VB and the development of wizards / Re: Emco Turn tool changer macro

For those interested, I have just completed the electronics to use the original emco tool changer board and a MACH3/MACH4 compatible BOB (ESS/MB2 - from www.cncroom.com). Attached is a layman's schematic diagram showing you what you need to and how it all works. This diagram also shows you an example relay which I sourced locally in Australia from www.oceancontrols.com.au. Im sure you can find something suitable locally in your part of the world. You can then use the macro given in these posts for MACH3 or modify it for MACH4. You may want to add an additional OUTPUT to the macro to turn the ATC on/off. The schematic has 2 outputs (OUTPUT1 - on/off and OUTPUT2 - FWD/REV) with a diagram of the relay connections.
