Duet 3 Motor 23 CL or Stepperonline integrated servo

DuetUser

We had leadshine easy servo and DCS303 connected to Duet ethernet a few years ago.
Everything was fine only the prints were wavy distorted by layer shifting or something else and after some trial and error we dropped the project.

Now a new light shines, there are better Duet expansion possibilities and more motor options.
We need very fast travels on a large machines and total immunity to position loss.
There would be two ways, and I'm not certain if the second would work at all:

Just plug Duet close loop steppers (23CL) and forget.
We are stuck with stepper specs but with 48V it could be just enough, on the other hand the setup should be totally hassle free.
Try Duet 6XD with one of these: https://www.omc-stepperonline.com/integrated-servo-motor
and enjoy servo advantages along with a bag of extra troubles.

What are real life differences in two ways?
Do we lose on the servo side due to 5ms min signal length comparing to probably faster stepping rate with 23 CL?

@DuetUser Using one of the Duet closed loop products is without a doubt superior to using an external driver/motor combo.

Simple hardware and firmware setup
Integrated closed loop tuning & control
Better handling of error states

There is a third (and even a fourth option) you don't mention, and that is using the 1HCL expansion board instead of the 23CL steppers. This allows you to pick nearly any stepper you need, combine it with a quadrature encoder, and get running almost as easily as using the 23CL. The fourth option would be to also use a 1HCL, but in conjunction with the Duet Magnetic encoder. Depending on the motor you select, you may need to engineer a mounting interface for the magnetic encoder, but that should be fairly trivial.

If the 23CL motors don't quite get you the motor specs you need, I definitely recommend option three or four. Going the native closed loop direction and tuning directly in RRF/DWC is the way to go. https://docs.duet3d.com/User_manual/Tuning/Duet_3_1HCL_tuning

@sebkritikel Thanks, I'm concerned only about the motor characteristics of servos / steppers.
With fast long travels steppers have very little torque and are troublesome.
But on the other hand step dir is not a perfect solution to drive servos also.

There is little info about these subjects so probably we will go all Duet to save time and trouble.
