#- (hash) printer with super simple gantry

@o_lampe you could go old school and print with rafts.

That came to my mind, too. But it takes extra time to print the raft and I'm afraid that even with 4 extruders in copy mode it melts down the otherwise significant time-advantage.

Arkanoid style animation would be fun, three balls drawing bricks, that a third one destroys (-:

I'd be happy to play TicTacToe, but if you write a meta-code macro for Arcanoid, I'll try it for sure

@o_lampe sure it won't be fast, but proving the concept is the first step to get it optimized. I get your hesitation though, and the world needs more sand tables (-:

@oliof
One Arcade classic game would be suitable for a sand table : Tron
Or Snake for single player

Quad ball sand table is by far the coolest option IMHO.

I've checked options how to put a sand table on my hash gantry and it seems, I can simply put it on top of the existing printer. Just have to design the tool holders for magnets and some frame adapters. Easy to revert, when serious stuff happens on Slicer or FW side...

@o_lampe any news on your hash printer? It's been a while since you posted an update l and I am curious.

@oliof , thanks for asking.
I got a bit distracted by the NeoPixel situation I found in RRF. When I played with other controller options I saw a nice Ocean wave animation, which would perfectly fit the sand table theme.
Last month I bought a CO2 laser, which will engrave acrylic sheets with a wave pattern. Those sheets will be enlighted by the neoPixel wave animation.
Commissioning the laser took a while, it's still not perfect. In the meantime I try to find the best wave pattern for engraving.

//edit I also had the idea to put 4 Laser diodes (or even CO2 tubes) on the hash printer, they are not so critical with Z-height. But the firmware situation regarding multi-beam collaboration is even worse than multi-extruder collaboration.
I will ask the discord channel of the "K40Keller" if they like the idea...they helped me a lot with my K40.

Just for the record:
I will disassemble the frame, because another insane project is in the making and I need the space and some parts. It was a proof of concept study anyway and IMHO showed it's potential.
When the time comes and firmware and slicers are ready for it, I might rebuild it with linear rails and a stiffer frame.

@Amayaatp
technically, it's a cartesian printer with four printheads. Only 4 motors required for the XYUV gantry.
It allows several new and unique printmodes , which are currently not fully supported by slicers or printer firmware. So I disassembled it.

Maybe it will get a second chance in 5-10 years...

Hi. I'm the guy who did the "Hash Kinematics" video.

Landed here completely by chance while looking at the Dueling Zero Github (this post is referenced there).

At the time I've launched the videoI had a baby about to come and I that got me on ANOTHER (and more exciting) ride. Since then, It's harder to be in the right mental space (and money) to actually finish that build. That's why I'm really glad that video inspired someone to create something like this.

@_Djrema Hi, honored to have you here although my project ended early as a proof of concept only.

Slicers and controller firmware are just beginning to work with more than one nozzle, so it will take a while to see a working printer.
Another reason why I started the project is, the copy/mirror mode which was interesting at first. But since I own resin printers and learned their ability to mass produce parts, they are much more intriguing to me now.

Mirror mode for bigger parts would be a reason to build a #-printer, but the build-cost will explode.
