Greetings, Mach Fans!
I am working on a tool change macro for a Gantry style CNC router with a tool rack. I started with Brian's tool change macro, and tried to build upon it. I finally go it to do the correct motions I need. Will need some further configuration of outputs, dwell times, and speeds. I wanted to run this past the experts, and see if anyone has any tips on how do do this more efficiently.
I am including a picture of my non-standard tool grip configuration, to explain some (not all) of my madness. I will have two spindles mounted to the Z carriage, fixed relative to each other. Tool change will be simultaneous for both spindles, and they will be operating with identical tools (mass production... yay!) By positioning/spacing the tools on a rack this way, I will be saving space, as well as allowing for the simultaneous tool change.
It will be about two months before I will put power to this machine. Thank you to any and all who have comments on this matter. It is much appreciated.
