I just used the Pi4 LinuxCNC version to do some simple slotting. All done with

It's there that I realized yet again that something between the capability of
the Pendant which is very handy and the full CNC would be really handly. Kind
of an ELS-MILL. Fancy power feed so to speak.
It’s the little things tha trip me up. Like setting the spindle to 1000 RPM.
Doing some cutting and then sending an MDI command like G01 X0.0 S500
And the spindle stopped. Seems once issued from the MDI it doesn't know that
there was an M3 kind of there from the user interface speed setting. So it
stopped. Had to hit estop before the cutter hit the work.
Silly things like that.
Yes, there are a number of rough edges to linuxCNC.
Starting a program in the middle, it does a lot of stuff to
get the machine in the right state, but doesn't start the
spindle. You have to do it with an MDI command.
