So, I changed the nozzle to 0.35mm...

[Agisis]

...and updated the quality setting for one of my configurations to use 0.35mm nozzle size. When I print, it prints in lines (meaning spaces between each row on the bottom layer) as though it has a 0.5mm nozzle even though the nozzle is 0.35mm and the settings are correct. I have printed in 0.35mm before and this did not happen. Anyone have any ideas? (Nozzle Diameter is set to 0.35). This is very very confounding and makes it a bit of a struggle obviously to produce fine quality prints

Which slicer? Are you slicing in a host software or a standalone slicer? Are all the other settings identical with the previous configuration?

[Agisis]

using standard slicer. no changes to anything at all, just nozzle. I usually make a duplicate of whatever configuration I have set up and name it with the nozzle size (I.e. MH-Black-PLA-0.35mm-Fine for example). very weird stuff and I don't like weird especially when I've done lots of nice prints with 0.35mm in the past. I also noticed my eeprom settings for the horizontal radius and rod lengths were reset somehow back to the original values so I had to recalibrate the whole thing. It still gave me lines with spaces between them as though it was thinking it was 0.5mm instead of 0.35mm. I upgraded MC just in case, no luck. I also thought maybe it was because I scaled my model and perhaps it scaled it with 0.5mm in mind and when I switched to 0.35mm it didn't reslice or something, but starting over didn't help either.

I wonder..when you change nozzle diameter, shouldn't the extrusion rate change as well automatically?

[IMBoring25]

It should.

If you lost your EEPROM, I'd look into recalibrating your extruder steps/mm.

I remember seeing a setting for first layer width.

And when i applied that my first layers were much wider extruded. But on the thread i was following it was mentionned that this was not really good for bed adhesion so i abandonned that approach and cannot remember much.

I think it was something called first layer extrusion multiplier.

This was in matter control/slice.

[teoman]

Is this for all layers?

[Agisis]

seems to be happening for all layers.
Crap, the tornado sirens are going off. got to go! (In Dallas TX)

Well hopefully the tornado didn't get you.

One thing people forget (or simply don't know) is that has your nozzle diameter decreases, so must your print speed. When I run a .35 nozzle, I keep the print speed round 30mm/sec or less. You also need to make sure you've told your slicer what the new nozzle diameter is.

No tornado got me. heh. I can try lowering the print speed and I am curious to try it with a higher extrusion rate. The slicer configuration setting I am using has it set to 0.35mm for nozzle size and it shows up in the display. I will try again later tonight and post a pic of it if it is still happening.

[Agisis]

It's starting to look like it might have been the way the slicer was chopping up the model. I printed some another set of objects tonight and it did not exhibit the same issues. very weird!!!
