I have a Smithy 1324 MAX and was looking at CNC options. I came across the link to the 1220 conversion above. It is using direct drive steppers at over 1000 oz in on ball screws.

The kit that Smithy sells for over 4k only has 424 oz in steppers and I assume they have you using the factory screws. I have also noticed that they have a kit to attach the motors via pulleys and belts that seems from the pictures to be a gear reduction. It may be that the Smithy kit is just very slow??

Can anyone comment on what they used for a motor screw combination?

Thanks!
