Error on home all

percar

I have upgraded my duetwifi firmware to 3.01RC2 and I am getting the following error while doing a homeall. G28. It is a minor glitch as the printer still functions however it is a nuisance.
If I do a home using individual axis homes there are no problems and no errors
My homeall,g file is as follows:

could be because homeall calls xy before z; but x and y moves z.

try reversing the order?

@percar said in Error on home all:

;Home All
G29 S2
G28 xy
G28 Z

The reason is, that for G29 the printer must be already homed. You should move G29 to the end.
Standard for homeall.g is a combination of the code of homex homey and homez.
That saves time for z-movement.

percar

I should have mentioned that this is a Cartesian printer
G29 S2 disables the height map which is what is required in order to home the machine
If height map is still enabled then when z homes it will home to the compensated z position which will cause a positional error.

percar

Just saw that G28 must be homed before using this command......missed it

DIY-O-Sphere

@percar

That would be the combined code for your case ....

; homeall.g
G91 ; relative mode
G1 H2 Z10 F4800 ; raise head to avoid dragging nozzle over the bed
G1 H1 X-665 F2000 ; move up to 240mm in the -X direction, stopping if the homing switch is triggered
G1 H1 y-350 F2000 ; move up to 240mm in the -Y direction, stopping if the homing switch is triggered
G1 X4 y4 F600 ; move slowly 4mm in the +X and +y direction
G1 H1 X-10 ; move slowly 10mm in the -X direction, stopping at the homing switch
G1 H1 y-10 ; move slowly 10mm in the -Y direction, stopping at the homing switch
G90 ; back to absolute mode
G1 X50 Y60 F2400 ; put head over the centre of the bed, or wherever you want to probe
G30 ; lower head, stop when probe triggered and set Z to trigger height

Try M561 instead
