Saw this problem once before but he repair tech fixed it and I didn't ask him how he did it. I was testing my theory about fixed pockets(see earlier thread) and just running tool change programs through MDI without any tools in the spindle or carousel I made a tool change. The pot dropped down(this is a 30 tool vertical ferris wheel type machine, TNC426) , the arm dropped and spun to position then errored out, "toolchanger arm brake disengaged". Hit E stop, tried to reset machine, to no avail. When the machine comes on, can't initialize, error message "Toolchange arm not in position".
Anyone know how to get the pot to return to the horizontal position and get the arm to lift back up to home position?
