Kossel Delta xxl build project HELP

If you previously set the homed height correctly as I described, using paper and G92 to set the Z0 should never be necessary.

I found that if I home the printer, then issue G32 from there, it goes incredibly slow.
So I prefer

Home the printer (G28)
Move to 5 mm above the bed. (G0 Z5 F1800)

Heat up the bed to 60C and the Nozzle to 130C
Make sure nozzle is clean

Use Z Probe to more accurately find bed position (G30)
Autocalibrate (G32)

Then I don't home the printer again

I manually move the nozzle up a little bit
Heat the bed up to what it needs to be at for my material
Then I heat the nozzle up to what it needs to be at for my material

Clean the nozzle again
Then print my gcode

(My Slicer start and end gcode don't have G28, but my end does move the carriages back up to just under the endstops. I also have not added any G28's anywhere in the .g files on the Duet)

Thank you FA-MAS. I did exactly what you said. When I sent G 32 the nozzle is not touching the all points and I got this error : Z probe already triggered at start of probing move. Compensation or calibration cancelled due to probing errors.

The G30 prior to it worked without an issue?
With that error, it would seem to me that it thinks the probe is already triggered. What's the Web Control say for Z Probe when it's idle some height above the bed?

Now I sent G28 and G0 Z5 F1800. All good. When I sent G30 the nozzle is not touching the bed and if I keep sending G30 the nozzle is going up.After I sent G0 Z5 F1800 the Z probe on the web Control is blinking a few times 1000 then is 0

Would you post your complete config.g, homedelta.g and bed.g files?
Sounds like it thinks it's triggered already, i wonder if it's considering itself being at Z0 already and then moving up to what it thinks is Z5 in relation.
Generally the Web Interface should say Z Probe is 0 when it's not triggered, and usually it's 1000 when it's triggered.

That all looks right to me, what's the Z Probe reading on the Web Interface?

I noticed right now when from home position I sent the G0 Z5 F1800, on the way down to the bed the web Control it says 0 then a few times 1000

I homed again and G0 Z5 F1800. Web Control is 0 and the PanelDue : Z5
Also when the printer is homed PanelDue should be Z465, now is 462.91. I have the homed hight in Config.g set to H470

There's not a G92 in any of the other .g files is there?

I never looked. Where I should check ?
I don't have any G92

Edited 1 time(s). Last edit at 06/05/2019 01:02PM by alex773.

Maybe check any of those .g files you might have modified? Possible a G92 was intentionally left in one of them?

I wonder, if you home the printer and then move the nozzle down manually using the web interface buttons, are you able to manually get the nozzle to lightly pinch a piece of paper between the nozzle and bed?

I moved the nozzle down to bed but it stopped 2mm, 3mm above the bed. Could be the difference between Z465 to Z462.91 ?

Edited 1 time(s). Last edit at 06/05/2019 01:18PM by alex773.

Power it off completely, then back on and try again, I wonder if it's got the homed height still in there from previous autocalibration.

Power off and then on and the web Control is Z0 and the PanelDue is Z470. If I homed again the PanelDue is Z465

I believe that's normal, you probably checked during the time before the Duet has updated the info on the PanelDue.
As long as you home it, it triggers the endstops and moves down 5 mm, then both read Z465, it should be good

At that point, see where G0 Z5 F1800 gets you, it should be close to 5 mm away from the bed
See if you can manually move the nozzle closer to the bed, say 1 or 2 mm away
If you can do that, then G30 should work

After G0 Z5 F1800 I moved the nozzle down 2mm, then I sent G30 and G32 and it worked.

You don't have to move the nozzle down the 2mm in the future, just testing to see if it would be able to move lower than what it thought was Z5

So the best is to have in my Slicer No G code on Starting script. How about the Ending script ? I know you have in Starting script to have the nozzle extruding some filament. What do you have in Ending script ? Could you please help me to set up my Slicer ?
This is what I have in Ending script
:M104 S0 ; turn off extruder
M140 S0 ; turn off bed
G28 ; home axes
M84 ; disable motors

Edited 1 time(s). Last edit at 06/05/2019 02:26PM by alex773.

Definitely remove the G28 from the end gcode I'd say replace it with G0 Z464 F1800

I would also remove the disable motors line
You're not going to be moving them by hand, if you did, calibration would be off
And it doesn't hurt to keep them on

For the start.gcode

I do all the stuff I posted earlier manually when I turn on the printer, then I don't have to do it again until I turn it off
It's so quick, I just type the commands in

For start gcode all I have is.

G0 X0 Y-149 Z25 F1800 ; Move nozzle to center, forward off the bed and 25 mm from bed.
; Leaving space to prime the extruder.
G0 Z[first_layer_height] F1800 ; Move nozzle to first layer height.

That's all, I leave my skirts to 3 loops, 6 mm away from the object and that primes the extruder

You can leave all the stuff like turn off the bed and extruder,

I updated. Now the Starting and Ending scripts are the way it should be ?

It’s all kind of preference. That’s essentially what I have in mine, you may find in the future that you want it to do something else. It should get you printing though.

Thank you so much FA-MAS.

I'm trying to print a small cube and I turned on the printer, G28, G0 Z5 F1800, G30 and G32. When I run G32 I got this error : Z probe was not triggered during probing move. I don't know what I'm doing wrong. G32 it's not working, it is not probing all the points. Is just not working. Something isn't right

Edited 1 time(s). Last edit at 06/05/2019 04:32PM by alex773.

G30 works ok, but then some points on G32 give that?

Yes. G30 works ok , only G32 is not probing.
It drives me crazy
