The most important maintenance step you can take is to "ghost" or image your hard drive. Having a spare, pre-imaged IDE or SSD drive allows you to recover from a crash in minutes rather than weeks.

The 640M power supply unit (PSU) must provide stable, precise voltage. Measure the +5Vpositive 5 cap V +12Vpositive 12 cap V -12Vnegative 12 cap V
Control environmental variables like back-lash compensation values for the X, Y, and Z axes. If your machine is losing circularity during a ball-bar test, adjusting these sub-micron compensation parameters can restore geometric accuracy.
