Another Predator

@Carlo
Have you re-sliced that bed level print, or are you printing the gcode that came with the predator?

Carlo

Hi,

It's re-sliced and I have one sliced by another user on these forums they are both the same in fact all prints are the exactly the same.
I wanted to rule the file out so another one of you extremely helpful users kindly sliced it for me to rule the file out for my own sanity.

Give me a few minutes. I'm going to craft a gcode file for you to run, based on my startup settings and prime line. If you want to try that, we'll see what happens?

Carlo

@NexxCat

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

Cheers

Test.gcode
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

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