Design ideas finally drawn up for your opinions please

[Hopey]

Are you suggesting I shout use one stepper and a pulley set up on the x axis?

I'm not understanding the resonance issue, is it that there may be a resonance from the ballscrews turning that will be transmitted to the motor unless it is isolated mechanically from it?

I'll have a look for build threads by Eddycurrent and Kingcreaky with the aluminium gantry.

Cheers

Not suggesting using just one stepper for the X axis, choice is yours as two slaved drives work just as well.

If you connect the stepper directly to the ballscrew with a rigid coupling then any resonance transmitted through the ballscrew, from the spindle/cutter for instance, will be transmitted to the stepper, a belt will help lessen this.
