What postprocessor do you guys use for a CNC with a duet 2 wifi?
I tried multiple ones like:
Workbee
RS-274
Mach2
Mach3
They all don't work with the duet 2. Like when I send it to the machine it just goes to the home position.
I hope someone can help me with it.
I fixed it !!. my endstops were on NC, I put a ! in front of it to make it a NO and now it works
I used the normal code for the home command and the M574 in my config.
I found this other forum post from a guy with a similar problem. https://forum.duet3d.com/topic/20318/mpcnc-duet-3-sbc-dual-endstop-for-x-and-y-axes?_=1609092505581
And I read from this link https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors#Section_In_RepRapFirmware_Num_3
that @Veti provided that in 3.0 and above you don't have to separate the axis.
Thanks, @Phaedrux for noticing my error in the code, that would probably have taken me a day to figure out.
@Veti i am using 3.1.1 (2020-05-19b2).
Thank you for the link. this is definitely helpful.
@dc42 this is my config file.

I am very new to the CNC world. I am making an MPCNC with a duet 2 wifi (latest 3.0 firmware I think). it uses 5 NEMA 17 motors.
X - 2 motors, 2 endstop
Y - 2 motors, 2 endstop
Z - 1 motor, manual zero
I got the motors working with the M564 S0 H0 command.
Problem is when I want to home the X and Y axis. I want to use a dual endstop system so it squares automatically.
I don't have any experience with writing Gcode so i generated a part of the home gcode with the RepRap configurator.
when I press homeX or homeY it only moves the z-axis about 1cm up and down and it says home failed. this is my file to home the X axis. the Y axis it
; homex.g
; called to home the X axis

I hope some of you can help me.
