Excellent.
My Rapidchange ATC is a 6-postition tool holder and my fixed touch down probe is mounted next to the tool rack. If I tell the router to pickup any tools between T1 and T6 the spindle goes over to the tool rack and grabs the correct one. Then it moves to the fixed probe and measure it. That measurement then gets recorded in the tool chart. This way the software knows what tool I have in the router and its length.
If I type T9 then the software is set up for the spindle to NOT got to the ATC rack but rather over by the side of the table so I can manually load a bit that I don't have in the tool rack. After I do the manual load I hit "OK" and the spindle goes over to the fixed probe and touches down. So the software now knows how long the manually loaded bit is in relation to the others. As such I have 7 bits getting recorded in the tool length chart in UCCNC. T1 through T6 plus T9.
So in your case you just set the T1 and T2 ATC pickup locations as at the side of the table. Everything else works just like you actually had an ATC.
Here is a link to my YouTube channel showing the Rapidchange ATC in operation on my router.
