#What settings should I look for?

I just got myself a Bondtech CHT 0.4 abrasive nozzle and I am getting gaps in between my layers / walls at the end of the extrusion line. What settings in Cura should I look at to seal those gaps and possibly lessen that internal facing ooze?

To address gaps between layers and walls, a few settings in Cura can be adjusted:

  1. First, ensure that your nozzle diameter is correctly set to 0.4mm in Cura. This should match your nozzle size.

  2. Increase the number of top/bottom layers and perimeter (wall) count to create more solid layers. This can help fill in any gaps and provide better structural integrity to your print.

  3. Adjusting the extrusion multiplier can also help. Try increasing it slightly, such as by 5-10%, to increase the amount of filament being extruded. This can help close any gaps between layers.

  4. You may also need to fine-tune your printing temperature. Higher temperatures can improve layer adhesion, while lower temperatures can reduce any potential oozing. Experiment with small temperature adjustments (e.g., 5-degree increments) until you find the right balance.

Additionally, make sure your filament is well-dried and stored correctly to avoid moisture-related issues. If the problem persists, you migh...

but linear advance is mostly set on the printer

So retraction didn't really do much unless it is too much even at 0.5mm. I went up to 1mm with no noticeable difference that I could see.

I am doing a test print now for priming. I tried a few different "retract at" checkbox settings. What sort of value should I look for with priming? based on the coasting setting (which is disabled) I am starting with 0.064mm^3.

I unfortunately can't do linear / pressure advance as my printer is running Chitu. I do have plans to upgrade the firmware in the future, but I am doing strictly motion / hardware upgrades till i am satisfied. Even though the firmware is crap I get some nice quality prints so far.

Yeah can't really say for your printer as everyone is different, i usually just
-Esteps calibration
-temp tuning
-retraction tuning ( speed then amount but its just my style)
then extra prime if there is holes
if it still doesnt work I'll do flow rate increase cause i rather have blobbing then holes

What fixed mine was the esteps calibration tho cause it waaay off on the ender 3 i had

Prior to this I replaced and calibrated my extruder as the idler shaft was worn away and the bearing felt crunchy. I did have to change my flow rate a little, but I increased it. While I never really got "bumps", I always liked to get a 0.42 extrusion width for that extra wall overlap strength.

Everything else more or less stayed the same with the exception of a PID tune after the nozzle install. It's just after said install is when the problem appeared.

#

extra prime seems to have shrunk the hole, so I'm going to up it and print another test.

also try printing alittle hotter

3d printing is worse than fixing a car
