Move Tool Change Location?

Hi Everyone! I'm new to CNC machining, and I'm stuck on a problem with my new lathe.

Smithy 1315 Lathe
with a Mesa 5i20 controller (I think)
Running LinuxCNC on the Ubuntu system that came with the lathe.

I wrote the code for my first part, which requires a tool change. I'm using T1 and T3 in the turret. Everything works fine with it. My concern right now is to speed up the cycle time. Right now, when I issue the tool change command (Tn M6 G43) the machine will move all the way to the machine origin (G54) before turning the turret. It's a long way from my part, and a lot of unnecessary movement.

How can I make my tool change happen closer to the part?

Check out TOOL_CHANGE_AT_G30

With this option, you can set the tool change location for your job by moving the machine where you want it and issuing G30.1
