Issue with printing with PLA (Stealthburner)

[Torwald]

Hello fellow Voron 2.4 users!
I have an issue with PLA prints. Fully tuned printer, everything is set properly (even with using ADXL).
The problem I have looks like this:


I have tried EVERYTHING, and NOTHING seems to work except getting rid of panels and printing without chamber. Event then it looks worse than prints I have done years ago on Ender 3.
Is Voron not capable of printing PLA in chamber? Seriously...

I thought that it would be a an ultimate printer and upgrade from Ender. Now it seems that Ender (in chamber too) work better...

My setup:
Voron 2.4 from Formbot
TAP
Stealthburner with Dragon HF

pls help - I have spent last week tinkering with Orca settings and failed...

Dragon hf has known issues with pla. If you want good pla prints you will need to use literally any hotend except a dragon hf.
The least expensive way to fix and test this is simply get a dragon sf heatbreak and swap it out.

PLA is not supposed to be printed in a chamber, you can get hear creep that way and potential clogs. This is not Voron Specific.

There is a setting called slow down for overhangs, increase your time there in the slicer.

I would say it is Voron specific, the enclosed X1C Bambu at my work prints PLA and TPU faster than I could ever get my V2.4 to the point of me adding exhaust fans and using different toolheads for my V2.4 to get better prints. I've spent the better part of the last week looking at the CPAP mods because I'm still unhappy with my Voron PLA prints with added 5015 fans, but the question is - another $200 worth of mods that might not work or another $1200 Bambu and get good at gluing and post processing smaller prints lol.

I bet you its more slicer related then hardware.

Just a little FYI, (since I do love my X1C) they have a large format printer coming out soon.

@StevenB
I got E3D V6 with the printer, might give it a go...

Ender 3 printed PLA in chamber just fine, for months - got it installed in IKEA Lack. Temps were the same as they are in Voron.
I have tried everything, nothing helped.


At this point I think it's either issue with cooling or DHF. I will try to find a bracket for E3D V6 to test.
If this also fails, I will have to get rid of all Silk PLA I got :/

I have had a similar problem on an un enclosed Core XY, turned out that it was insufficient part cooling. Changed my tool head from stealth burner to CPAP. Perfect prints every time now but it was a long road of trial and error,

Upgrade your stock fans with:

• Delta BFB0524HH 24V
• Orion OD4010-24HB

Giving a recommendation is great, but you should add the (why?) you recommend them.

I'd also like to know why. I'd also like to print with my chamber up, even if it meant blasting my exhaust fan
plus, they aren't tacho-enabled. not sure that would be an upgrade for my specific build.

More CFM is the answer. 5015 blowers have a wide range of CFM. My PLA prints were looking bad with a cheaper Winsin 5015 blower, that per spec was around 3 CFM (probably lower). I upgraded to a Berserker 5015 from West3D that's rated at 6 CFM and PLA prints are significantly better. (I'm using a Revo Voron hotend for reference)

I personally prefer Gdstime fans as they are some of the most powerful fans I have found. I have their 3010 on a dragon hf in one of my other printers and don't have a single issue with heat creep on PLA. I use their 4010 moves over 8cfm. Their 5015 moves over 5cfm @ 1.2 in H20 of static pressure. They are beasts. And I'm working a CPAP not CPAP mod using one of their big blowers.
