Our VMX 24 went to do a tool change today when I got an overload fault half way though the tool change. The center post of the exchange arm is down about 1''. Just enough to where I can't get the tools out. I pushed the reset in the back cabinet and cleared the alarm on the control panel several times but to no avail. The machine is just 2 month's out of warranty. Any ideas as to whats going on here??
