Problem by printing xyz Cube

Veti

@lui2004
check that there is a G28 in the beginning of the file. thats all that is required for the bltouch if it is set up correctly

also to rule out a setting mistake, give another slicer a go like prusaslicer.

lui2004

@Veti ok i will try once again to define pressure advance

i will try another slicer

lui2004

i got my value now its 0.166

so i insert it in my config.g like this:

M572 D0 S0.166 ; Pressure Advance

how can i test this now? benchy ?

print the same thing as before

lui2004

@Veti ok will reprint the xyz-cube

lui2004

So i have reprinted the Cube

It is much better but not perfect all sides have 20x20x20 almost perfect

Veti

the corners are round.

grab the cold nozzle with your finger. see if you can displace it easily (we are talking about milimeters here)

lui2004

@Veti i can Move it and its not to hard and not to easy

Veti

@lui2004
sorry forgot to add, while the motors are energized?

check the eccentric nuts. the there should be no play, but also the wheels should move easily.
also the belt tension should be like a bass string when you pluck it.

lui2004

@Veti no,with power off.

I will test it later

Thanks a lot for your pacience

lui2004

@Veti i have checked all belt tension x and y and the accentric nut has no play.

i print the cube again and post the results

other strange is S3D show me the exact,what i am print

here a screenshot:

@lui2004

as i dont have s3d, why dont you give prusaslicer or cura a go?
lately i have switch from cura to prusaslicer, as its gotten really good.

@lui2004

Those are the retractions, maybe trying increasing the length? Ender 5 is a bowden setup right?

lui2004

yeah i think after i print the cube
i will try the alpha prusa slicer ,i heard its much better now

lui2004

@Rushmere3D i have install as DD

Rushmere3D

@lui2004 Oh OK, I'd suggest trying at least 0.8mm up to 1mm and maybe reduce the retraction speed to 45mm/s.

for tuning the seam it's usually best to force it to a single spot. But it really depends on the model you're printing. If the model has a lot of details and inner corners the slicer can hide the seam a lot easier. On cubes and cylinders it only has external faces to put them where they are obvious. Try printing a more complex model. Your cube looks good. Move on to a benchy or something.

I have order a new Nozzle ( Plated Wear Resistant All Metal MK8 ), now i am waiting for to test.

i will inform you here

Veti

@lui2004
what material are you printing that requires that?
