OK, thanks. In the future it would be nice if the endstops were interrupts and any endstop (including E0/E1) could be used as an emergency stop (print stop) without resetting the board.
Just constructive feedback, I appreciate that I'm not paying you for this so don't stress about it. Thanks again!

No hardware e stop button I've ever used "restarts when released again" for a good reason, safety. Without exception they require positive intervention to reset the switch physically and require you to acknowledge in the control that you are recovering from an e-stop condition. Sometimes going as far as requiring a reset of the control. The last thing I would ever want is for a machine to begin running again once I took my hand off the e stop switch.Quote

... there are several "stop"-options with software and hardware:
- software - "Normal" Stop in software with Resume possibility - the G-codes in the buffer/queue will be executed before stopping
- software - "Normal" Stop in software without Resume possibility - the G-codes in the buffer/queue will be executed before stopping
- software - "Emergency Stop" per G-code "M112" - all motors and heaters will be shut down instantly ... restart with "M999"
- hardware - "Emergency Stop" - external emergency button, which shuts down the power ... restart when released again ...
