Hi Steve,

I haven't actually got around to working it out yet - but unscientifically I'd say about 3x what I was getting before...

M8 rod has 1.2mm pitch, whereas this leadscrew has 3mm pitch, so a 2.5X win there...but now the motors aren't turning so fast (operating a the better end of their torque delivery - so I'm reckoning there's win there too!

... to mention way less overall nois and erhm less drive screw 'wobble' - my previous M8 threaded rod was marginally warped! I'm sure I'll have less backlash too versus my crap homemade delrin nuts!
