I'm having a problem with the tool changer umbrella, the other day i ran a program that i've ran before and it went to change to tool 1 and it froze as soon as it got under the spindle. I checked the tool in and out sensors and all check good i'm thinking the motor that brings the umbrella to and from the spindle may be bad but not sure. is there any parameters or anything in the HAAS that i would be able to tell for sure if that motor is bad? Any help would be greatly appreciated.
