I use my Midi all the time with my Bosch 4410 SCMS, and I plug the saw into the Midi’s outlet.
The saw is a 3hp 15amp motor, and has never bogged down the Midi.
I got a short 36mm 2-meter hose and it does indeed provide much better dust collection. There also is a ‘technique’ for cutting on a SCMS that facilitates better dust collection, versus the straight plunge down.
