Did you use a single sheet of paper when it asked, just regular printer paper? Alternatively, if you have some feeler gauges, you can use a 0.10mm gauge. -
@Carlo From my earlier post: When you swapped the original board back in, did you also put the original effector back on, or did it use the smart effector? If you used the original effector (and presumably original probe), can you try that with the Duet? This would at least narrow down if it's the effector or the Duet.

Hi NexxCat
I used the back off a sticker which is 0.1mm on my calipers.
Just found my gauges !Thanks

Hi,
So I used the well 0.102 feeler gauge though it is .10 with my calipers and 3 times got 3 heights.
I did video the whole process but that won't help me
The numbers don't actually help because they are not accurate though one of them is:M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.159 mmI don't think it's the effector because it does what it is supposed to do and no matter what trigger height I put in G31 line its the same outcome and the effector does return the same probe heights all be it not one after the other
maybe the drivers are not calculating correctly I don't know but it is what it is and that is not usable.Cheers for your help.

Ok, last thing I can think of, just to double check if the actual positioning is being repeatable. Run these commands one at a time, or save it as a macro:; Disable any baby-stepping and the bed mesh M290 R0 S0 G29 S2 ; Home the effector G28 ; Heat bed to 60C & nozzle to 130C M104 S130 T0 M190 S60 T0 M109 S130 T0 ; Run delta calibration G32 ; Move the effector to 0,0,Max height G1 X0 Y0 F4500 G1 Z500 F4500 ; Move the effector back to 10mm off the bed G1 Z10 F4500 ; Slowly move down to 0.1mm G1 Z0.1 F600When the macro is finished, the nozzle is at 0.1 on the Z axis. Use the paper or a 0.1mm feeler gauge and see if the nozzle truly is at 0.1mm

Hi Ian,
I used the original effector with the mag arms (printed the adapters) whats funny is I didn't even try to get anything level or square I literally slapped it together set the offset 1 level and it just worked.
I have the effector still wired I can carefully attach it to the Duet2 and try it i cant fit the effector to the other board it's locked down
but I've written this thing off now I don't expect this to ever work with duet but after spending all this time I do want to know whats wrong maybe it will help someone else some day...probably notI post a video of it once its fitted
Thanks

@Carlo
What is your current Z probe offset? -
G31 P100 X0 Y0 Z-0.159
-
@Carlo
I can't remember offhand which way to adjust the offset to bring it closer, but try both of these, one will certainly be too high, but the other, does that give you a 0.1mm gap when running the macro I posted?G31 P100 X0 Y0 Z-0.059 G31 P100 X0 Y0 Z-0.259 -
They have all been tried
it's 0.05 to bring it closer dc42 suggested 0.05 so I've tried all the -0. possible infact the video I posted is -0.05
-
@Carlo
I know you've tried them whilst printing, but try -0.059 and run the macro. Is the gap 0.1mm? -
-
@Carlo
So with -0.059, the gap is exactly 0.1mm after running the macro I posted. Correct? -
Yes spot on 0.1mm
-
@Carlo
Ok, set that in your config. Then create the bed mesh with G29 S0. Once the mesh is complete, try to print the levelling model.I know you've done this so many times before, but let's try now we know the nozzle positioning is correct ok? Use the level_test.gcode I have you before, because I know it doesn't have anything in it to mess with the settings.

It failed but it's too close to the bed just I think but its the best its ever looked.
-
@Carlo
So it was sticking but not extruding because it was too close? Try changing the offset to say -0.1?
