PROVerXL 4x4
- ? Spindle not stated
- Closed-loop
The PROVerXL 4x4 is SainSmart's biggest machine on this site, with a 1300 × 1300 mm (about 51 inch square) work area, ballscrews and closed-loop motors. It ships in six boxes for you to assemble, and an optional second Z axis is sold as an add-on. The page isn't clear on whether the 710W spindle in its spec table comes in the box, so check with SainSmart.
