Problem with core XY homing

Dad003

i tested something here i removed the second homing pass on bot X and y , didnt get the weird homing behaviour maybe i just need to remove the second pas in the home all as well maybe .

Dad003

so i tested this again , home all doesnt get weird behaviour and seem to actually track to the number it move ,

modified home all that work

; homeall.g
; called to home all axes

G91 ; relative mode
G1 H1 X-240 Y-240 F1000 ; coarse home X or Y
G1 H1 X-240 ; coarse home X
G1 H1 Y-240 ; coarse home Y
G1 X130 Y125 F3000        ; go to first bed probe point and home Z
G30                     ; home Z by probing the bed

; Uncomment the following lines to lift Z after probing
;G91                    ; relative positioning
;G1 Z-5 F50             ; lift Z relative to current position
;G90                    ; absolute positioning

while homing X alone , it reach the limit switch web control show 0 , homing Y hit the switch than Y show 0 but X has now a negative number even if it didnt move

i added a g92 in all homing program now the axis after they home do not get change to a negative value anymore and everything seem to track correctly . i will test more and come back if any issue . this conversion has been a lot of headache so far from the config .

Do you understand what a G1 H1 move does when the endstop of the axis is triggered?

@fcwilt

Yes when the endstop is trigger is zero the coord ,but in my case i had weird behavior for unknown reason, i had to find a workaround until somebody has a better solution

That is not correct.

When the endstop is triggered the axis position is set to the axis min or max value as specified in the M208 command for that axis.

If the M574 command for the endstop specifies low end then the axis min value is used.

If the M574 command for the endstop specifies high end then the axis max value is used.

That is likely why you are not getting the values you are expecting.

; Endstops
M574 X1 S1 P"!io0.in" ; configure active-high endstop for low end on X via pin io0.in
M574 Y1 S1 P"1.io1.in" ; configure active-high endstop for high end on Y via pin io1.in

What kind of endstops do you have and how are they connected?
One of them is inverted and the other is connected to an expansion?

Could you show a video of the behaviour to help me understand what you mean?

Can you also provide the results of sending M122 and M98 P"config.g" in the gcode console?

@Dad003
What Phaedrux wanted to point out, is you have a typo in the definition of the Y-endstop:

M574 Y1 S1 P"1.io1.in"  
should be 
M574 Y1 S1 P"!io1.in"

Everything you've done are just bandaids to coverr the real problem

@o_lampe that limit switch is on an expansion board not the mainboard .

mainboard control 2x Z , 2x Y, 2x extruder expansion board has the 2 X axis motor with that limit switch. if i remember correctly the limitation of the expansion board the limit switch has to be with the board controlling the axis

OK, my bad.
Doesn't the switch on the expansion board also need the '!' to invert the input?

Dad003

@o_lampe

no , like i say my printer started as a cartesian so when i switched to core xy , i didnt touch the config for the limit switch since they were working like they should .
