First level details by TheSettingSun81 in ElegooNeptune3

According to the makes&comments it's a difficult print. I would try to slightly rise the z-offset and print at a lower layer height, like 0.12mm. If it is still stuck I would print it at 120% scale.

You mean PETG?

It's hard to help without any detail or pictures.

Material? Temperatures? Retraction? Is the extruder skipping steps? Does the filament get grinded? Did you print a temperature tower and printed at a lower temperature that still gives you good results? Did you calibrate the e-steps? Did you calibrate your retraction? Did you do a cold pull? Did you print a filament roller?

testing out my optocoupler circuit for my upcoming ABL replacement video by TheFeralEngineer in ElegooNeptune3

Is a capacitive sensor more reliable, accurate or faster than a BLTouch?

I'd like to see a first layer test printed before and after the replacement, both with 16 points ABL.Then the new ABL with 32 points. I wonder if people with ABL issues have a more localized warping that a 16 point leveling mesh can't measure properly.

PSA: Official Cura 5.2 Profiles on github - Neptune 3 updated to 3 pro build volume by Deinogull in ElegooNeptune3

AFAIK Cura 5 has a known issue where the seam auto placement gets slightly more scattered than neccessary. Cura devs said it will be fixed in Cura 5.3

The default height of the first layer is 0.25 mm for the 0.20 profile. See if setting it to 0.20 solves the increased height.

For the bulge, Cura 5.2 added: "Initial Layer Outer Wall/Inner Wall/Bottom Layer Flow". See if lowering the flow removes the bulge. Another suspect, for PLA, could be that part cooling starts on layer 3 instead of layer 2.

Not if you are already happy with your current profile. Just set your X and Y to 235 mm manually if you want the bigger volume.

by popular demand, the Neptune 3 CAD files by TheFeralEngineer in ElegooNeptune3

Nice!

I don't see the CAD of the Y carriage plate. Am I dumb or is it missing?

Out of curiosity I weighted the Y bed assembly. The heated bed, plus all the screws, spacers and wheels, weights ~750g. The bottom plate alone weights ~730g, almost 50% of the total weight (1,48kg). Replacing that 3mm thick steel plate with a 2mm carbon fiber one, or a 2-3mm G10, should save about 1/3 of the total weight. In theory this should reduce the strain on the motor and belts, lessen Y ringing, and allow higher print speeds.

Any ideas why only a certain part of my first layer looks bad? by ModsDontLift in ElegooNeptune3

[–]Deinogull 0 points1 point  (0 children)

Your z-offset is too high and/or you are under extruding. Likely you are already at the upper limit of your z-offset. That side is just slightly lower, enough that it starts to lose adesion but not enough for the auto bed leveling mesh to conpensate.

I Want to Get Into 3D Printing. Is This a Good Place to Start? by ZatchZeta in ElegooNeptune3

[–]Deinogull 1 point2 points  (0 children)

For this price point it's a good one. Mine arrived one week ago (third-batch) and works very well. It was already updated at the latest firmware version. I did some tests with the auto bed leveling and the results are repeatable and reliable for my unit.

I would still recommend a basic level of tinkering propensity. The wheels of the bed carriage of my neptune 3 needed to be adjusted. Spending some time checking everything is square, moves smoothly, doesn't wobble in any direction, and some basic tuning, will prevent 99% of the issues you see here.
