We have a Hurco VM1 that is a couple years old now and it has been acting up on us. We can use the machine and it will work fine. However after using the machine for a little while occasionally the work light will go out and the air in the spindle will quit. after doing this is gives a following error on the x-axis. and yesterday when it did this it jumped about .250 in the x-axis expectingly. I don't know if the light and the spindle air have to do with each other or not but it seems like they do. If anyone has any ideas of what might be causing this or how to fix it this would be greatly appreciated. Thanks in advance.
