Morning all,
this is a two part question...
first off, is the most important, when i set a job away the machine moves to the start point, but the spindle does not start turning at all (two cutters down - i need to get this sorted). has any one had this problem and can it be fixed?
the second is... when i jog the machine to set the tool offsets, it sometimes sticks. after a good hoovering and clean it works. it seems to only happen when the machine has been stood inactive for a few weeks. although the machine is kept clean it seems to like a quick hoovering... what lubrication is best for the rails and "screw threads"?
Many thanks

1. If the spindle motor is on a plug and socket, make sure the plug is firmly in the socket
2. Check all the fuses are OK in the electrical control panel, check / replace one at a time as they have different ratings
3. Check power is getting to the spindle motor
3. Carbon brushes could be worn down
4. Spindle motor could be faulty.
Use a DRY silicon spray on the threaded actuator rods. Note some times the plastic female threaded drive nuts need fully removing from the threaded actuator rods and then given a good clean
