Got the Workbee 1010 LS up and going. Everything works 100% EXCEPT the limit switches and homing cycle. I checked, double checked, and triple checked all the wiring and connections and the GRBL settings. I used my Fluke Meter to check continuity from switches to controller. All of that is fine. The "Trouble Shooting" in the Openbuilds driver shows no response from the limit switches, even when the switches are manually operated. Nutshell.......fishing for any ideas. Thanks!
