Galil / Re: Which servo amplifiers?

Have you thought of sticking with the Fanuc DC drives..they are very cheap to buy on Ebay these days and the Fanuc manuals are very in depth on how to set them up.I am at the point where the machine just needs to be reliable. It is 26 years old and in the 3 years that I've owned it, I've had more than my fair share of gremlins and downtime. I have intermittent 401 alarms (among other random problems), which could be the drives, the wiring, the controller, etc. - I just want it to be reliable. The machine is finally making some money and I cannot afford to have it randomly drop out. By gutting everything, I can be sure that I get all of the gremlins. Plus, the project will be a bunch of fun.
I've found them to be very reliable...
On the Fanuc system (I presume you have 6MB??) the encoders attach to a frequency to velocity circuit on the motherboard to give speed and position.Yes, it is a 6MB. I will be using Galil DMC-2153 controller (the extra axes for future projects, such as a rotary table) connected to three AMC BE25A20AC drives. I haven't checked if the Fanuc encoders are 5V TTL style. If not, I will retrofit some USDigital units on there. It won't be the first time I grafted different servos onto a motor...
I'm fairly new to Mach..how will you set up the encoders, i'm asking as I have a Galil DMC 1880 that I would like to set up with Mach3 and the Fanuc yellow cap dc brush motors.
The project is on hold for the summer (too busy), but once I get started, I will begin a blog.
Thanks for the interest,
Chris
