumpers are set to internal 5v.
Am i doing anything wrong?
Can PWM fans output 5v PWM signal?
