Added physical buttons for Run/Resume, Pause, and Reset as well as a Z probe button. Makes life so much easier when doing tool changes or just getting the Z set now. Also added some edge guides so I don’t have to keep using a square to make sure my workpiece is square to the machine.

Do you have more pictures? How did you wire it?
No more pictures right now. I’m using an input module from bdring on tindie. All 4 buttons are wired to that.
Also worth noting that this is a jackpot board. I wouldn’t know how to do this on a Marlin build.
Hey would mind to link to the input module from bdring? And perhaps share a few more details on how you did this?
I think that is the one he used.
That’s the module.
There is another post that shows which input goes to what GPIO. Then you have to set the buttons to the correct GPIO.
I used the control section of the FluidNC to set the correct options in the config.yaml.
Control (Inputs) | Wiki.js (fluidnc.com)
For the Z probe I assigned that button to Macro3 and then used this for the macro:
Here are my setting changes in config.yaml.
macros:
startup_line0:
startup_line1:
macro0:
macro1:
macro2:
macro3: G38.2 Z-80 F200 P5.02&G00 Z10.0000 F500
after_homing:
after_reset:
after_unlock:
control:
safety_door_pin: NO_PIN
reset_pin: gpio.15 (input 3)
feed_hold_pin: gpio.13 (input 2)
cycle_start_pin: gpio.14 (Input 1)
macro0_pin: NO_PIN
macro1_pin: NO_PIN
macro2_pin: NO_PIN
macro3_pin: gpio.12 (input 4)
fault_pin: NO_PIN
estop_pin: NO_PIN
*Remove the parentheses when adding to config.yaml
For Marlin, this can be done by using an Arduino and injecting g-code through a serial connection. With Marlin, you may not get an immediate pause since pause commands are put in the queue.
