Welcome to the SeeMeCNC Community

This is "Groot" from Guardians of the Galaxy printed really small - 70mm x 55mm. Cannot tell it's been 3D printed!

Welp, I know what I'm printing next!

Nice print!! I was thinking about printing it in some wood filled filament.

First time I've tried the .35mm nozzle w/ .05 layer height on the Max V2. I'm blown away as I can no longer see layer lines at all!!

What kind of print speed did you use??

45mm/sec

Extremely small part so layer to layer transition is easily too fast for appropriate cooling.

Wow. Those are some nice lines... or lack thereof. What nozzle size was that to get it that detailed without the lines present?

He mentioned it's a .35 nozzle. I just ordered one from SeeMeCNC to swap around with my stock .5 nozzle!

I've had a .35mm nozzle in my possession for a couple of weeks and this awesome print inspired me to give it a try.

After installing the nozzle and starting my print I noticed that the extruder was moving much faster than it was when I had the other stock 0.5mm nozzle. I am using kisslicer and printing from SD card. I just changed the settings in Kisslicer for nozzle diameter and extrusion width to 0.35mm. Did I miss something?

I was worried about the faster speed of the extruder, but it all looked amazing for a half hour of printing, so I left it to finish up unattended and when I came back to see the finished product it was more and more filament starved as it went along.

I was wondering if I should be tweaking anything like temperature or speed to make it work, or if I missed a setting for the nozzle or EEPROM setting or something.

Thanks!

Is your extruder making a clicking noise? Skipping? I ask because mine does if I try to run at any real speed. Head pressure is greater with the smaller nozzle I guess.

Try this (I use Simplify3D)

Use .42 for extrusion width
Slow down the head speed
bump up PLA temp to 215 or so.. That is what is working with Jet PLA
make sure your using the cooling fan on layer 2 and up

- Try cranking up your extrusion multiplier until its no longer starved in the print.

The smaller the nozzle size, the slower you have to print. Don't mess with the flow multiplier.

Thanks for this! I plugged in your numbers for extrusion width and upped my temperature. I have some improvement, but still having starvation issues but to a lesser extent.

I believe the issue is something wonky in Kisslicer, because I have the speed set to 10mm/sec and the extruder head is really moving a lot faster than that. I tried speeding it up and it seems that the speed setting did not have any effect.

With my 0.5mm nozzle, it works fine, and I can control the speed. I am not sure where it's going crazy, but it sure looks like the speed is too high and I can't slow it down.

I think this is the issue, but it looks like something is making the speed go too fast when I print this from kisslicer using an SDcard to print.
