Tribotron - My first custom printer.

Hello everyone,

I am new here and just wanted to share with you my first custom made 3D printer codename Tribotron!


Here is a video of it in action:

It is available on thingiverse as well, alongside with source parts, materials list and (simple) build instructions if you are interested:

If you have any questions or criticism, I would love to hear.

Cheers!

I like the Z-axis, although it's a bit more complex than 'mine'.
Where did you find these extra long belts? I had to make some compromise regarding 'belt-wrap' and the front two ballscrews are not on the edge of the printbed.

Hey,

Yeah very similar indeed.
I initially thought of doing a triangle like yours but opted for this design so that it leaves space in within the frame for PSU and board. Something I ended up not doing in the end, so LOL
The only other real difference I can think is that you can change the ratio by only changing the motor driven leadscrew pulley, instead of all 3 leadscrew to something like a 60T like in your build, but yeah it is indeed a bit more complicated. I am not sure if for better or worse yet though.
It is a 1524mm belt. Here is a link to aliexpress product page.
I hope it helps!

That's a real sleek looking machine, love the stealth black look.

Try posting this on the corexy subforum, you might get more comments and feedback as it's a bit more active.

Thank you.

Yeah, I should have posted in the CoreXY subforum, but now, I wouldn't want to make double post and I don't see any way of moving the post :-/

Don't worry, no ones gonna get pissy about you posting to the coreXY forum. Simple mistake of chosing the wrong subforum, everyone does it.
Also, on second glance, is that an H-bot? The belts don't seem to cross anywhere. Either way, cool machine. What electronics is it running? I haven't heard of trigorrila which was listed in the thingiverse description.

I might as well do that then

Yes, it is an HBot indeed. Can easily be turned into a (crossing-belt) CoreXY though, which I have actually tried but didn't see any real benefit -at least in this machine- even though I do understand the theoretical advantages.
While when forcefully moved by hand there is a bit of a gantry twist, when actually printing there is none or negligible. In other words, it prints fine
Trigorilla board is made by Anycubic, probably the only Chinese printer company that I trust. It's 8-bit though but I might upgrade to a Duet in the future.
Other than that, electronics are 12v, MK3 heat bed and now using TMC2208 drivers.

Thanks again

Very nice. Good to see more people going the H-BOT way.

Hey, Thank you. I am glad you like it !
I also think that HBOT still has it's place
