I spent one full day trying to get the touch plate to work and I was not successful.   I read the entire other thread on the subject and tried everything.   So here is what I followed, one wire of the touch plate on port 2 pin 13 with a  4.7k resistor on pin 13 and 5v.   I have the ESS set to low.  Without anything touching the touch plate wires the probe led on the diagnostic is illuminated.   I tired other resistors with the same result.  The only way I can get the led on the diagnostic screen to go out is by running a jumper from the 5v to pin 13.    With the 5v running to pin 13 the touch probe will work until it hits and then the ESS loses communication due to power interruption which I am assuming is probably not good for the board.    Also without any wires connected to any pins when pin 13 is set to low the led on the diagnostic board is lit.  If I set the ESS pin 13 to high the probe led on the diagnostic screen works perfect when putting 5v to pin 13 but obviously this won't work.

I am using the C25 BOB and an external power supply.  If anybody has any ideas or if more information is needed let me know please.

I have an issue with Mach 4 which I am unable to resolve.   It runs fine through about 750 lines of g-code and then starts to surge.  I have a link to a youtube video and its around the 25 second mark.   https://www.youtube.com/watch?v=VVcAZpRVGns.   [img]http://i11.photobucket.com/albums/a167/S76911Driver/1pocket.jpg/img]  Here is where the gcode starts this issue.http://i11.photobucket.com/albums/a167/S76911Driver/1pocket.jpg.    I am using windows 10.  I'll provide more info if anyone can help.
