So this machine has been running Mach4 with the ESS for sometime now.  I just upgraded it to Mach4 build 2223 and the ESS plugin on the Warp9 website.  This plug in was a little newer than the one i had installed.  See the video for my new issue.

That ticking sound is the relay on pin 1 of port 1 when the y axis is jogged (pin4 step and pin 5 dir).  Pin1 was being used for the reverse signal to the vfd, that is now disconnected, and I uncofigured pin 1 in the ess plugin and the output signal in mach4.  the video is in that that, nothing should be doing anything on pin1.  the spindle doesn't work at all now.  very annoying.  this all worked fine, foward and reverse prior to the update.  my assumption is something is screwy in the plugin.  anyone experienced the same thing?

In a bind now, have parts that need to get made NOW.  I should know by now not to upgrade prior to a job, but mach4 really needed to be updated.

Thank you for any help and ideas.

problem solved.  thanks greg.  appears there was a bit of a bug in the plugin.
