We are having some trouble with our nm200 mill. When running a program that requires coolant (m08) the spindle and all axis stop, and sometimes act erratic when the coolant pump kicks in. We have tried replacing the 12v relay that controls the coolant pump with no effect. We have also discovered that when the machine stops due to an m08 the mill has to be completely powered down for a few minutes or the spindle automatically turns on at full speed while the machine computer starts up...this causes a very dangerous situation. Do you have any ideas on what is causing this problem? With no wiring diagrams we are stuck. Any ideas?
