Looking for information on probing for new tool length after tool change

Hello everyone. I'm a hobby linuxcnc user on a hobby level machine which does not have an automatic tool changer. From what I've read in the docs and randomly around online, it sounds like linuxcnc is designed more with pro-level use in mind so an ATC is assumed. Unfortunately for me, that means as far as I can tell there isn't really a built-in way to tell linuxcnc (or the fusion360 post) that you need to probe for a new tool length when a tool change occurs. My way around this has been to just group toolpaths by tool and post them individually, which means if I have 5 tool changes for a part I will need to run 5 different programs for that job. This is working well enough, but it seems really inelegant and I'd love to be able to just post the whole job and let the machine probe the new tool automatically. Could anyone give me some information on how I could set that up, or point me towards that information if it already exists and my search skills have just failed me?

For reference, I'm using gmocappy as my UI and my machine is XXYYZ.

This is exactly what I was looking for! I had it in my head that I was going to need to pretty much write it from scratch so I didn't even think to check the gmocappy docs. Thank you!
