Thanks I'll try that right now.
Really appreciated.

Hi,

I ran the macro thanks for that results are:

1st
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.084 mm

2nd
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.146 mm

3rd
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.159 mm

4th
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.146 mm

5th
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.159 mm

6th
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.159 mm

So not sure what to set it to ... I know -0.159 I thought 3 out of 6 gotta be the one ....Its not the one.

Thanks for the help oops guys or Ladies really appreciated PC correction

I can't remember if this has been asked already, but has the bed been PID tuned?

Carlo

@Phaedrux

Hiya,

Yeah both H0/H1 have and they are in the config.
I'm calling it now..... I'm done off to research a replacement.

Really appreciate all the help from everyone big THANK YOU!

@Carlo
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

Carlo

@NexxCat

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 mm

I 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.

@Carlo
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 F600

When 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 not

I post a video of it once its fitted

Thanks

Carlo

@NexxCat

I'll do that now.

Cheers

@NexxCat

Hi NexxCat,

No its 0.1mm to high

NexxCat

@Carlo
What is your current Z probe offset?

Carlo

@NexxCat

G31 P100 X0 Y0 Z-0.159

NexxCat

@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

Carlo

@NexxCat

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

NexxCat

@Carlo
I know you've tried them whilst printing, but try -0.059 and run the macro. Is the gap 0.1mm?

Carlo

@NexxCat

Doing it now

Bang on

NexxCat

@Carlo
So with -0.059, the gap is exactly 0.1mm after running the macro I posted. Correct?

Carlo

@NexxCat

Yes spot on 0.1mm
