Connecting to a CNC machine, pros and cons of USB vs PP vs Ethernet etc.

Jess Enough now please your splitting Hairs to suit your unrealistic cause, again detracting from L.A.N problem.!!

From the perspective of my own experience, the distinctions I'm making are significant.

To try to explain: It's a bit like someone claiming you can do (arbitrary) under cuts on a vertical mill that has 3 axes. If you're a machinist, whether it's a 3, 4 or 5 axis job is a big difference, but to someone who just wants their design made it might seem like a trivial issue after all, it's 'just one more'.

Apologies for the detraction from the L.A.N. problem, though, you're absolutely right. I was erked by someone claiming a couple of decades of experience, but then, making the sort of error that should have been learned on day one. (Like if someone told you they had 20 years of experience as a machinist, but then couldn't explain climb versus conventional milling.)

Drop it sit back and watch this machine running on a CSlabs Ethernet motion controller doing all those things you say Ethernet can't do.!!

It's an example of moving the controller, so Ethernet doesn't have to deal with realtime demands (my point 2). Actually, you made this distinction really well earlier in the thread, when you referred to this kind of setup as 'Buffered not realtime'.

Very cool video too though! :)
