Argh Probably because he's got a pile of 32mm screws he wants shut of.!! . . . You won't find many other reputable builders recommending 32mm screws with a single central screw at this width and using steppers.!! . . . . . However You will find many machines this size running 20 and 25mm screws without any trouble.

Also 3Kw will easily push cutter thru MFC at 19mm with correct cutter/size but if your in no rush what does it matter if it's done in 2 passes.? Proper spec'd machine will do 2 passes quicker than one only capable of 3500mm/min.!

By the sounds your sold on the machine anyway, so no point saying anymore really other than good luck.!
