Another Predator

Carlo

Really appreciate your help and well everyone's help to be honest
That file prints fine on my linear plus and ender3

Try printing that. It contains my startup code, the calibration of the printer, the prime line, and a single layer 40x40 square.

Unless things are going really wrong, let it finish and take a picture. Obviously if it starts to make a real mess, stop it and photo that instead

You will need the web UI open as the calibration has a user prompt to make sure the nozzle is clean. Lastly, are you cleaning your bed with anything? If you've got isopropanol alcohol handy, give it a wipe with that whilst cold.

@NexxCat

Thanks for this I'll try that now...Yeah I clean it with brake cleaner ..acetone I'll clean it first and always have to wipe the nozzle.

Thanks

Carlo

@NexxCat

Ok ....

Looks great

NexxCat

@Carlo
Well that was unexpected Can you take a closer picture of the square it printed if possible please?

Carlo

@NexxCat
Yeah of course here we go its off center ...shadow

NexxCat

@Carlo
That looks pretty decent, so, hm, I wonder if I could try slicing the bed level STL for you, add in my start code and see what we get? Do you have a link for the STL?

Carlo

@NexxCat

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.

NexxCat

@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

NexxCat

Here you go: LEVEL_TEST.gcode

Carlo

@NexxCat

I'll print that now ..Thanks.

Carlo

@NexxCat

Hi,

Ah bugger It failed

NexxCat

@Carlo
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.

Carlo

@NexxCat

Thank you appreciate the help

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?

Carlo

@Phaedrux

Hi Phaedrux,

It's not tight cabling picture above a bit deceptive ..

Thanks

Phaedrux

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

Carlo

@Phaedrux

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.
