Installing duet 3d on stratasys fortus 350 mc machine

These motors are nema 34 https://www.radwell.co.uk/en-GB/Buy/ELECTROCRAFT/ELECTROCRAFT/XBR-2910/?redirect=true

@vaibhav123 do u recommend any driver that can be clubbed with duet mother bord

[vaibhav123]

@vaibhav123 can have a separate supply for the motors and drives

[vaibhav123]

@vaibhav123 I would rather prefer to define accel with duet 3d

@vaibhav123
You can get NEMA34 steppers, but I don't know what Duet / drive system would be suitable.

The people using Duets for CNC control are more likely to be using motors in that size and power range, I believe?

[vaibhav123]

Encoder with stepper motor would give the same performance with leadshine drives what is you opinion?

[rjenkinsgb]

@vaibhav123
These are another alternative, after some more searching!

Drives that accept step & direction signals, but work with BLDC motors!

They may give you the best of both worlds - Duet interface and the servomotor speed and torque etc.

I think that those motors are over powered for 3d printing because it will never reach half of its rpm it's corexy mechanism

[vaibhav123]

@vaibhav123 I still don't understand why they have a motor that can go up to 6000 rpm

[vaibhav123]

Because the belts and pulleys are similar to a core xy setup

[vaibhav123]

@vaibhav123 update it doesn't have limit switch for xy does have for z axis so it's like prusa stall detection

[rjenkinsgb]

@vaibhav123
Do the CoreXY axis drive belts go directly to the motor pulley, or is there some kind of intermediate gearbox or separate belt reduction between the motor and axis belts?

[vaibhav123]

@rjenkinsgb I can change the motors and drive but I need a recommendation from duet 3d that with expansion board I would have least problems

[vaibhav123]

@rjenkinsgb there is no gear box it is direct with four pulleys for x axis at each corner and 2 for y axis

OK, so it does not really need the very high speed motors to work, just the torque.

It should be possible for it to work with NEMA34 steppers that can be driven direct from a high current Duet board, or using those with external drivers / the existing motors with the Leadshine BLDC drivers, with a Duet that can output step and direction.
