X-50 1610 vs. 1616 Ball Screw

Is the 1610 Ball Screw slower, and more accurate than the 1616 Ball Screw?

I see you offer both now on the site, and I just googled this to learn that the first 16 = diameter, and the 10 or second 16 is lead, or thread “height”. So if the 16 lead is longer, and faster, and the size of one step from the [beefier] stepper motor is the same per rotation, does that necessarily imply it is more or less accurate?

I’m pretty new, and interested in making several very small, intricate things and speed has no value to me. Precision does. Should I buy the 1610 X-50?

From what I understand the accuracy of both will be more than enough for woodworking. I am using a different controller, where you can use microstepping to change the number of steps per revolution - I imagine you can do the same with Onefinity. I think it depends on what you mean by accurate. My Woodworker is modified to some degree and I am finding my backlash on most axes to vary between 0.02 and 0.03 mm. I believe all stepper motors have a small inherent error (+/- degrees). Add to that the precision of the ball screw assemblies (Onefinity has yet to get back to me on the precision rating of their linear motion hardware), router/spindle runout, etc… and you will have even more error. For this hobby level machine I think the accuracy is very good, but I hope others with more working experience will add their findings and opinions as well.

Hi Bob - I agree with @TMToronto - it depends on your precision and accuracy needs. I’ve found the repeatability of the machine to be very high, and accuracy much better than my previous X-Carve. You can adjust the steps/revolution with the OF controller to tune it as required, but that really only affect accuracy not precision or repeatability.

Hope this helps.


I didn’t realize there was a way to adjust steps/rev, nor that there’s a difference between accuracy and precision, so that’s super helpful. Thanks to both of you @cyberreefguru and @TMToronto !
