Ender 3 Max print head too high.

[scenic otter]

This is my print head when adjusted with the knobs and auto home

And here it is mid print

@limber forge

I can take more pictures if you would like aswell.

[limber forge]

that might be an issue with your slicer settings actually

what's your z offset in the slicer set to?

[scenic otter]

I don't know how to check, I'm using Creality Slicer. Should I use something else?

[limber forge]

use cura

the creality slicer is basically just cura with some other stuff that creality put in there

but basic cura gets faster updates and has less issues so just stick with that

[scenic otter]

Alright, great. Do slicers just make 3d models into instructions for the printer?

Always wondered what they did

[desert mango]

is the z endstop too high?

like when you home it the printer is a few cm too high?

[limber forge]

if the z endstop was too high it wouldn't print the line on the left

[scenic otter]

Nope, it is right were a piece of paper can fit in.

[limber forge]

and that part prints fine

that's what makes me think its the slicer, because the offset changes in the gcode from where it prints the priming line to when it prints the part

[scenic otter]

Alright, I've got cura installed. Where do I configure the offset?

[limber forge]

the default should be 0 (which is fine)

just use cura's default ender 3 max profile and slice and print from there and see if it works

[scenic otter]

Alright, and just this option aswell?

[limber forge]

yeah save it to the micro sd card that came with the printer

[scenic otter]

Dont see a clear "slice" option like creality 😅

[limber forge]

what file did you put in there?

it should be an stl file not a gcode file

[scenic otter]

Oh, sorry I accidently put my old gcode in instead.

[limber forge]

understandable lol

i could tell because of the "no time estimation available"

[scenic otter]

Yea, I was wondering if it just auto sliced. Well, brb lets see if it works!

No dice, unfortunately.

[limber forge]

about how far is it from the bed?

[scenic otter]

I can measure if you would like.

[limber forge]

did you level the whole bed? it looks kinda slanted compared to the gantry

[scenic otter]

Yea, I did turn the bed by approximately the same amount of turns. I could try fully tightening it and doing a manual adjust on the printer it self?

[limber forge]

walk me through how you leveled the bed, I think you might have missed some steps

[scenic otter]

Sure.

So first step,I tighten all the knobs just until I feel resistance and then I stop.

Next, I place a piece of paper where the extruder would come down. Then I slowly tighten every single knob by the same amount of rotations until I'm happy with it barely touching the paper.

The manual says scratching the paper, but I've found that low to also scratch up the bed

[limber forge]

yeah you forgot the "repeat" step lol

that part's right, but you're supposed to do that, then move the nozzle to another part of the bed, and do it again

so start at the homing corner, move just that leveling knob till you feel resistance on the paper, then move it to another corner, then move that leveling knob, then the next corner, and so on

[scenic otter]

Ahhhhhh, I see.

[limber forge]

then after that go back around just to check everything

[tranquil wind]

@scenic otter check your start script there is a high chance that your auto bed level is off it you have one

[limber forge]

since usually when you move one knob it'll mess with the height of the other knobs too

[scenic otter]

How would I do that?

Just open my gcode file?

[tranquil wind]

do you have autobedlevel?

[limber forge]

you don't have an auto bed level so that wouldn't apply to you

[limber forge]

stock e3 max, no leveling

[scenic otter]

Oh alright, thanks anyways.

[limber forge]

https://www.youtube.com/watch?v=_EfWVUJjBdA here's a vid on how to level it

[tranquil wind]

okay then forget what i said

[limber forge]

he starts using some fancy sticker thing but just use paper

he also uses a gcode file to facilitate the movement (you could use it, but its not necessary), you can go into the control menu, go to move axis, move 10mm, and just move it around through that

the e3 max has a 300x300mm print bed, so that's around where you should put it to go to each corner

the autohome corner is 0, 0, close right is 300, 0, far right is 300, 300, and far left is 0, 300

[scenic otter]

Alright thanks alot for the vid! I'll level and check back.

[scenic otter]

QQ: after playing with it for a while I keep running into an issue of my left side being perfectly fine but my right side has wayyy to much of a gap to use the adjustment knobs

Ive tried moving around the z switch, but then the issue seems to reverse

[scenic otter]

Hey still having issues w this, anyone got an idea ? ^

[desert mango]

personally i'd move the z endstop until i found a spot close enough to the median, then i'd use the set home offsets to offset the z by a perfect amount in between the two sides of the bed, that way one can loosen and the other can tighten and it can be as close as possible

[scenic otter]

I'm using some rubber stoppers in-between the screw and spring, would that be fine? Seems to give me the hight I need.

Added the equal amount to each side, and tightened the ones that needed it

[desert mango]

yeah if it works then do it

it would just be bad if over time it deformed but i dont think its under that much pressure

[scenic otter]

Yea, I got it decently leveled. Now I just have issues with some squiggly lines so I'm fine tuning it

[scenic otter]

Hey @desert mango , I think I got it decently level. I keep running into these wavy lines printed tho, causing some lines to be fat and get caught when the printer comes back around. What should I do?

Spent 2 hours making this, 2 days leveling it 😭😭😭

[limber forge]

can you show a picture?

its likely just slightly too close

[limber forge]

that is really unusual

it might be a partial clog

I've never seen that before

[scenic otter]

Mabye? I've had it run for a couple seconds when the printer bed was too high so it was just extruding.

Anyway to get the gunk out?

[limber forge]

there should be a thing that came with the printer for it

its a thin metal rod that has a springy thing on one end and a foam block on the other to protect the tip

the springy part is the handle, you just heat up the printer and shove the needle thing in the nozzle

that should clear it

[scenic otter]

Hm, myn didn't come with one. Would a thin needle and a piece of cloth do the trick?

[limber forge]

it's a 0.4mm nozzle, the cloth wouldnt fit and I doubt you'd have a needle that thin (if you happen to have one though its worth a shot)

the needle thing should look like that if you have it

if you wanna double check if its a partial clog though just run some filament through the nozzle without printing and see if it just goes straight down or if it starts to curl really close to the nozzle

a little curling is okay but if its just balling up by the nozzle it's probably clogged

shitty image but that's what it looks like when its a clog

[scenic otter]

Weird, let me send you what my head looks like.

[desert mango]

im gonna sleep, if u have more issues u can ping me tomorrow and i can try to help, or theres some other people with great advice

[scenic otter]

Ah sorry, I should sleep aswell! I'll be sure to ask you tomorrow if I need help.

G'nite

[desert mango]

night

[limber forge]

that looks normal

extrude some filament

and see if it curls up

[wide sinew]

Download this and make sure you bed is level

[scenic otter]

Yea, quick update. Cleaned it out, and everything seems near to level.

I keep getting this curls during turns though, and it causes the head to hit them when it round back, ruining the print. Any fix?

Bed heats 60C, extruder is 205

[tranquil wind]

Try 65 and preheat the bed. The temp drops pretty hard the further you get away

[mint rock]

Try when leveling your bed, raise it higher, also try powering the stop button for the extruder

[scenic otter]

Yea, I always pre heat. Will do 65 instead of 60 though.

[tranquil wind]

Good luck

[scenic otter]

Yea, I got a pretty decent level. Trying to fine tune it

the first couple layers go well, and then it kinda moves the printed part and ruins the rest of the print.

[scenic otter]

Still getting these weird hangs on certain corners. Beds at 65c, and extruder at 205.

Should I try raising/lowering these corners?

Seems to me the extruder is a little to far from the bed, and causes poor adhesion at the turns

[wind wren]

I think you should clean the bed but if it continues then yes

[scenic otter]

beds scratched up pretty bad from poor leveling from me, but shouldn't affect printing too much?

I can wipe it down with some alcohol

[wind wren]

Glass?

That looks like glass

Clean it with soap and warm water under your sink

Isopropyl alcohol will remove any coating from the factory that helps it stick, also it'll just smudge around any oils from your fingers or anything else so it's good to clean it with water

And soap

[scenic otter]

Think it is, Thanks I'll use soap and water instead

[wind wren]

Alright

[scenic otter]

I'll report back if this issues solves itself, it seems to get better with each minor tweak

[wind wren]

Alright

[scenic otter]

Ok, last issue

It seems there are circles in the top left corner of this print

Is the nozzle too close and just crushing the printed filament?

Heres a cleaner corner

Guessing to make the bed go more down on that side should fix it?

[limber forge]

that's not really a leveling thing

that has to do with your linear advance settings more likely

or acceleration

[scenic otter]

Ah I see. Any reason to fix it? Would it cause any issues?

Finished a bench, and gettin these weird rough lines. Guess I need to sand it?

[limber forge]

its not gonna cause any failures but may make your prints look a bit weird on the corners

https://www.youtube.com/watch?v=n3yK0lJ8TWM

that's a video on how to fix it, and the square on the left are the weird corners I was talking about

[scenic otter]

Oh I see. Would this have caused the weird benchy stuff I was getting?

[limber forge]

no thats something else
