What are you making ⚒️ / 3D printing 🖨

[Sanguifier]

Didn’t have photos of my recent projects when I first stumbled across this thread, had to double back.

Hanging egg hide requested by my partner for a micro gecko terrarium.

Feeding trays for my dubia roach colonies.

Feeding ledge requested by my partner for a crested gecko terrarium.

Interesting failure I’ve had 3x on this print now. I thought it was a corruption in the .pm3n file after the second time, but I resliced a fresh .stl saved straight from CAD on the third and got the same weird stringers. Vat was cleaned between each print.

@XEMON

How do you doi it?
Do you send gcode manually to the machine or you have a print file that you run and go through the steps?

Sorry meant to respond
Yea I have it set up as a print file, I click print on it
(Octoprint, the pause setting doesn’t seem to work great or reliably on the printer board)

I’ll post code in a second, I can log in and steal the file

@XEMON

What are you seeing?
Maybe we can help making it more reliable for you

I’ve been printing a lot of ASA and managed to wear out three BuildTak like beds. I also have some problems with the squareness and rigidity of the gantry so I ordered additional screws to try out a few ideas but I’m still waiting for those to arrive. And I’m also waiting for a PEI bed.

Regarding other problems, I have a high flow hotend sitting in a box because I couldn’t never get it to work right. And I have an SKR Mini E3 V3 but I have to recompile Marlin and tweak a few things so that it prints reliably.

I’m wondering if I should get a CR Touch for it but I’m hesitant as my experience has been a bit of a roller coaster.

[Hamspiced]

I recommend the bltouch. Cr touch is essentially the same but my experience is with the bl touch. It makes leveling absolutely a second thought

I borrowed some elements from something else a while ago, no idea where I got it from, so don’t give me credit or blame lol

The pause feature is fairly broken using sd cards, least for me

In octoprint it pauses in the UI and I can hit resume

Why do you heat the bed for a filament change?

[Eriequiet]

Usually if I’m doing a filament change, I’m about to print something… and my bed is the slowest thing to heat up… so get the bed already warmed up… it also takes a while to cool off

I also over heat it, always 230… just because then I can use the same script for petg or pla

It’s usually only heated that high for a minute or 2, so it’s been fine

[CoreySpondant]

@Eriequiet

I also over heat it, always 230… just because then I can use the same script for petg or pla

Also makes the auto-home at the beginning of the print take less from the heat “battery” you have built up in the hotend. In my experience it’ll drop 10°c-20°c from when it starts to home to when it decides to start heating the hotend again.

[Eriequiet]

Bingo……
If I was motivated I could flip it around so it homes before it cooldowns

But I don’t care enough… the 80% first try was good enough and I don’t have enough motivation to go back in lol

[r00t]

Hey @amal, how do you like your bambu? I was eyeing it for a while and still cannot make my mind between it and prusa mk4. I really would like to support prusa because of the opensource nature of things.

[amal]

for me, i like it. yes it is connected to the cloud and talks to china for basically everything and they still have not enabled “local LAN only” operation after a year+ of promising it… but yeah with the AMS it does exactly what I want… i don’t touch it for days or weeks, then when I need something I turn it on and hit print and it prints perfectly and I turn it off. great.

[Hamspiced]

In all my reading that would be my choice if I had the expendable income for it. But I do like to tinker so I don’t mind my ender

[amal]

@Hamspiced

But I do like to tinker

this is one of the down sides to businessing… the transition from garage tinkerer to desk jockey is difficult to resist.

[Hamspiced]

I feel that. I enjoy tinkering too much to run a business. I don’t know how you or say Linus even does it.

[r00t]

Thanks for the feedback Amal. Yeah, not a big fan of sending stls to china for a “backup/cloud print”. Not that I am doing some super secret RnD, but again, you may never know. I like to play with my toys, so I think the prusa is very versatile platform with upgradability in mind. Also it’s EU based business. Unfortunately I do not have a big basement where I can put this printer, and I do not want to place it in my living room. Not a huge fan of making my fam breathing the melting plastic fumes either.

@Hamspiced

Time to print a fume extractor carbon filter

What’s the line?

Printer’s printers print prints for printer’s printers more than printers print prints for printed projects.

[enginerd]

I might get a Prusa at some point. Or build a Voron depending on how much free time I have.

While I would probably enjoy a Bambu and end up using almost every day, the added privacy is nice to have and I’m ok with a slower machine as long as it’s reliable and I don’t have to worry about it.
