VORON CORE XY CHANGE THE ORIGINS OF THE AXES

Gianluca

I'm finishing building my new Voron 2.4. I have already set the x,y and z homings. However I would like to have the origin in the lower left and not in the upper right. Is it possible to do this?
My system uses a Duet 3 6HC board and Toolbard 1LC, and I have the latest beta firmware installed.

In addition when I homeall, the second pass is only done for one axis and not for both.

Thanks for the tips.

@Gianluca you need to swap the endstop location in M574 from low to high (e.g. M574 X2...).
Then change the homing files from moving to the minimum to the maximum.
And in homeall rather than G1 H0 to move away for the second pass, the use G1

@Gianluca To get the motor direction correct, see https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_coreXY#testing-motor-movement
For homing, you currently have your endstops set at the 'low' end of the axes, with this in config.g:

M574 Y1 S1 P"!io1.in" 
M574 X1 S1 P"!io2.in"

You haven't marked where the Y endstop is on your image, but I assume as it is mostly working correctly, that too is on the 'low' end currently. You will need to change the M574 settings to set the endstops to the 'high' end, by changing X1 and Y1 to X2 and Y2 (see M574 for details).

You will also need to change your homing files so the axes home to the 'high' end. Additionally, the method to home an CoreXY is slightly different, which is why you are not getting the second pass, as your homing files are not quite correct. For more details on this, see https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_coreXY#homing-files

Change your homeall.g to something like the following:

; homeall.g

G91                   ; relative positioning
G1 H2 Z5 F3000        ; lift Z relative to current position
G1 H1 X350 Y350 F4000 ; move quickly to X or Y endstop and stop there (first pass)
G1 H1 X350            ; home X axis
G1 H1 Y350            ; home Y axis
G1 X-10 Y-10 F6000      ; go back a few mm
G1 H1 X350 F360       ; move slowly to X axis endstop once more (second pass)
G1 H1 Y350            ; then move slowly to Y axis endstop
G90                   ; absolute positioning
G1 X15 Y15 F6000      ; go to first bed probe point and home Z
G30                   ; home Z by probing the bed

Thank you very much! Now I finally understud out what to do, I'll try tonight. Unfortunately the understanding of the English language is not good. I now understand the concept of low-end and hight-end of the guide...

Gianluca

Great, now everything works as I wanted. The indications received were perfect. You can mark it as solved, thanks!
