I think I found a problem. I thought K2 was using Pin1 which is really Pin 14, which also can't be used if using a PMDX-107. After re-wiring to K1 Pin 1 which I thought is machine enable, it did nothing. My E-stop is also wired in series to the coil.

SmartBOB controllers and dedicated accessories / SmartBob-411 & 126 K2 Relay

I've recently replaced my ESS with PMDX-411 Smartbob but am having a couple problems. I decided to ditch the ESS due to several homing and limit switch issues not being able to jog when limits hit. 

I'm running Mach4 Build 4.2.0.2763 with the latest PMDX-411 Smartbob Build 0.31.147. I'm using a PMDX-126 and PMDX-107 on a 3 axis mill. My mill has a total of 5 limit switches.

One limit for Xhome/X+/X- (Pin 12), One limit for Yhome/Y+/Y- (Pin 11), One limit for Z+ (Pin 13), One limit for Z- (Pin "E"), and One limit for Z Home (Pin "F").

I've configured the PMDX-126 dip switch settings to run in Expanded Input Mode as cited from the PMDX-411 documentation. All three Leadshine DM2282 Stepper Drivers and Hitachi WJ200 VFD are wired into a magnetic contactor which coil is activated through the K2 relay (Pin 1?) on the PMDX-126. Within the plug-in, I do have expanded inputs enabled. After booting Mach, when I "Enable", the K2 relay coil closes for a second, then opens, and then I lose total communication on the Smartbob to Mach. JP2 on the PMDX-126 is set to "Multimode", and Config8 is set to "Open" (126 Doc. says closed for Exp. I/O + Exp. Outputs which i've tried for shigiggles). 

When I first installed the SmartBob, I had the PMDX-126 configured as normal state with charge pump and the smartbob plug-in with the Gecko option. I did like this with the ESS, as K2 would enable during Mach load  I had several issues with the motors, adjusting various settings, which resulted into tuning the steppers via Leadshine's software. So far I have X+Y running smoothly. I was unable to activate the spindle for the past 3 nights fiddling around but most importantly I need to resolve the expanded mode problem first.
