Seams are a bit all over the place due to incorrect settings in the slicer 😄

3D Benchy, 140mm/s, 5000mm/s accel. Marlin Input Shaping, LinearAdvance, Stock Ender 3 Pro

[woeful echo]

linear advance on stock board?

[quaint saddle]

@woeful echo yes, fixed since 2.1.0 or 2.1.1 AFAIR

@strong cobalt how long did the print take?

thats a very respectable benchy

[woeful echo]

oh cool

[strong cobalt]

Yes

[strong cobalt]

Due to Linear advance about 1hr

[quaint saddle]

LA should not have that effect

[strong cobalt]

The stock bowden extruder can only handle a factor of 0.8, it accelerates to slow to reach the speed all the time

[quaint saddle]

I see

[dark pebble]

You should be able to go much faster

[lucid girder]

You have a guide on the marlin input shap and linear advance?

[quaint saddle]

Linear advance: https://ellis3dp.com/Print-Tuning-Guide/articles/pressure_linear_advance/introduction.html

input shaping: Print input shaper sample, measure distance in ripples, set frequency

but also see https://marlinfw.org/docs/gcode/M593.html

[lucid girder]

thank you

[strong cobalt]

with bowden ?

[dark pebble]

yep

bowden should be wayyy faster than direct drive

[strong cobalt]

well 0,8 is one line for me, the other lines look wonky in the calibration print

[dark pebble]

i got a 32 min benchy on my direct drive setup with a much bigger bed than yours

[strong cobalt]

or do you mean mm/s speed not LA

[dark pebble]

LA shouldnt affect print speed that much

[strong cobalt]

the 0.8 factor is pretty high

if i turn LA off it gooess brr fast 😄

[dark pebble]

i would try to do the 32 min benchy again but i cant cuz i dont have my blower

[dark pebble]

oh yeah

you should look into converting it to direct drive

[strong cobalt]

i know im about to print a direct adapter 😉

lol 2x guys same thought

[dark pebble]

xd

yeah no direct drive is a blessing

[strong cobalt]

yeah but the problem is my CR touch is in the way all the time

[dark pebble]

the cr though shouldnt stick out that much

btw this is my toolhead

[strong cobalt]

140p cant see much sorry 😄

[strong cobalt]

im about to print this this doesnt get int to stock cr touch holder way

[dark pebble]

alr

[strong cobalt]

https://www.thingiverse.com/thing:4935601

think this is good?

it goes behind the x rollers

[dark pebble]

yep it should work

[strong cobalt]

allright

but i have another problem, my PTFE tube doesnt come of the hotend 😂

[dark pebble]

heat it up and remove it

heat it up to around 220

and pull it out

[strong cobalt]

well doesnt matter ill cut it from the hotend as long as i need it 😉

[strong cobalt]

this is with LA on, https://streamable.com/a3y4ox

[dark pebble]

icic

[strong cobalt]

0.8 is like printing 30mm/s 😂

[strong cobalt]

i think i gonna print it like this

[dark pebble]

yep

thats the correct orientation

[strong cobalt]

2 hrs 😄

[strong cobalt]

how did you achieve a 32min benchy?

[dark pebble]

well i did it with no lin adv

but i just cranked the speeds up and letterip

[strong cobalt]

aight
