I am having issues with the ATC spindle when it either releases the tool or picking up a tool. The drawbar clamp seems to be getting stuck. Its intermittent when it has an issue. I have ensured that the Z height is appropriate; however, with it having a releasing issue as well I am not suspecting that to be the problem. I have a little north of 95 psi showing on the gauge on the PE when I press the MTC button so I feel I have enough air. Could it be trash inside the spindle? My air supply has a filter on it so there shouldn’t be any moisture in it but I am in Alabama and there is a lotmoisture in the air so could that be it?
