3D PRINTING

The H2S arrived today. What a freaking machine. One of the most incredible pieces of machinery I have ever purchased.

Even the packaging was beautiful. Plugged it in, calibrated it, and it's printing the most beautiful prints I've ever seen within 2 hours of purchase.

If you're on the fence about what manufacturer to go with, just go Bambu. There's simply no substitute in this marketplace.
 
Can someone with a 3d printer make me a cup holder? I'm looking for something like the picture attached but with a single cup holder. I'm willing to pay of course.

DM me, sounds like a fun project.
My son is working through his engineering tech degree and needs projects like this to keep him excited.

Gonna need dimensions of the space it fits in.
 
Well the honeymoon with the H2S is over. I'm packing it up and sending it right back to Bambu. What a POS.

Small simple prints work just fine. Anything above 3 inches fails every single time. Thing just self destructs. Every model I try, every filament I try, every setting, every tweak. Nothing. It simply doesn't work. It's almost 100% a hardware problem with something wrong with the printer itself. Nothing else makes sense.

If I wanted to fiddle around and tweak things, I'd have bought a Qidi Max Q2. Fuck this thing, seriously.

Honestly makes no sense at all. It's the same failure, in the same location, at the same height every single time. I've messed with everything I possibly can and it just won't work beyond 3 inches or so. Absolutely ridiculous for a 1700 machine that is supposed to work "out of the box".

But I will say that anything simple and less than an inch tall prints beautifully, but if I wanted just that, I'd have gone with the A1 or something cheap.

what kind of failure? Sounds like something is blocking the Z lead screw travel

Understood, I just thought the total swing from a 5 star review to a 1 star review was humorous.

I posted the time-lapse video on another post. It's hard to catch but the whole thing just stops functioning. Honestly that lead screw thing is a good bet. It does appear that the printer head crashes in to the prints.

I'm not sure what would possibly be blocking the z screw though. Especially since it has no problem moving up and down when not printing anything.

what kind of trouble shooting have you done?
Did you try just manually moving the bed up and down past that point and seeing it it sticks?
 
I know nothing about these machines, but on big CNC machines, there's generally 3 limits:
Soft limit, programmed and changeable in the software
Absolute limit, coded in by the manufacturer
Hard limit/mechnical limit, physical travel limitation due to interference.

Mostly filament based at this point. Dried everything, changed all the settings I know of for it to be related, changed filament types, profiles.

Cleaned the bed over and over again. Handled it with gloves. Tried multiple different prints.

I haven't tried manually moving the bed yet. I'll try that tomorrow. I'm not sure what would be limiting the travel though. When it comes from the factory, the bed is all the way down on the bottom. If it rose up to calibrate, it has to be able to move as it should. I actually calibrated twice because I moved printer locations.
 
So I'm finally able to sit down and muck about in Bambu Studio. I haven't had a ton of time to do this and I've been using the Handy app.

It seems like all the default profiles for filament are built for speed. Like, absurd speed. I'm thinking perhaps that's part of the issue. Overture filament is apparently okay at Bambu speeds, but not ideal. I've slowed the print speeds down to what I'm familiar dealing with Overture on. A little slow but whatever. I ordered a boat load of Bambu filament which I think is designed for their faster speeds.

I also suspect that the failures are happening because of both the print speed and because the machine has some vicious shake to it. Evidently it's built to move and the machine compensates for it, but I think coupled with the Overture not being super great at fast speeds, it's causing the problem. I've got some stabilizing feet printing now.

I also ordered a Biqu Glacial plate for it. Seems like the Bambu PEI is picky and many don't seem to think it's very good.

FWIW, Bambu customer service was super quick about responding to me. They've sent some files over they want printed to see the results. I'll try them tomorrow.

I was salty before, but frankly I haven't done enough true troubleshooting to be about that. Nothing I've printed has come from the slicer and the Handy app is only good for really quick hands off stuff.

Edit*

God I feel dumb. I strongly believe the failure was 100% related to default filament profiles trying to print at the speed of light. I'm pretty certain I'll have finished dessicant containers tomorrow with no issues at slower speeds.

Throw away the Handy app. It's useless except for being extremely lazy.
