Had a search of posts and I think this is mostly right, but wanted to understand if I pieced it together right:
In terms of the maximum theoretical feedrate (ignoring the actual cutting), the max feedrate is about 2500mm/m?
And the limit in the hardware is not being able to retract / extend the belts faster than that?
And diagonal travel is the place we see the limit forst because that’s opposite corners feeding / retracting straight on?
And this is supposition: 2500mm/m is based on the diameter of the reel with the belt fully out and the max voltage the motor should be driven (or is it more about the gearbox)?
Again, spot on. A few versions back we re-wrote the kinematics software to better account for this so in theory now we can allow faster moves in directions that it’s physically possible, but I haven’t worked on testing that yet.
I figure the 60RPM was a sweet spot in terms of various tradeoffs, but as I like pushing the hardware in various ways, I was pondering what might happen if we used the next one up or down in terms of gearing.
Like, if I limit myself to 1/8 bits doing 1/8th cuts, would picking the the next gearing up (85RPM) make sense - it’s less torque but faster, and I think there’s headroom as long as you had free spinning / well lubricated reels.
And similarly, if I’m trying to do a full sized spindle, maybe the 43RPM gearbox might make sense, though I’m suspect belt stretch would mess things up
