That's exactly what I plan on doing, stick them on and try. If 1605 doesn't work well for me, a pair of 1610 at 1300mm will cost an extra £100 + p&p so its not too bad. What I'd like to clarify, is resolution regards pitch, and micro stepping, and pulley reduction. here's the situations:

1. stick to my 1605 and gear 1:2 to get effective 10mm pitch but, will my nema23 have the torque needed for this gearing? I got the option to gear 1:1 when I need resolution,

2. buy 1610 and gear down 2:1 for high resolution, and stick to my nema23

3. buy 1610 and use micro stepping when high resolution is needed.

Thanks
