Stringing no matter what retraction settings? | 3D Printing | Page 1

left stream Jul 15, 2023, 8:35 PM

Hello, I've used http://retractioncalibration.com/ on it's default settings and I'm getting stringing on all of them. I'm running a Anycubic Vyper and using Flashforge Burnt Titanium filament in a dryer kept at 45C for humidity management. I've calibrated my e steps, K value, the bed is level, and I'm printing at 190 which was determined by using a temp tower. From my experience, adding z-hop only makes it worse. Any advice on how I can get rid of this stringing? I'm using Zombie Vyper 2.8 firmware for linear acceleration.

AI Help

It sounds like you have already taken many steps to troubleshoot your stringing issue. Here are a few additional suggestions you can try:

Check retraction distance and speed: Make sure that your retraction settings are appropriate for your printer and filament combination. Experiment with different retraction distances and speeds to find the optimal values that minimize stringing.
Adjust printing temperature: While you mentioned that you determined 190°C as the best temperature using a temperature tower, it's worth experimenting with slightly higher or lower temperatures to see if it helps reduce stringing. Some filaments may require a higher or lower temperature than the suggested range.
Filament drying: Although you mentioned that you are storing your filament in a dryer at 45°C for humidity management, it's worth confirming that the filament itself is not absorbing any moisture. Try drying the filament in an oven or using a dedicated filament dryer to eliminate any mo...

I've calculated my flow rate as well, and while this doesn't account for that, my stringing tests in Cura still have the same issue even though flow rate is correct

How old is your nozzle

A week or so, I just replaced the hotend

#

Of course that doesn't mean it's in perfect shape, I was struggling with leveling before I realized that it wasn't using the stored mesh, it's possible it touched down at some point when I was working on that

I have checked for clogs and all by doing a cold pull and using the 0.4mm needle

left stream Hello, I've used http://retractioncalibration.com/ on it's default settings and ...

This model just doesn't tell me much, looks like there more going on then stringing, id suggest printing a normal retraction tower. Those are alot more readable imo

#

From the looks of this it just seems like you need to crank your retraction speed and length way up. The vyper has bowden right?

left stream Jul 15, 2023, 10:56 PM

#

I can do that, though whenever I do, it tends to look alright, it's only with thin tips like say spikes or small bits where the issues come up. Let me finish this print and I can try a normal retraction tower

#

Yeah it's bowden

sage wyvern Jul 15, 2023, 10:56 PM

#

What are your retraction settings

left stream Jul 15, 2023, 10:56 PM

#

Currently it's 6.5mm at 70mm/s, the high speed was just due to testing

#

I've tried multiple speeds to no avail, not really sure what the cap on it should be to not cause issues with the extruder/clogging

#

No Z-hop, no extra prime amount

sage wyvern Jul 15, 2023, 10:57 PM

#

Is your bowden tube sitting in the hottend correctly

#

Not cut off at an angle whatsoever

left stream Jul 15, 2023, 10:58 PM

Nope, it's connected via capricorn tubing to it's mount

Oh I misread, no, no angle

i mean i know that it comes with auto leveling should i look in to that at all? or just do the auto?

left stream Jul 20, 2023, 8:53 PM

#

Ok so that's actually a thing I found out after a LOOOONG time troubleshooting. I'm using Octoprint for printing and cura for slicing. I found out that if you level your bed and save it with M500, that doesn't mean it'll use it. I had to add M420 S1 to my cura settings before every print for it actually use the bed level mesh, that fixed any first layer issues I was having

#

M420 S1 selects the first bed level mesh for use in the print, without it, it was ignoring the auto level settings

#

That's actually how I damaged my nozzle, by it running into the bed because I was fighting with Z-offset when I didn't need to

spiral pasture Jul 20, 2023, 8:55 PM

#

is it a plugin?

left stream Jul 20, 2023, 8:55 PM

Nope, if you're using Cura, you go into your printer profile, and in the bottom left you'll see the commands that are sent before a print begins, I just added it there

Oh, one thing, becuase I don't really know how the vyper handles it normally

spiral pasture Jul 20, 2023, 9:04 PM

#

dam nvm

left stream Jul 20, 2023, 9:04 PM

#

I don't think it saves the bed mesh to the EEProm normally, at least from what I've seen from watching the console

#

So techincally it kinda expects you to level every time it's booted up

#

But you can save it

#

One sec lemme make sure I get the right codes for you

spiral pasture Jul 20, 2023, 9:06 PM

#

#

do you think the nozzel is broken here as will?

left stream Jul 20, 2023, 9:07 PM

#

Not sure, Z-hop on can cause that from what I've seen

spiral pasture Jul 20, 2023, 9:07 PM

#

less turn it off and see i mean it is way cleaner the before.

left stream Jul 20, 2023, 9:07 PM

#

Ok so, to save the bed mesh, you can insert G29 to run an auto-level, then under that line you can run M500 to save it

#

If you're about to start a new print, you might wanna do that now, so it's saved for the future

#

Just this once add this to the start Gcode:

G29
M500

#

Then after this print you can remove it

#

Add it before the M420 line

spiral pasture Jul 20, 2023, 9:10 PM

#

so something like this?

left stream Jul 20, 2023, 9:10 PM

#

Move them up before M420

#

So it gets the new bed mesh

spiral pasture Jul 20, 2023, 9:11 PM

#

i see

left stream Jul 20, 2023, 9:11 PM

#

I'd move them to the top for now, I think you also want M420 before a couple of those. I'm not sure but better to be safe I suppose

#

I don't know the exact point it needs to load the mesh by

#

So I do it earlier

spiral pasture Jul 20, 2023, 9:12 PM

left stream Jul 20, 2023, 9:14 PM

#

With AutoTower Generator it will use your normal print settings except the one it's testing. So if you're testing retraction distance, it'll keep your configured retraction speed, printing temp, printing speed, etc. Only the retraction distance will change during the print

spiral pasture Jul 20, 2023, 9:14 PM

#

ah i see

left stream Jul 20, 2023, 9:14 PM

#

I normally do temp first, set that in the material profile and print profile, then retraction distance and set that, then retraction speed

spiral pasture Jul 20, 2023, 9:15 PM

#

should i change any of this before printing?

#

do you have a sweet spot you found?

left stream Jul 20, 2023, 9:15 PM

#

Which if you weren't aware of, material profiles are really nice if you don't use the same filament all the time

#

It all really depends on the filament, you should calibrate each filament you get and save the settings in cura

spiral pasture Jul 20, 2023, 9:16 PM

#

i am only planing to use PLA for now

left stream Jul 20, 2023, 9:16 PM

#

what should i put this at?

left stream Jul 20, 2023, 9:17 PM

#

You've got to calibrate it first to find out

spiral pasture Jul 20, 2023, 9:18 PM

#

when i am doing the temp tower what am i trying to figur out?

#

also does it do it auto or should i change the temp each time?

left stream Jul 20, 2023, 9:19 PM

#

When you select the filament in the Prepare tab, it'll automatically change the settings to match it's settings. It'll prompt you to keep or discard changes when you switch

#

As for the temp tower and calibration, I actually have a good site for this, one sec

#

https://teachingtechyt.github.io/calibration.html#intro

This page goes through all the ways to calibrate your printer and all. With videos and everything to guide you. You don't have to do everything, but it's a really good resource if you need to troubleshoot something

spiral pasture Jul 20, 2023, 9:21 PM

#

i see

left stream Jul 20, 2023, 9:23 PM

#

For the temp tower, I look for a smooth print, where there isn't any loose strings on the bridge or anything that looks wrong (like stringing, melting, etc). Usually you'll see a range that looks alright, at that point you just pick the one that looks the best for you

#

For retraction, I look for the lowest amount that doesn't string. I've found that the Vyper doesn't usually need the 6-8mm retraction that other bowden extruders do, I'm usually closer to 3-5mm

#

And for speed it's the same thing, I set it to whatever I found looked good in the distance test, then look for the highest speed that still looks good on the speed test

spiral pasture Jul 20, 2023, 9:24 PM

#

this what i got today

#

from 220 to 190

#

this was before changing filament but it is from the same brand.

left stream Jul 20, 2023, 9:27 PM

#

The bottom on the right picture looks like it's too high, it's all melty and that's why it's stringing like crazy. I'd turn off Z-hop and try again. I'd also recommend going though the calibration steps on that site. Once I went though everything I could, I have much better prints. I'd wager with that result, once you get stringing under control is probably going to print somewhere around 190-200, but stringing is making it hard to read

#

Have your filaments been left out for a good while? They can absorb moisture and that can cause a lot of printing problems because it makes it brittle

#

I personally bought a filament dryer for live use, but you can also use a few other things like a dehydrator or an oven (if it can go low enough, mine can't) to dry them out

#

I can't say that's whats causing the issues or anything, but dry filament is happy filament
