@matt3o looks like you're getting awesome results! Well done on persevering with it, that pain is now knowledge...for the next one

it's funny because it's true I'm already thinking of building a very small one...

Hi,
again nice to read about projects.
Great machine, month ago I was looking at annex cross cartesian while wondering what to build for a project with large ABS parts, in the end built simple core XY with linear rods and triple Z with leadscrews, I end up using Oldham couplers for the motor - leadscrew coupling. But this one looks great
I remember you from Peopoly forum with the moai battle. We all ended up with LCD printers at the end

@matt3o Great! It looks like you've got the extrusion tuned up nicely!

That's really a beauty! I started to design a new CoreXY for high temperature printing, but this is too much problems for my needs, so I will build a new 'simple' machine. And why not try a new geometry?

As I also work with Onshape, this is a good oportunity. I won't build such large machine, 250x250x250 will be enough.

BTW, is this geometry more rigid than a CoreXY (all things equal)? With 2 carriages at 90° for the tool head, it seems it can handle more lateral efforts. I'm very interested in 5 axis printing, and mounting a tall and heavy head on such geometry is maybe better than on a CoreXY...

What do you think?

@fma

I built a similar but much smaller (200 x 200 x 200) printer.

I like the motion system a great deal - simple with short belts.

My prints just fine.

we don't talk about that....

I find it to be better in every possible way. More precise, sturdier and stronger (let's not forget there are 4 motors for XY).

The downside is that 1) you need more components 2) everything needs to be perefectly square so a little more time spent assembling it up.

If you need to put a lot of weight on the gantry you can use bigger backers for the rails, but of course you are adding weight.

Thanks for the feedback!

@matt3o Which fysetc board did you end up going for?

@matt3, nice build!

Here is an upgrade idea for you (Double Agony) https://www.youtube.com/watch?v=tzf8903FvCs

@lael hey sorry for the late reply. the forum didn't notify your reply.

They are FYSETC S6 V2.0 today I would probably get a Spider.

@zapta OHMYGOD I need it!
