I still have to install Ballscrews an mount my motors so I might try to wait it out

@dc42
Is the duet 3 capable of driving the motors directly?

@jay_s_uk

That’s ok, I’m not in a rush. In the meantime I want to keep building so I’d like engage with you on the rest of the system so I get it right.

Can that be done offline? It would just be easier is all.

Also, to clarify my intent.

I’d like to get a complete kit from you that will allow me to build a multi use control panel that will allow me to move my motors between a number of machines. Mill, lathe, router, 3D printer, scanner ect.

I’d like to be able to setup machine profiles in the software to drive the different systems.

I’ve probably gone overkill on the (350w x4), drivers and motors and installed them into a mobile cabinet.

I’ll be installing breakers, surge protection and line filters into the panel.

Your system seems to be very intuitive and from what I’ve seen if it could be done then you’d be the people doing it.

I’m happy to incorporate anything you think appropriate to ensure a good outcome.

Thanks and regards

Dave

Thanks Jay, any idea as to when the duet 3 will be released?

Hi, I have a 1.5kw mill running 4x NEMA 34 12nm motors and drives. I really like your platform and was wondering if you have a suitable board for my purpose.

Dave
