I have been collecting stuff from ebay, and am now deciding on how to proceed. I have all the ball screws and servos with encoders, a Galil DMC 2040 4 axis controller with an ICM 2900 pinout or whatever you call it, servo amps, power supply, a 4 foot air slide, but am lacking a few support rails. I also have a spare Fanuc 90-30 PLC and the Versa Pro software to program it.
I muddled through the PLC programming to get another tapping machine (with a 90-30) running, so am familiar with ladder logic.
I have been reading the Galil users manual, and it's even more confusing than the Fanuc manual was. But I need real control on this x-y table - hence the Galil.
This machine, and x-y table, I hope to expand to include screw insertion under another head - hence the 4 foot long air slide.
The more I think about it, the more it seems to make sense to use BOTH the PLC and the Galil, since the screw insertion operation is likely to be using a lot of sensors and a lot of inputs and outputs.
Does anyone have any thoughts on this? And has anyone combined the two in the past with good results?
I made adaptors for two of the ball screws last week, and have mounted the servos. One is hooked to the Galil and I can make it move in sequential moves now. By sheer cooincidence, one encoder count equals .001" of linear travel. I still don't know how to actually write a whole program and get it into the controller, then push a button and have the thing do what it's supposed to. But I will hopefully get to that part within a couple weeks or so.
But those kinds of questions are for later.
Thanks.
