What would you build if you were starting again now?

Railcore or Voron. Jubilee if tool changing is what you're after.

Thanks all, interesting.

So coreXY is the recomendation of all. I am surprised the cross gantry didnt get more support as it seemed like an interesting way to go and I was thinking it would likely be more stable.

Other than that it looks like everyone recommends what they have ,pretty much ,so it looks like you are all happy with what you are using which I guess says a lot about how far things have come over the last few years

I would build my large delta all over again. In its present incarnation it's been almost hassle-free, which I can't say for any of my other printers. But I am looking forward to fitting it with a larger and CAN-connected Smart Effector carrying an Orbiter extruder.

@opentoideas
if you wanna build futureproof, go for a # hash-style printer. It is cross-gantry like the CroXY, but with 4 toolheads, so you can make use of the upcoming multi-stream gcode feature.
Even better if you design a printer with 4 independent tools working synchronously

@all
why has no one mentioned a Delta? 300x300 build volume isn't too hard to build (OK dc42 has beaten me)

Looks interesting!

Is something like this in development? Sounds interesting.

It's planned, but there are more important pieces of hardware for us to develop first.

All?

Unless requested I won't be building a CoreXY again.

Speaking of deltas, (I have a SeeMeCNC Rostock Max V3.2 which uses a Duet2/Ethernet)

SeeMeCNC build a 300mm Delta for US$1,500 and a 500mm !!! Delta for US$4,500. Both use Duet.

I like its symmetry.

It depends on what you're interested in. If you just want a machine that prints with minimal effort and you have the funds, buy a proven machine/kit.

If you're interested in the details of how the machines work and maximizing some specific types of performance, I would design and build from scratch. It takes time but you learn a lot along the way, including modeling in CAD, mechanical design, machining, where to buy parts, etc.

@mrehorstdmd
And 2 or 3 years later with the 2. gen of that machine it will be reliable...

I would make a few small iterative changes to my current design. Actually, I will be making printer number two soon with a few changes:

Drive the Y axis only by one side instead of both. Currently I use a ridiculously long primary belt to drive both sides of the Y axis. This causes unnecessary backlash because the primary is as long as the secondaries (lol. I know now.) I will just use a short primary like on X. Hopefully this immediately solves the backlash on Y (it's in the order of <100 microns of backlash)

@dc42

I have to say I agree, though IDEX and core-xy are really tempting.

I have a SeeMeCNC rostock max v2 that I built from kit in late 2014 as my 1st (and still only) printer. The early days were constantly alternating between joy and intense frustration.

I have updated most every aspect of it over the years and now have a printer that I really enjoy. When I get tempted by Voron videos and the like, I just think about how easy my delta is to work on. I can't see any other platform being so simple, accessible and quick.

So like you, I would build another delta, only bigger with an all metal frame!

@dc42 does that new SE plan also include an integrated accelerometer? Surely there's room!

Yes, of course! Although my delta exhibits very little ringing. Basically it will be a combined Smart Effector and Tool Board, although we will probably leave out some of the additional IO pins.

@zapta I hate the gantry. 'U' shaped. Personally I think there is tooo much happening with it. I think I should of built the 1.8 where X/Y is static and the bed moves...
And Klipper. I updated it and Klipper threw a its rattle out of the pram.
IMO with Klipper and SKRs, everything is a workaround. Did try Klipper on a Duet2/Duex5 on the RailCore and the Bed level hardly worked. Back to RRF and worked everytime...

@phaedrux Friend of mine has his own toolchanger on a Voron 1.8

Agreed.
