    Very good. Actual measurements of accuracy, repeatability, max force, and max speed for different actuators. How difficult would it be to include some Rack and Pinion measurements?
    On a somewhat related note, has anyone published the flex of various linear rails of common lengths?

    For the more visually oriented among us (and you know who you are):

    Nice graphs. I have to ask about the Nema 23 screws, are they ACME or ballscrew? If ballscrew, what diameter/pitch?

    Interesting. It would be interesting to see the test done with a double belt setup (one into the other). In theory, it should improve at least the repeatability of a single belt setup ...

    I would love to see that tested too as double belts made a huge difference in cut performance but hard data like yours would blow my mind!

    I'm not (currently) using the double belt setup having good results with the standard single belt. But as I progress with use of myOX, I'm thinking of extending the Y from 750mm (Vslot length) to at least 1000mm AND going to double belt. I have to stop making free signs ("practice" runs) first.

    If I can recommend only one upgrade to ANY ox/belt pulley user it would be to double belt it. It makes SUCH a HUGE difference that IMHO should be done on any length axis. The hardest part is finding a good quality double sided tape that can stick to both rubber and the rail. Too thick and you wont get the two belts under the wheels.
