AI Help

To improve your print quality, you could consider the following adjustments:

1. Increase Z Offset: You might want to try adjusting the Z offset slightly, as a higher value can improve first layer adhesion.

2. Lower Print Speed: Printing at 250 mm/s is very fast for most FDM printers. Try decreasing it to a more standard speed of around 50-60 mm/s for better quality.

3. Adjust Retraction Settings: You could experiment with different retraction distances and speeds to reduce stringing in your prints.

4. Fine-tune Temperature Settings: While your temperature settings seem standard for PLA, some PLA filaments may benefit from slight adjustments in temperature. You could try lowering the temperature by 5-10 degrees to see if it affects quality.

5. Check Cooling: Ensure that the print cooling fan is working properly and consider experimenting with different fan speeds for different parts of the print.

6. Infill Density: Increasing the infill density slightly...

That looks fine, nothing to complain about, why are you creating a help post? Is there something specific you need help with?

Overhangs are hard, it's expected they fail like that at some point

[tropic ginkgo]

Yes, needed help with figuring out if this is how it should be.
I am completely new to FDM printers, I only have experience with resin printers but they arent exactly the same.

Yea the overhangs had me worried

[robust leaf]

There are tons of settings that can help overhangs. You can slow down for overhangs, for example. Otherwise if you want better overhang performance, you need more cooling

[tropic ginkgo]

Oh well, I doubt ill be printing much overhangs anyway

[robust leaf]

Since you already said your cooling is at 100%, that leaves you a couple options, either print yourself a better fan duct, or buy better fans

[tropic ginkgo]

What about the text on the surface of the print, is there any way to get it be sharper/less unreadable?

[robust leaf]

Which text specifically?

[tropic ginkgo]

3rd picture, diameter section on bottom left, the smallest diameter text, to the right of 6mm diameter. I cant make out the number of the diameter

I think it supposed to be 3 but honestly, just looks like a blob

[robust leaf]

Is your filament dry? What filament did you use? The stuff that came with the printer?

What speed did you print at?

[tropic ginkgo]

Yes, Elegoo pla rapid+, no, set at 250mm/s

[robust leaf]

250mm/s is likely your culprit there. Slow down for the top layers and it'll print much nicer. There are settings in cura for top surface speeds.

250mm/s is very quick for most printers, you'll get much better results slower.

Also, for what it's worth, the rapid filaments are a bit of a scam. You can save money and just buy the normal ones

[tropic ginkgo]

Heres a lil sharper pic of what I meant regarding blobby

Thx, ill try adjusting the print speeds a lil

[robust leaf]

It actually looks like you're underextruding a bit

So either your extruder can't keep up, or your flow isn't set correctly.

[tropic ginkgo]

Print flow is set at 94%

[robust leaf]

I'd try printing a flow test and see how that looks

Yeah you see how you can sorta see THROUGH the top layer?

Like it looks like a cross hatch?

you shouldn't be able to do that

It should be solid

[tropic ginkgo]

hmm, ill try increasing a flow precentage a lil

[robust leaf]

If you don't know, cura has lots of plugins that have calibration prints, I'd go look in the "marketplace" section if you haven't already

[tropic ginkgo]

yea ill take alook

[robust leaf]

Sounds good, yeah, a few things to check, flow, speed, and I can't stress the dryness of your filament. It's really important in FDM, and new filament straight out of the package is almost never dry. Especially for things like overhangs! But yeah, report back, tag me 🙂

Also, another thing if you're new to FDM you may not know. The print temps on the filament packages are suggestions. PLA prints well up to 270 C, especially at higher speeds. At high speeds like that, 220 is very low. That could explain your underextrusion as well.

You should print a temp calibration tower to find the "best" temp.

For FDM, I usually tune Temp -> Flow -> Pressure Advance (this may be tricky in cura as it doesn't... natively support klipper) -> Retraction

Also, for FDM, higher temps mean better layer adhesion, but worse overhangs/bridging. So you balance the two.
