Hi, sburrell
I've had a few struggles over the last two years;
- failing HDD (replaced with modern SSD)
- failing BIOS-memory on RT-motherboard (snipped off original battery, and soldered on dual AA-holder for ease of later replacement - set sufficient settings in BIOS)
- seized servo motor bearings (due to storage in unsufficient environment/temperatures - replaced)
- servo drive failing due to aging internal passive components (caps, resistors etc.)
- other strange behaviour (cannot remember exactly which ones) solved by reseating boards and relays.
Other than that - great machine!
