I am trying to bring up a new CNC router and am using the PMDX-126 BOB, PMDX-134 motherboard w/G203V drivers, the USB SmoothStepper, and the PMDX-107 spindle controller. Several E-stop switches are wired in series to the PMDX-134 and the function seems to work normally when Mach3 is not running (meaning the led on the BOB reflects the condition of any of the E-Stop switches), but when Mach3 is running, hitting E-stop causes Mach3 to shut everything down appropriately, but hitting the Reset button on the Mach3 screen doesn't clear the E-stop condition. In fact, the led on the BOB stays lite regardless of whether or not you clear the switch (or hit the reset button on Mach3). What is keeping it active?? Any suggestions would be much appreciated!
