Hello Chris,
The smallest step of my rail is about 2nm and good enough for me :-)
My current gear-box is 100:1

BTW, for the macro-photography I will use the gear-box 5:1.

Hello Chris, “Even if there's no gap between the gears, I'd still expect there still to be a measurable elasticity, depending on the force and number of gears, on change of direction.” Yes, for sure but it is too small for me. I don’t have the equipment in order to measure something in NANO-meters :...

Hello Keith,
Many thanks for the info!
In my case is very difficult to measure something because of the big translation.
Maybe you can find some information on the following site http://www.omc-stepperonline.com/

Hello Rik, According to the description of my gear-box it has a “backlash at no-load <=1 ° ” Probably it is a property of the motor because you have the same value. So, I only can observe some backlash during the changing of the direction of the rotation ( I can hear it :-) If the rail is driven in ...

Hi Rik,
This planetary gear-box contains very precise gear-wheels as in a Swiss watch :-)

Hello Chris, Spontaneously I would say there is no backlash in this solution :-) This gearbox has a capillary drive, finely graduated and the step-motor holds the position (the sluggish micrometer-screw too). http://www.photomacrography.net/forum/userpix/5394_nema17_gearbox_1.jpg So, the backlash is...

Hello everybody. Yesterday I received the LCD-shield and was able to complete my controller. http://www.photomacrography.net/forum/userpix/5394_Controler_1.jpg So, I have added the controller-slat to my macro-slat and have created the Macro-Station :-) http://www.photomacrography.net/forum/userpix/5...

Hello Chris,
Sorry, I have forgotten that :-( Full-frame, of course :-)
I have already tried to detect the magnification but I really don’t know how to determine the focus-range in easy way.
