Hi,
I'm building full metal IDEX Cartesian printer - all parts milled.
Build volume will be 510x510x700mm.
Will use Duet 3 with toolboards. Love the idea - only 3 thin wires and 2 power wires.

Bed will be kinetically coupled with three independent z motors.
Want to archive non print moves about 400-500mm/s.
It's not easy task, but making rigid frame and wide gates belts i think i can do that.
In my actual small Cartesian i can easily archive 450mm/s as non print moves. Only flaw of this is that i must from time to time change belts. But it's working.

But i got dilemma with right motor for Y axis.
I was thinking about NEMA23, but regarding motor inertia it could be problematic.

Here's my first version of new printer. Don't take seriously some ideas. It's some kind of idea, but as usual in my case over complicated.

Most important here Y axis. As you see, I'm planing use here 2 12mm Gates_LL belts and one NEMA23.
But reading some post on this forum, i see that with NEMA23 it will be problematic to archive such speeds.
I'm thinking about Nema17, but I'm little afraid that it will handle it.
Have you ideas how solve that problem ?

Hi,
main question - what is steprate of DUET3 mini and DUET3 ?
Were looking and didn't found.

Second question regarding upload speeds.
Got DUET2Wifi and upload speed is not the best, specially it's long process when you upload big files.
Often my files are over 150mb.

I was looking for alternative for 2.4Ghz modules and found RTL8720DN which is 802.11 a/b/g/n.
Will be possible to adapt to DUET2 or duet3 mini such modules.
