3D45 heavy modding questions (self.3dprinting)

submitted 5 months ago by Dust0741 to c/3dprinting

6 comments fedilink hide all child comments

I'm wanting to heavily mod my 3D45. I basically want to use a raspberry pi to run it, but just repurpose the existing hardware. I am new to this area of 3d printing, and would love some suggestions to get started. I know of octoprint, but does it do all of the reading gcode?

If you're going to controll your board with another board, you might want to also look at Klipper. If you decide to go this route, the Voron documentation has pretty good setup instructions, but obviously you'll have to work out the specifics for your build. I personally really like what you can do with Klipper (macros, tuning, etc) and find it fairly straightforward.

If you go Klipper, the PI will parse the g-code, and apply things like pressure advance and resonance compensation, before sending instructions directly to your printer board.

Klipper + mainsail is truly great.

Never heard of this printer brand, but if it turns out that its mainboard isn't compatible with what you're trying to do then it might be an option to replace it with a cheap stepper driver board from AliExpress. You wouldn't need anything fancy if you're running Klipper on your RPi

This post has a little bit of age now, have you taken the Klipper pill yet?

[–] Dust0741 1 points 5 months ago (1 children)

Yup! Just got it installed on my pi. Still gotta wire it in. Any documentation to help? I haven't found out which controller I have yet.

I'm not familiar with your particular printer, but if it's popular at all you should be able to find the controller board online, from there you can probably find a pin out chart and maybe even a premade Klipper profile.

If you can't find a premade profile, the official Klipper website has a template profile you can copy/paste and fill in your board's pins/ settings. Once you get the hang of how things operate, your workflow will increase DRAMATICALLY, and the possibilities of what you can accomplish are limited to how much time you want to spend figuring out how to do it. I just eliminated the need to re-slice models between filaments that require completely different temp, retraction, PA etc settings, all it took was an afternoon and some coffee!
