1. Is there a way to lessen the jagged edges on top and rail here 2. What are these little imperfections on random layers caused by? Also, is it possible to get rid of the stringing?

Is there a way to lessen the jagged edges on top and rail here
What are these little imperfections on random layers caused by? Also, is it possible to get rid of the stringing?

weak quest May 10, 2023, 7:01 PM

#

you can reduce the jagged edges on top by lowering the layer height

#

reduce stringing by calibrating the optimal temperature, pressure advance, and retraction settings for your filament

#

in that order

weak quest you can reduce the jagged edges on top by lowering the layer height

my layer height is .2, what is normal or optimal to print at?

weak quest May 10, 2023, 9:00 PM

#

0.2 is "normal" enough. lowering it will improve the look at the cost of print time

karmic vine May 10, 2023, 9:03 PM

#

#

This was my most recent print, just changed the temp from 200 to 180

#

#

Not too happy about the top of this stack, but i assume that's a layer height thing

weak quest May 10, 2023, 9:04 PM

#

that looks like part of the reason it's so ugly

#

please attach the gcode

#

looks pretty good. you currently have external perimeter acceleration set to 1000, you could try 500 to maybe clean this up a little

#

what printer is this? it's a pretty good print

karmic vine May 10, 2023, 9:09 PM

#

it's the anycubic kobra plus

#

I just got it set up yesterday...it's definitely a learning process

#

#

would that be this? or all of them that are at 1000>500

weak quest May 10, 2023, 9:12 PM

#

up to you. lower will give you better quality, at the cost of print time

#

you could also Increase the acceleration for the infill probably, to improve print time

#

I don't know what that printer can handle tho

karmic vine May 10, 2023, 9:14 PM

#

is this controlling how fast the nozzle moves?

#

or the print head, rather

weak quest May 10, 2023, 9:17 PM

#

this is the acceleration, how quickly it gets up to speed

karmic vine May 10, 2023, 9:19 PM

#

if I were to try a smaller layer height, what would you suggest going down to?

weak quest May 10, 2023, 9:22 PM

#

0.14 maybe? look at the gcode preview in your slicer before you print to get an idea of what it will look like

karmic vine May 10, 2023, 9:25 PM

#

What does the red/green/yellow tell me in the preview

#

weak quest May 10, 2023, 9:26 PM

#

depends on what view you have it in. look at the legend.

#

looks like you have it "feature type" mode or whatever

karmic vine May 10, 2023, 9:28 PM

#

Ohh ok I see now

#

#

Are these lines on the floor preventable?

weak quest May 10, 2023, 9:32 PM

#

the pink or the red?

karmic vine May 10, 2023, 9:40 PM

#

the pink

weak quest May 10, 2023, 9:44 PM

#

oh, it looks like you have retractions completely disabled?

#

no, just kidding, it's just not retracting there

#

also, semi unrelated. you want this on for a better surface pattern

#

I think the "pink" issue is you need to turn on "Retract at Layer Change"

#

that line is the travel from one layer to the next

karmic vine May 10, 2023, 9:49 PM

#

ok that makes sense. I will try a new print with your suggestions unless you see anything else right off

weak quest May 10, 2023, 9:50 PM

#

the infill pattern you have chosen (or not chosen) isn't necessarily the best

karmic vine May 10, 2023, 9:52 PM

#

yeah, that was the default, which is best?

weak quest May 10, 2023, 9:53 PM

#

there's tradeoffs with a few of them. but the "3d" ones are generally uniformly stronger, not that it really matters for this print.

karmic vine May 10, 2023, 9:53 PM

#

#

the cross 3d?

weak quest May 10, 2023, 9:54 PM

#

no. that's a weird one. I guess Cura doesn't organize them by 2d/3d

#

gyroid is what a lot of cool people use (and it's what I use) but it can slow down the print if your acceleration isn't cranked up a lot

#

it's a lot of back and forth movement

karmic vine May 10, 2023, 9:58 PM

#

it definitely looks cool 😎

#

it only added 2 minutes to my time I think

weak quest May 10, 2023, 9:59 PM

#

😎

karmic vine May 10, 2023, 10:00 PM

#

I guess I'll be cool too

weak quest May 10, 2023, 10:00 PM

#

yeh

karmic vine May 11, 2023, 12:26 PM

#

#

#

Ok so it's pretty good but now I dont understand where the stringing is coming from

karmic vine May 11, 2023, 1:34 PM

#

#

I broke the one side off but you get the picture

karmic vine May 11, 2023, 3:01 PM

#

#

#

seems like it's happening on the seam

#

would tweaking pressure advance settings help this? I'm trying to print a calibration cube now

weak quest May 11, 2023, 3:54 PM

#

karmic vine would tweaking pressure advance settings help this? I'm trying to print a calibr...

yeah, tuning temperatures, pressure advance, and retractions could help

#

enabling "wipe" in your slicer might help

karmic vine May 11, 2023, 4:45 PM

#

this?

#

I was looking at how to do pressure advance but can't really find a good tutorial video for cura, they talk about tweaking the code but idk how to get to the code

weak quest May 11, 2023, 8:08 PM

#

no. outer wall wipe or something

#

pressure advance is not something done in the slicer

#

Are you using klipper or marlin firmware?

#

marlin calls it "linear advance" and marlin has a guide for that.

#

klipper calls it pressure advance, and they have a guide for it too

karmic vine May 11, 2023, 8:42 PM

#

I did it in clipper but idk if it even worked

#

#

it looks like the best one is 0...which is off.

#

so I have no idea

weak quest May 11, 2023, 8:44 PM

#

are you running klipper firmware?

karmic vine May 11, 2023, 8:47 PM

#

oh wait, I think it's marlin

#

https://marlinfw.org/tools/lin_advance/k-factor.html

Marlin Firmware

Linear Advance Calibration Pattern

Create G-code to calibrate LIN_ADVANCE setting

#

I was doing this

#

but earlier I did put the klipper plugin on cura

#

#

this is what it looks like in cura, but idk where to get the values. I really didnt want to print this huge box

#

#

I attempted to print something earlier and this is how it was coming out

#

weak quest May 11, 2023, 9:00 PM

#

karmic vine

this what you should use for marlin. what speeds did you choose?

karmic vine May 11, 2023, 9:02 PM

#

weak quest May 11, 2023, 9:06 PM

#

kinda looks like linear advance isn't being applied. I wonder if it's not enabled in your firmware. that's unusual these days though

karmic vine May 11, 2023, 9:13 PM

#

how do I check in my firmware?

#

none of the tutorials I've watched have actually said how to get into the firmware or how to modify it

karmic vine May 11, 2023, 9:43 PM

#

none of this is really making sense to me...

red inlet May 12, 2023, 12:05 AM

#

karmic vine

the bumpy thing is the layer change

karmic vine May 12, 2023, 12:06 AM

#

Yeah, I understand it's happening at the layer change but I'd like to minimize it

weak quest May 12, 2023, 12:10 AM

#

enabled outer wall wipe?

karmic vine May 12, 2023, 12:48 AM

#

I couldn't find that in cura...I have a print going so we'll see how it turns out

weak quest May 12, 2023, 12:51 AM

#

the settings have a search box

karmic vine May 12, 2023, 12:42 PM

#

#

it was on for the print

can you show the preview page
