There does seem to be a fair bit of information out there on tool changing. This is a fairly recent post. [New to Tool Change, What's Missing?](https://forum.sienci.com/t/new-to-tool-change-whats-missing/10720)

Many notes tie back to @NeilFerreri macros – [CNCjs-Macros/Initial & New Tool at master · cncjs/CNCjs-Macros · GitHub](https://github.com/cncjs/CNCjs-Macros/tree/master/Initial%20%26%20New%20Tool)

And while I agree with the adage of “if it ain’t broke, don’t fix it” I do wonder if in the intervening 5 years and with the introduction of grblHAL if there are any desired modifications out there.
