I’ve been researching milling, cnc, and machining for the past couple years. I now work in manufacturing and use a cnc router everyday. I’ve been thinking, planning, and saving for a while and am currently designing my first machine.
First caveat! I don’t have an engineering background. I’ve learned a lot in the last few years but have to admit that when it comes to applied physics and more technical mechanical calculation I’m not confident in my understanding.
I’d like to use Odrive for my X, Y, Z and spindle drivers. I’m planning on using them in step/dir mode to allow me to essentiallly drop them into a standard cnc setup. Mach4 -> Smootherstepper board -> Breakout -> ODrives.
My first question is, “does that make sense?” Am I getting the most out of the ODrive by dropping it into a stepper setup? Is there a better way?
Second caveat! You may have guessed but when it comes to motors there is something that just hasn’t clicked yet. There are a lot of interlocking parameters, different standards, physics stuffs, and such that I just don’t have an intuitive grasp of yet.
If I’m calculating needing a top end HP output of <2hp at the spindle and if I’m using the smaller of the two ODrive motors to drive a spindle like this one am I on the right track?
I’m still in the design and sourcing/pricing phase so I would like to understand a little more clearly what I should be looking for in motor components. I’m drawn to ODrive by the closed loop nature, community and what seems like an auspicious platform to start building manufacturing tools around (I have plans for a 3d printer after the mill).
Thanks to anyone willing to advise or point me in the right direction for info. I’ll include a rendering of my current design. Still just a draft to work out size and component requirements, but feel free to criticize it! Please do, in fact.
