IDEX Markforged Home All issue

button

Hi!
I just after month my printer with dual marforged kinematic (IDEX).

Problem that I have is at homing all axis.
I can home all axis separetly, and behavior is correct. When I hit home all i have error:
"Error: G0/G1: insufficient axes homed"

My files for me looks really ok:
homeX:

G91              ; relative positioning
G1 H2 Z5 F2400   ; lift Z relative to current position
G1 H1 X-340 F3000 ; move quickly to X axis endstop and stop there (first pass)
G1 X5 F6000  ; go back a few mm
G1 H1 X-340 F300  ; move slowly to X axis endstop once more (second pass)
G1 H2 Z-5 F2400  ; lower Z again
G90              ; absolute positioning

HomeU:

G91              ; relative positioning
G1 H2 Z5 F2400   ; lift Z relative to current position
G1 H1 U340 F3000 ; move quickly to Y axis endstop and stop there (first pass)
G1 U-5 F6000  ; go back a few mm
G1 H1 U340 F300  ; move slowly to Y axis endstop once more (second pass)
G1 H2 Z-5 F2400  ; lower Z again
G90              ; absolute positioning

HomeY:

G91              ; relative positioning
G1 H2 Z5 F2400   ; lift Z relative to current position
G1 H1 Y340 F3000 ; move quickly to Y axis endstop and stop there (first pass)
G1 Y-5 F6000  ; go back a few mm
G1 H1 Y340 F300  ; move slowly to Y axis endstop once more (second pass)
G1 H2 Z-5 F2400  ; lower Z again
G90              ; absolute positioning

HomeZ:

G91               ; relative positioning
G1 H2 Z5 F2400    ; lift Z relative to current position
G1 H1 Z-300 F600 ; move Z down until the endstop is triggered
G1 H2 Z3 F2400
G1 H1 Z-300 F180
G90
G1 Z5 F1200

And finaly HOMEALL:

G91                   		; relative positioning
G1 H2 Z5 F2400        		; lift Z relative to current position
G1 H1 X-340 U340 F3000 		; move quickly to X and U axis endstops and stop there (first pass)
G1 X5 U-5 F6000 			; odbicie X i U
G1 H1 X-340 U340 F300 		; powrot wolno XU
G1 H1 Y340 F3000 
G1 Y-5 F6000   				; go back a few mm
G1 H1 Y340 F300  			; move slowly to X and Y axis endstops once more (second pass)
G1 Y-320 F4800
G1 H1 Z-300 F600      		; move Z down stopping at the endstop
G1 H2 Z3 F2400
G1 H1 Z-300 F180
G90                  		; absolute positioning
G1 Z5 F1200					; lift Z

I can't figure out whats wrong here...

Hi,

If may be because you are trying to home X and U at the same time.

Try doing them individually.

If that doesn't work you could use "brute force" and comment out lines 4 to 14 and test.

If all is good un-comment the next line and test again.

Eventually you should find the line causing the problem.

If you don't mind a bit of inefficiency you can use my approach.

For you it would look like this:

M98 P"homeZ.g"
M98 P"homeX.g"
M98 P"homeU.g"
M98 P"homeY.g"

That's correct. You should be able to do a first pass homing X and U together, and both axes should stop when the first endstop is triggered. Then you need to home X and U separately. It's the same as for homing a CoreXY printer, see https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter#Section_homeall_g_file.

Thanks for the confirmation.

Did homing separate - working great. THX
