[FIXED] V5 MakerGear M2 E Stop Not Working

[shinji008]

Just upgraded to V5, and the E-Stop button in Machine Controls no longer works. Per the communication log, it is sending M112. Printer seems to ignore it, does not reboot, or stop any in progress actions.

MakerGear M2 V$ (24V). Works fine in Simplify3D V4.1.2

See Log Below, expect reboot after M112.

The M2 runs Marlin doesn't it? That's very odd because M112 is definitely the correct command to send. See here:

I wanted to let you know that Version 5.0.1 was released this week with some improvements to the emergency stop button for your MakerGear printer. It should now do a much better job of stopping all actions in progress when the button is hit.
