As the subject says, I want a hardware emergency stop button. AFAIK, Pronterface doesn't even have an emergency stop button, and besides it's nice for it to be in hardware. I've got the hardware side covered, but I couldn't figure out how to wire it to the RAMPS. My first thought was to wire a switch to the reset pin. Apparently, though, RAMPS doesn't break it out -- it just wires it to the built-in button. Next, I figured I could use one of the endstop pins. I can't seem to find where in Repetier-Firmware I can set an emergency stop pin, though.

If the USB connection is still being used instead of the SD, power enough to keep the file alive is still there, but not enough power to move any motors.
Problem can be rectified if something simple like broken filament or a jam, and on restoring power the print can possibly continue.
It is simple and safe and also very cheap.]]> regpye General Sun, 13 Apr 2014 00:59:47 -0400 https://reprap.org/forum/read.php?1,338657,338938#msg-338938 https://reprap.org/forum/read.php?1,338657,338938#msg-338938 Remember, an e-stop is used for those "it's on fire" moments.
