Sorry I'm trying to find the file I downloaded is thingiverse down ? or have they done a big update ? I can't find any predator stuff.
-
@Carlo
They've been doing updates all day and have broken stuff on and off throughout... So I guess business as usual at Thingiverse?
Let me see if I can find it
EDIT: Found it, slicing it now
-
Here you go: LEVEL_TEST.gcode
-
I'll print that now ..Thanks.

Damn =\ Well we know it can print properly in the middle, so I'm wondering if it's a issue with the bed mesh or something else. I can't help more tonight but I'll have a ponder and come back tomorrow, maybe someone else has an idea based on what we've discovered. -

Is it just me or does the bowden tube look quite taught in that photo? Is it possible that the wiring harness/bowden tube is pulling on the effector when it's at the edges?

I still think the bowden tube looks taught, but you're the one with eye balls in the room.

Hi,
The extruder is suspended via springs so the bowden will flex as the effector moves but this is the standard setup for this printer and the same setup which prints with the original board .i.e. it's not stopping the nozzle from reaching the extremities of the bed infact the bowden is longer than the standard supplied bowden as I didn't like it flashing the trigger on movement now it doesn't flash unless it's probing.
I have also probed without the bowden or filament attached with no more success than I have now.
Hope that explains it.Thanks

I put my nimble V2 back on hoping for better luck....nope exactly the same and I've tried well basically all trigger heights with no joy.....I previously asked if it could be sent back the board and effector (refuse to call it smart at this point)to be tested but never received a response ?
As a few people on these forums have this very setup working but no matter what I try I get the same result even when the kind forum users with this very setup slice files and offer settings that they themselves use successfully on the same machine yet I get no change what so ever....everything on this machine is new and the only part that does change and succeed in printing is removing the Duet2 and slapping in the original board.....what does that say ?Cheers

@Carlo Sorry this has been such a frustrating experience for you. 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.
If you didn't swap back the effector, the only thing that I can think of is to try a 'manual' probe setup. Replace the probe type in config.g with type 0 (eg M558 P0 H5 F120 T6000), then run through a bed calibration and start a print. It should ask you to manually step the Z down at each probe point, until it touches the bed (use a thin piece of paper, babystep the Z down until it just grabs the paper under the nozzle). You may want to reduce the number of probe points!
Then proceed to run a print in the normal way. If you home and do G30 to set Z height, it should ask you to manually do that, too.

This is the result I think everyone looks and thinks it's too far from the bed but it's not actually completing the print move it's changing direction before it should in the picture you can see where the print does a U turn on it's self so it never joins the print together it just doesn't complete the move almost like the radius is wrong like the circle is smaller than it is I'm watching it and it does not complete the circles or arcs it never makes it to the end it changes direction and doesn't go back to finish it.
If you are still having this problem, can you post a video of it printing, to show what you mean?
What filament are you using, what is the bed surface, and what bed temperature?

Hi Ian,
Not your fault I appreciate all the help everyone has offered ...still hoping its my fault.
I did do a manual probe as suggested didn't make any difference.

Hi dc
If you are still having this problem, can you post a video of it printing, to show what you mean?Yes still having the same problem.
What filament are you using, what is the bed surface, and what bed temperature?Ultrabase PLA 70c.
I have shot a video just now but error can't upload due to being over permitted size.
Cheers

Would need to host it on something like dropbox or google drive or even youtube or vimeo.

No worries thanks

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/
