I just picked up a Max 3, and yeah, after a quick calibration, it’s been rock solid. I picked mine up for about $650.

Oh, I am right there with you. I don’t want to write tests because they’re tedious, so I backfill with the AI at least starting me off on it. It’s a lot easier for me to fix something (even if it turns into a complete rewrite) than to start from a blank file.

I’ve used them for unit tests and it still makes some really weird decisions sometimes. Like building an array of json objects that it feeds into one super long test with a bunch of switch conditions. When I saw that one I scratched my head for a little bit.

Hoo boy I had it going way too fast. I had it moving at 150mm/s. I very strongly suspect this is about 90% of my problem. Layer quality already seems vastly improved a few layers in at 50mm/s. I very much appreciate the insight!

I haven’t run PLA on this printer. This is actually my second one, I modded my first one to the point of unusability. Maybe starting back with PLA is a good idea.

I’ll try dropping temps and see what I get. Thank you!

I haven’t had issues with curling but the enclosure is pretty new. The room is pretty variable with temps. The windows are old and maybe a little leaky.

Word. I’ll give that a go, thank you.

They’re sequential, so the values above and below yours are valid SSNs of people born in the same hospital around the same time.

This would make it trivially easy to get access to records you shouldn’t

There were three distinct arcs to it, so that might contribute to it feeling short.

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.

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.

Haha! I had a Mini T as my first one. It was a fun little car!

Check out the Tarmo project. I’ve been wanting to put one together for a while.

I realize I’m reviving a super old post here, but I actually did end up figuring out what it was. I posted a little writeup in here if you’re at all curious. You were actually kinda close.

Because I hate when people ask questions and never go back to update their original post when they solve the issue, I’m gonna post an update here and now.

The fix was actually surprising but simple. I ended up moving the second Z axis lead screw carriage mount a bit further towards the motor. That is, the piece that supports the build plate, where it connects to the leadscrew.

Further diagnostics ended up showing me that it was binding, and one of the problems I had later on was that it was binding but only when going up. So I ended up having prints that got progressively more and more stretched out along the z axis.

Moving it to be further in line and loosening a few mount screws to allow the nut to come back to vertical got me to where I needed to be. Hope this helps!

The print before this one, the blobbing/shreds were tall enough that one grabbed the BLTouch probe and bent it a little. I was pretty mad about that tbh.

I’ll double check my connectors. That’s a solid shout actually.

I think I’ll give that a swing. Thanks for your input!

I think you might be onto something but the other direction. I think it’s not moving quite enough per layer.

I haven’t run a temp tower. I’m not fully convinced that it won’t damage itself so I’ve been trying to think through it before trying another print.
