So, I bought myself a rpi4 and installed Klipper. Very cool firmware quite enjoying it. Still tuning but i’ve got my speed up 3x from my Marlin based firmware. I think I’ll continue looking at the options here recommended and build one – mostly because I want to – not because I am solving a problem. Thanks for putting me onto Klipper.
So… I still have some tuning.
I learned that you need to adjust retraction and z offset again after implementing pressure advance… But I’m close now. 
Oh boy… Yes scripting comes easy to me. It’s why my default is openscad for making 3d models. :). I’m printing the pressure advance cube model now.
I agree, not just the perimeter but also when it’s going back and forth to fill in the centre area. I’m not sure how to address it – maybe the pressure advance settings LazaroFilm suggested. I’ve also tried printing at a series of different temperatures…
I’ll check that out. I installed klipper yesterday for S&G – actually quite liking the flexibility it gives me. I see the guide.
in those two cases, they are PETG and bed temp was 80. The curved edges were caused by me removing the print from the hot bed… not lifting off during the print.
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.
I run linux on my gaming rig. I’ve had the best luck with performance of graphics cards with manjaro and pop. I am not a huge fan of gnome and prefer kde (FWIW, gnome works fine, I just prefer the feel of kde).
With the above in mind, I really like the newness of the packages on rolling distros like Manjaro/arch. Yes, it can break things but Manjaro tends to be a bit behind Arch on releases – maybe this helps? The AUR is awesome. I also like several of the gui tools Manjaro has implemented to make graphics driver installs simpler.
Pop worked really well and was simplier for gaming – especially on devices with hybrid graphics.
That being said, I haven’t used Mint since the forums were hacked. I haven’t used Ubuntu since they started devaluing their users (integrated Amazon?, forcing snap?). Fedora is nice but I found pop/manjaro better for gaming due to graphics support.
My advice to you – what you are asking is one of the main benefits of linux – personal choice.
So… get out your USB stick and try them. Use the forums to help you with the nuances and make each work for your needs. Then see what you prefer. Then donate to that project and its base project.
It’s awesome to have choice.
