    See the VFD section on docs.openbuilds.com/blackbox

    0-10v is pretty industry standard for VFDs, so it might

    But, changing the topic, what machine do you want to use this on? Its too big for our typical machines (frame needs to resist the cutting forces, deflection will occur)

    Peter, I have my own home-built machine (5'x 10') powered by openbuild parts (motors, blackbox, etc) plus the workbee 1510. Right now the larger machine uses a bosch 1/2"router that I had always planned on upgrading as time and success with the build proceeded. My new machine still has one small hiccup that I am trying to track down but even with that hiccup it still produces accurate parts. I have not been able to determine where the fault is but I am eliminating some possible suspects. To the point, I believe my new machine will be able to meet the cutting forces and deflection and as I move forward with my tests, I will have more and better data to help. I already have some "product" improvements in mind. The whole machine is belt-driven and I am looking at moving up to R&P for the y-axis and ball screw for the x-axis.
