[Emc-users] I've got a few questions on servos

[Wes S <we...@ac...>]

Hi,

This is my first post to the list. 
I want to cnc something.  I have not decided if it is going to be a 
lathe or mill though I'm leaning toward the mill. Likely a X3 type of 
machine.  I don't think I want to CNC my bridgeport or clausing 
lathe.

Years ago I used some Galil DMC720 controls to make machines to put 
hot melt on package trays before turning the edges.

I also used IMC 110 controls and another IMC , I think the 4xxx with 
GML to make machines to fly srim dispensing heads into forming 
presses.

Each time I used servo motors instead of steppers.  I understand how 
steppers make things much simpler, if you don't lose step, you can 
just keep track of steps.

I personally don't like open loop.  I know you can use steppers and 
encoders but I don't see the benefit there over servo motors.

If I'm not totally off track, I understand EMC can take encoder 
feedback.  What boards are typically used?  What drives are usually 
used in servo apps?

I have a lot of questions but I'll stop there.

Currently I repair cnc equipment and other automation.  I know a bit 
about a lot of things and know I don't know enough about much.
