Yes I agree. Have you decided on one motor or two?

Don't buy any electrics until you have it all drawn up in CAD AM882 or EM806 work well for the drives at 68V

Dear Clive S,

My design dictates at least 2 idler pullys per ballscrew if i want to go single x axis nema 34 stepper... and have the whole bed space.

Or... i have to limit bed space and cross the bed...There is room in the design to do this though.
And 1 side is up against a wall anyways.

When going single stepper,
i think i would buy a wide stepper pully,
and shift the ballscrews a belt width and use 2 belts, 1 for every ballscrew.

For now a 2 stepper x setup looks more convenient from a mechanical point of view.
2 short belts.
lots of bed space

My Electronic pov is opposit.

For inertia it seems, in my mind, better too.
2 powerful 3+Nm steppers on high voltage digital drivers. Instead of a single bigger 8/12nm nema34. this is just a gut feeling , not based on any sound research.

Not sure what makes a 3, 3,1 or 4 Nm nema 23 stepper best choice.
Just high amps low inductance right?



Any thoughts?
