Meal, I converted an Ender 5 plus so far so good, but from about layer 10 onwards the nozzle only scratches the print. I'll send a picture with it Config Btt Octopus 1.1 Z spiral left and right slope unknown is the originals Z engines are also still original The flow is also set so that I have a perfect first layer

plus_only_bed_raiser_2.stl
plus_only_bed_raiser_3.stl
plus_only_bed_raiser_4.stl

#

probably too much flow

shy marlin
#

No flow is perfect

grave osprey
#

Might also be a config issue

#

What's your z rotation_distance

shy marlin
#

I send my confit

if you tune your flow according to your first layer, it is not perfect
cause how do you know your first layer height is perfect without tuning flow first?

#

I'm on mobile, so just a screen shot of the z section would be best

#

Or copy and paste the section

#

I messure my walls out we got a macro fot flow calibration

grave osprey
#

Stock lead screws?

shy marlin
#

Yes

#

The full bed is stock

grave osprey
#

Home z and move the z to 50mm and measure of its 50mm

shy marlin
#

Okay wait

grave osprey
#

It will either be close to 50, 25, or 100

shy marlin
#

71 is homed

#

121 is - 50

#

Is perfect

#

I try to send you a video

winter tinsel
#

can you also provide a picture on how a printed object with that problem looks?

shy marlin
#

Yeh wait i print it give me 10 sec

winter tinsel
#

yeah, that's too much flow

#

like way too much

#

steps for tuning your printer:

  1. general leveling
  2. rough z-offset so small stuff at least somewhat sticks
  3. flow calibration
  4. more precise first layer height
  5. temp tower
  6. might need another flow test cause of different temp
  7. precise first layer height
  8. pa and stuff

At least that's how I handle it and that works prefectly fine (also makes sense if you think about it)

I use flow Multiplier calibration

grave osprey
#

I tune flow based on. Top surface finish

#

Works much better

shy marlin
#

Yeah i messure this

#

Must be 0.7571

#

I do a new one

#

I did the same test with a anycubic vyper an its perfect
