can't upload due to being over permitted size.
Would need to host it on something like dropbox or google drive or even youtube or vimeo.

It doesn't look like you're doing a single G30 before the start of the print. I'm not really familiar with the delta calibration to know if that's still required or not.
-
It is not absolutely required; however, a G32 with a bed.g that does 6 or 8 factor calibration is a best practice.

Based on the video it looks to me that your nozzle is still slightly to high and your printing your first layer to fast, your print moves also seem quite jerky. Have you lubricated the haydn magball ends as he recommends ? https://www.magballarms.com/
-
Hi,
Yes they are well lubricated with a similar dry product which is Teflon based, The trigger height during the video was/is currently
0.05.
I will add slicer settings later once it completes a layer out of interest what trigger height do you suggest ?...as I've tried a few in 0.01 increments
I don't seem to get any false triggers during travel when probing but i'll disconnect the fan during a probe and post again.
I did a G29 S2, G28 then G32 prior to the print.
My bed has G29 S2 added to it and is currently Factor 6 I've tried Factor 8 no benefit/visible effect.; bed.g file for RepRapFirmware, generated by Escher3D calculator

I'll go and move the fan to another socket so I can control it add the M106 and try some more settings again.
So the height will make it complete the arcs which it doesn't at the moment.
So it's just 2 settings move the fan and find a new height .Oh and use the file sliced by another forum user cool...that second one may be a bit trickier now I'm thinking about it ! but hey once more in to the breachAs always big THANKS for the help it really is appreciated I know you don't have to help yet you do.

@Carlo
Try using this macro to configure your Z-probe offset. I wrote it and use it across multiple machines. Make sure to heat both the bed and nozzle. I use 60C on the bed and 130C on the nozzle:;calibrate_z_probe_offset.g G31 P100 X0 Y0 Z0 ; Reset Z trigger height to 0mm M290 R0 S0 ; Reset babystepping G29 S2 ; Clear bed mesh G28 ; Home the effector G1 X0 Y0 Z20 F6000 ; Move close to the bed G30 ; Probe to find a rough Z 0mm G1 X0 Y0 Z1 F3000 ; Move the nozzle to Z 1mm slowly G92 Z3.0 ; Set the Z height to 3mm, allowing moves below 0 M291 P"Lower the nozzle to until it grips a piece of paper. Click to continue." S2 Z1 G92 Z0 ; Define this point as 0mm G1 X0 Y0 Z20 ; Move the probe to Z 20mm G30 S-3 ; Probe and set the trigger height G1 Z20 ; Raise Z to 20mmIt will report your trigger height back, which you can then put into config.g

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 mm2nd
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.146 mm3rd
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.159 mm4th
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.146 mm5th
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.159 mm6th
M98 P"0:/macros/Z probe report"
Z probe trigger height set to -0.159 mmSo 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?
-
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
-
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?
