Designing a new printer (midwest.social)

I'm looking at making a new printer. I'm thinking a core XY similar to a Voron, but I would be making it from scratch. I'm looking for something I can make reliable and accurate. I want to print PLA, ABS, TPU and more. I have a bunch of parts now that I would stick to.

235mm heated bed Revo hot end Nema 17 motors. BTT E3 mini, although I could use my SKR3 instead.

The easiest would be a bed slinger, but I am open to a Trident style. I like unique and challenging things.

What new features should I include? What should I avoid?

I built myself a 400x400x500 CoreXY machine from scratch.

Honestly, my prints are dogshit unless I go slow, and then sometimes they're dogshit anyway. I have found the entire exercise as one of futility and massive frustration... but I low key love fucking with it. I can't help myself, I keep building upgrades and improvements for it. I keep sinking time and energy I don't have (and cash that I do) into this fucking heap of shit and I can't help but love it to pieces. It's dumb as fuck and it's pretty fun to work on.

Honestly the vibes are about the same for a project car. Don't daily it or you will hate yourself, but if you put it together and tune it right, you'll have a blast.

Exactly. I made a delta printer about 10 years ago from scratch. Every part has been updated and updated again. Its an adventure.

Do you have any pictures or info on your printer? What would you change?

Have you looked at Klipper to tune out the high speed Issues?

[–] franzfurdinand 3 points 3 months ago

I'm not ready to make the jump to Klipper just yet. I want to iron out hardware issues first.

I have a couple important takeaways. First, build the damn thing to be actually rigid out of the box. I thought I could keep it cheap with only 2020 extrusions, but I'm honestly paying a helluva lot more to add some stiffness to it.

Second, plan for your wiring at any given point to double. I got really tidy with my wiring at first and now it's an absolute nightmare. I gave up and half of it dangles off the back on the floor. It works but I really could have done a lot better with some better planning. It is truly a shameful sight.

I did add an extra pair of motors to the Z axis, bringing me to a grand total of four. I'm waiting on some stepper drivers to get it going again.

I don't have any pictures on hand, but could take some later.
