General Mach Discussion / Mach3, servos and no motion controller
« on: June 11, 2013, 05:35:28 PM »
Hello,

I'm thinking about the construction of my first router. A gantry type, about 6x3x1. As versatile as possible regarding usage.
I live in Argentina, here is very difficult to obtain and import equipment so I must choose very well.

I'm considering Mach3 and I have some questions.

As I understand Mach3 works as a trajectory generator, open loop. So Mach3 does not care about the motor-drive combo as long as they accept pulse & dir. It could be open loop steppers, closed loop steppers or servos. Is that correct?

If the above is correct I'd like to use servos (closing the loop only in the drive, no motion controller), and I see some AC servo & drive economic options. I am considering the following alternatives, and would like some feedback on them and other options in the same price range.

At the moment my preferences are:

AC servo & drive

closed loop stepper

open loop steppers

I am new in this area and any advice is welcome.
Thanks and regards,

Martin
