Yeah. If you are good for pla, it's not likely the cause.

Thanks! I hadn't considered the slicers. I don't have a driving need multi-matrtial -- mostly considering that if I'm going to invest in building a printer, I'd want it to be capable in all ways.

Thanks. My main speed issue, I think, is the size of the bed. My base unit was an ender 3 max with a 300x300 bed. On a fast print that bed swings with enough energy to actual move the printer.

I say likely is that I haven't attempted to solve the issue yet -- I don't need the speed, I simply enjoy tinkering and this is one are I havent.

Having said that, from the original post, while I want to build one from scratch, I'll probably continue tinkering on my custom printer as well.

I've played with up to a 1.0mm nozzle -- haven't had results yet.

I had similar messy results at one point -- it tuned out to be a bad zOffset. Having said that, my part also as a messy top layer -- not sure if yours has that or not with the little nub there.

Im also all Linux and like many of the other commenters, I mainly use openscad as my primary and freecad. There is a lot of free training video and walkthroughs for both.

Awesome. Thank you for the reply. Sounds like it is time to start printing and collecting parts.
