Mocha,
do you mean longer between the motor and the ballscrew so that you have more room for the coupling?

Hi Ian
It seemed like a really good idea at 3am this morning! lol, but I think I may have screwed up on the numbers.

The distance between the face of the motor and the face of the bearing for the ballscrew nearest it...
I'm working on the shaft of the NEMA 23 being around 20mm long and the coupling in the region of 34mm.

What I can't seem to calculate is the overall distance when it's all fitted together... I think it's around 60mm but that has some "guess" in it! Does it sound reasonable?

Can anyone point me at the right place to look or take a look at their set up and have a quick check for me please?
thanks!
