#How to get rid of these artifacts and have more accourate prints

I would like to know if you have any tips on how to make my printer a bit more accourate
Screws tightened
PID tuning
E steps calibrated
Linear advancing
Set jerk from 10 to 7
Tried playing with extrusion rate
XYZ steps calibrated
Result is what you see on the photo, although it is indeed upgrade from what it used to be, i would like to know how to get rid of the round edges and those "artifacts" next to the letters on the cube

AI Help

Based on the information you provided, it sounds like you have already taken a lot of the necessary steps to improve the accuracy of your 3D printer. However, there are a few additional things you can try to get rid of the round edges and artifacts next to the letters on the cube:

  1. Check your nozzle and extruder: If your nozzle or extruder is worn out or dirty, it could affect the accuracy of your printer. Try cleaning your nozzle and extruder or replacing them if necessary.

  2. Use thinner layers: Printing with thinner layers can help improve the accuracy of your printer, especially when printing small details. Try reducing your layer height to see if that makes a difference.

  3. Adjust your print speed: Printing too fast can also affect the accuracy of your printer. Try slowing down your print speed to see if that helps eliminate the artifacts.

  4. Calibrate your bed: A level and well-calibrated bed is essential for good adhesion and accurate printing. Make sure your bed is lev...

Did you calibrate your flow?

#

I also wouldnt adjust your xyz steps most people are just doing it comepletley wrong

E-Steps is not flow

forest stirrup
#

it’s flowing differently at slower speed than at higher

ebon mortar
#

And you should adjust your e-steps first andan do flow

forest stirrup
#

Had this issue before

#

Just used klipper for the pressure advance but if ur marlinated rn it’s called linear advance

unkempt hearth
#

then i tried to play with this and didnt help much

#

maybe u did it weird

#

wait

#

ur filament is being too fluid

#

play with flow in the slicer

#

wait no now I’m confused

#

it looks fine looking at it again

#

i think it just has cleaner corners when it wasn’t already turning

#

check for wobble tbh

unkempt hearth
#

aight i may have an idea

#

just have to wait until the cube prints again

#

i think i made M900 command wrong

#

if so the linear advancing didnt work

With Acceleration, Linear Advance and Input Shaping, be sure to do the tests at your normal print speed

unkempt hearth
#

i didnt try input shaping and acceleration tbh

kind frigate
#

More often than not Acceleration is best at stock values, input shaping though can remove little artifacts you have

#

when it comes to the rounded corners though, you gotta tune Linear Advance right, be sure to use your normal speed and printing temperature

unkempt hearth
#

are these values acceptable ?

image.png
#

acceleration is turned of if i understand correctly

kind frigate
#

I can't read that 😅 and I don't use Prusa Slicer to know what it is by it's position

unkempt hearth
#

aight gimme a sec

kind frigate
#

Your speeds are good, they are actually on the slower side so you can go faster and expect relatively same quality, only thing I'd comment on is support speed, I tend to print that slow (Less or equal to 30) so it doesn't fall apart

unkempt hearth
#

i have pretty strong supports.... way too strong for my liking sometimes 😅

#

tried to set jerk down to 5 and result is not very different

kind frigate
#

I don't have much experience with Jerk settings, I've mostly used Junction Deviation instead

unkempt hearth
#

also this should be correct syntax yes ?

image.png
kind frigate
#

Why not just save it to your EEProm?

#

It is however the right Syntax yes

unkempt hearth
#

some1 told me its better to have separate K value for every filament since it may vary

kind frigate
#

Ah, Filament GCode

#

I only saw the "Start G-Code"

#

yes that would make sense

unkempt hearth
#

i mean i just ran g code for determining K value, decided that straightest line is the one with 0.6 value and that was it

#

how often do you change belts on your machine ?

kind frigate
#

Depends on the quality of it I guess? I haven't had to change the belts on my printers yet other than 1 that snapped on me

#

I have ordered some Gates belts that should be arriving in a week though and I will replace the belts on all my printers, but till this point, I haven't had to replace to do them being worn out or something

#

How long have you had your printer?

unkempt hearth
#

over a year now i guess

#

wasnt printing for a while though

#

didnt find anything wobbling thoug

kind frigate
#

Do you have belt tensioners?

unkempt hearth
#

nope its tightened from assembly

#

sent a vid

#

should it be tighter ?

kind frigate
#

Maybe someone with more experience with belts can comment on that, mine are usually tighter than that and I personally feel as if its not possible to tighten it enough before assembling, as it won't be possible to assemble it if its too tight (because of the way idlers and pulleys are designed with a lip), but I don't really have "proof" for that other than it makes sense to me

#

Also, since you are using Linear Advance, I assume you are using a TMC driver?

unkempt hearth
#

stock ones

#

not sure what those are

#

but i wanted to buy TMC2208 iirc

#

though i heard that they dont like linear advancing so im not sure ill buy these

Is it custom firmware that you have running on it?

unkempt hearth
#

ill check

#

form here

#

Marlin-Ai3M-v1.4.6-stock one....got me rid of that annoying beeping noises😅

kind frigate
# unkempt hearth but i wanted to buy TMC2208 iirc

You'd have to ask in #hardware to be 100% sure but IIRC TMC2208 used to not work with Linear Advance (when Stealthchop is Enabled?) in older versions of Marlin, but that has been solved, and it is best to use Spreadcycle on extruder rather than Stealthchop with TMC2208

#

I currently am running Linear Advance on TMC2208 (in standalone mode) with linear advance

#

but I do recommend just going with the TMC2209

unkempt hearth
kind frigate
#

But if your board doesn't have "plug in" steppers than you'd have to get a whole near board alltogether

#

I'm honestly not sure if yours is TMC2208 or A4988, seems theres versions for both but idk which is in your printer

#

idk how well Linear Advanced works on A4988

unkempt hearth
#

well

#

gimme a sec ill run the linear advance code again

kind frigate
#

I personally prefer Linear Advance towers since you can see how it looks on an actual print

unkempt hearth
#

those exist ?

#

i just used the code from marlin

kind frigate
#

Yea, I prefer them over the ones from marlin cause its hard to see and sometimes I had issues with weird bulges that wouldn't go away no matter what value I used

unkempt hearth
#

Here

#

Although maybe 1 looks best now

#

What do you think?

kind frigate
#

You have to do the test multiple times

Watch this (you can skip to 7:30)
