CNC milling specials like cutter compensation are nice and dandy, but useful for manually written programs, only.
I'm thinking more about work offsets, probing (not the z-bed kind), tool tables, etc... CNC without support for toolchange is extremely painful.

I thought we were talking about milling here. Machines coming with a tool changer (what a luxury) most likely have a firmware already, no need to replace that one.

work piece placement is always a variable, even if it can be worked around if you know where the part is relative to machine travel BEFORE programming.

Believe me, I've done this hundreds of times and never needed a tool changer or "responsive" jogging or cutter compensation or length offset or whatever reasons you try to find here for keeping people away from milling.

it just doesn't make sense to recommend 3d printer electronics for milling when there are alternatives which are more suitable for the task.

This is RepRap, so hobbyists, no production environment.

Didn't expect to have to explain such simple things to people talking about production environments.
Work piece placement isn't a variable. X and Y is known from the cutter before, for the first cutter a rather coarse placement is sufficient. Z is simply set (see the hint on G92) after touching the workpiece with the cutter manually. Instead of adjusting tool length one simply moves the coordinate system. Tooltip == Z0 at the touching point is easy to remember, so one generates G-code for that. Has always worked, from ancient non-CNC mills to MAHO with Phillips 232 controller to modern Homags to hobbyist machines like WolfStrap or Mantis.
It's disappointing that such discussions are needed to get feet of owners of $100,000 machines back down to the floor. Such discussions shy people away from tasks they can perfectly do with the tooling they already have or with low budget investments.

At the hobby level you still toolchange since machining with one cutter isn't a ton of fun. Generally the program will pause and raise the spindle so you can manually swap the tool. If your toolholders repeat in Z you can just look up the new offset and continue; otherwise you can probe the new tool against a height setter and then continue the program.
