💡 why does a cnc spindle amplifier overheat and cut power during heavy feeds
Fixing sudden servo failure is usually a handy shop job when you trace back the root electrical stressors. Most machinists replace the blown board and get the rig back on the floor without touching the main controller.
- Worn filter capacitors let ripple voltage fry sensitive switching transistors
- Blocked heatsink vents let exhaust air pool and trip safety thermostats
- Skipped terminal torque allows arcing friction that eats connector pins
- Frayed motor cables feed dirty feedback signals into the error logic board
