1 controller, 2 machines?

[frdfsnlght]

I'm in the process of building a router, but I also plan on converting a mini lathe to CNC soon. I just had the idea of building a single controller and using it for both machines. I don't plan on using the machines simultaneously. I had planned on using aircraft connectors for all the connections, so physically connecting the controller to each machine is not a problem. But I was wondering if a single firmware build on the controller might be able to handle both machines, with just a bunch of grblHAL setting changes. I plan on using the @phil-barrett Teensy 4.1 board (hopefully the newer version still in the works).

The main mechanical differences I see between the machines are:

• 4 vs 2 (or maybe 3) steppers
• number of limit switches
• lathe will have spindle encoder/index signals

Obviously things like steps/mm would be different for the axis, but that's a grbl setting. I think some of the limit switch stuff is also grbl settings. I imagine a "gcode" file containing the grbl setting commands for each machine. Once the controller is connected to a machine, I just run the appropriate file to set the controller to the right "mode" and off I go.

Is this possible? This could save me some serious money and space in my shop.

Is this possible?

As long as there are no compile time configurations that are different then this should work.
