My HAAS VF2 is making a grinding noise during a tool change. I made a video of it. You can hear it during the second tool change. Its like a grinding squeak when the drawbar pull up the tool holder. It will also pause in the middle of a tool change and take 2-3 seconds till it pulls up the drawbar and pulls out the tool carrier. I have searched for this but I am only finding threads on the tool holder popping out of the spindle. Any help would be appreciated.
