|
|
; X Axis: drivers `0.0` and `0.1`
|
|
; Y Axis: drivers `0.2` and `0.3`
|
|
; Z Axis: driver `0.4`

|
; ### Endstops
|
|
; There is an end-stop on each drive axis (ie 4, 2 x X and 2 x Y).
|
|
; They are configured as active-low with a pull-up resistor (ie they should
|
|
; always be high, which prevents possible failures where the end-stop isn't
|
|
; connected anymore).
|
|
; Pin mapping:
|
|
; - X0 `io0.in`
|
|
; - X1 `io1.in`
|
|
; - Y0 `in2.in`

; ### Z-Probe
|
|
; Unlike the end-stops the Z probe is a touch-off plate, so should be
|
|
; active-high.

; ## Fans
|
|
; Fan 0 is connected to out4 as a 12V 2-pin PWM fan
|
|
; Sensor 0 is the temperature sensor on the Duet3 MCU
|
|
; Sensor 1 is the stepper driver temperature sensors
|
|
; Turn on the fans when the MCU reaches 40º and on max at 70º
|
|
; Also if the stepper drivers report over temp
