Yeah, I originally had the tool changer working with an 8 position rotary switch and push button to activate the tool changes. Then when you people taught me about Modbus I just too the switch function out of my ladder program and now Mach sends those commands to the PLC. SO I can let the gcode change the tool, or type it in MDI or still use the rotary switch, but now the rotary switch now does a tool change in mach so it's changing the tool number in mach and moving it to the correct tool change position.
I'm really liking modbus and PLCs, when you realize how easy it is and how you can impliment PLCs with it, the possibilities are endless.
Almost picked up TWO Fadal 4020 VMCs yesterday!!! Auction, perfect condition, went for about $5K each, one 1992 and one 1998. Rigging and transport kept me from buying them. $4000 from LA to SF. or $3200 for one sooo.... I really need to buy a 15K trailer so I can just rent a truck and pick this stuff up myself. They had some OLD but Working perfectly Kitamura Mycenter 1's, could have got one for $50.00!! But again transport.
