This works, for other's reference, if you modify your UCCNC post, leave "use tool changer" unchecked during post processing, set your tool change position according to your machine coordinates (I use the same as my Park 1). In UCCNC make sure you have "Run the tool change macro (M6)" checked in General Setup. This will run tool changes via your M6 tool change macro but eliminate the M0 optional stop, and the machine will return to the tool change position ideally with material and parts out of harms way during the tool change. Awesome!
Thanks for your help, Gerry. I really appreciate it!
