Totally agree with that. Even though I've only powered the Z on my South Bend Heavy 10L my ELS has been so handy for not only those occasional metric threads but I haven't clamped the bed stop now for years.

All done with the MDI. Should really have done the G-Code but it was a one of test thing. 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.
