Creality Ender 3, setup, mods/improvements and how-tos [serious]

Use 70 and try again. BTW where is this printer located? somewhere cold? Might wanna heat up the bed for 10 minutes before you start printing. It could also be due to poor bed print adhesion. Do you use hair spray?

Reduce retractions. Your effective retractions are way stronger now. start with 0.1 and increment in steps of 0.1

Yep. I’ve already dialed them to 1.2 and seems to be perfect.

Sorry, I was not very clear. The one on the left is with the enclosure and does not have any warping. The one on the right was printed before I installed the enclosure. I am very happy with the enclosure as I have lost a lot of prints due to warping. Thanks for all of your help with this issue.

1.2 is still a bit much for direct drive. At least for BGM extruder. For yours maybe 1.2 is appropriate, I don’t know. my retractions are less than 0.5mm with BGM.

Did you print this in vase mode?

I’m just using all stock parts except for the mounting plate.

Yep. I used vase mode for this one.

Always happy to help. You had said before and after so I was looking from left to right :smiley:

hmm. A pic would help to guess where the holes are coming from. I though the retraction sucked up a lot of material and created a separation between the filament and the molten pool. It might also be due to the retraction speed, since you have gone direct, reducing the speed is recommended. Try 30mm/sec retraction speed to be gentle on it and not create an air gap.

But if the gap is coming from something else then obviously changing retraction settings won’t help. Pic would help.

My prints are coming out perfect. I’m not changing a thing mish. :wink:

Ahhh. I misread it totally. I thought you are having holes in print now. Silly me.

The vase print looks great BTW. Especially that it’s with PETG.

Gotcha.

Yeah. This was before direct drive.

This is after. Comes out perfect no hole, strings or anything.

Only change I made was retraction distance. :slight_smile:

That would have been retraction and retraction prime settings need tweaking. With less compression of the filament due to direct drive these settings have less of a effect.

The down side to direct drive is the extra weight on the z axis can cause salmon skining at fast speeds.

You can also get dule z axis screws for the Ender 3 to counteract the z axis droop (single or dule z steeper options.

I got a single steeper version coming from Banggood to run on Bowden’s tube set up hoping for less flex from the z axis when printing things on the right of the bed.

will @DerelictRobot come over for sleep overs with their own room?

You have made so much progress into 3D printing than most of us here and that too in such a short amount of time. You gotta print TPU and alloy 910 next, now that you have a solid setup.

70deg bed is too low for a glass bed. The sensors sits below the bed, if you add a glass layer surface temp is much lower than measured. I’m running mine at 100deg without problems and additional helpers (glue etc), 90deg should be sufficient though.
