home problem for duet wifi 1.04c firmware 3.4 beta2

@massimilianoconti said in home problem for duet wifi 1.04c firmware 3.4 beta2:
randomly sometimes when I bring all the axes home the extruder does not put itself at the right distance x but everything remains at zero and goes to hit the edge of the heating plate
Can you describe for us more details about the problem?
Are you able to reproduce it?
What has happened immediately before the problem occurs? After a print?
Does it home correctly after a fresh power cycle?
Are you able to homeall repeatedly without issue?Can you post your other homing files incase they do something differently that homeall?
Do you use G32/bed.g? Is so, please post it.
If this happens after a print can you also post your slicer start and end gcode?

script start
G28 X Y F4000 ; Home XY
G1 X150 Y150 F4000
G30 ; Probe again to get a more accurate positionYour start gcode is using a different XY location to set the Z height than your homeall and homez.
@massimilianoconti said in home problem for duet wifi 1.04c firmware 3.4 beta2:
G1 X20 Y15 F6000 ; go to first probe point
G30 ; home Z by probing the bedI suggest you change your homeall and homez to use X150 Y150, and then change your start gcode to simply all G28 instead of G28 X Y and then manually probing the center of the bed.

G29 S1Are you actually using G32 at any time? I would suggest you don't use it as it currently is. It's configured to use the old definied point correction, and then loading a saved heightmap on top of it. This would not have a positive effect.
Can you answer some of my previous questions?
-
I misunderstood g32 I only use it when leveling the heating plate and that's it
for holl all and home X home y home z it's okay I put the same coordinates
the other questions that I have not answered what are they? I thought I had more or less answered everything. sorry for the slowness but I don't speak English well.

if i don't use G32 how can i load the dish map?
You can simply send G29 S0 to perform a fresh mesh compensation heightmap creation, or use G29 S1 to load a saved heightmap.
In your slicer start gcode I would suggest simply
G28
G29 S1After changing your homing files you would want to recreate your heightmap fresh with G29 S0 since you've changed the location where Z0 is set.

OK, all right.
I try to answer the questions. the problem I have described to you
it occurs randomly, sometimes after turning on the printer and sometimes as soon as a print starts.
I can not make a video to show you because the problem does not always do, I should be in that moment that manifests itself.
the problem manifests itself like this:
when the machine performs the home all axis, it happens that the extruder after having made X, Y home does not move to the correct position at G1 X20 Y15 F6000; go to first bed probe point and home Zbut it remains at x = 0 and so it hits the heated bed

G90 ; absolute positioningPArt of the problem may be that the X Y distance you have set to move to the endstop is actually shorter than your axis length. It could be possible for it to never hit the endstop. So increase the length of the G1 H1 X and G1 H1 Y moves to be greater than your total axis length. Your homeall uses 305mm for instance.

; Axis Limits
M208 X-20 Y5 Z0 S1 ; set axis minima
M208 X275 Y300 Z270 S0 ; set axis maximaIs this correct that your x axis can move -20mm off the edge of the bed surface before it hits the endstop? It's fine if that is the case.
Is it also correct that your Y axis endstop is 5mm within the printable area? That doesn't seem correct.
-
then I move the Y limit switch to have -10mm from the edge.

I try to make these changes if the problem persists I contact her again. thanks for support
-
hi should be fixed I switched to version 3.4 beta 3, seems not to do the problem anymore
