C-axis (Coupler) is not homing properly and I cant get it to grab any tool. It dose move when I ask it to but I dont understand why it is not homing properly, Lock and unlock macros are not working too. My Guess is that when homing it, the rotation stop is not in the correct position but i can not figure out why, any help is appreciated. ps: it did work once when I was building the system. I only had one tool setup then.
