I'm betting on power supply just fixed a lathe a couple days ago same prob, a new on from hfo is 350.00$ and it will replace two of the power supply's and will power the mocon boards making the machine a ill more simpler. Sounds like the power supply is taking a sh$& they will be bad at 11.5 volts the mocon boards and video boards are picky. Also check your dc buss should be around 340 vdc and check to make sure the machine is phased right this is vary hard on the machines drives, andddddd also check to make sure the 230 voltage is on the right taps on the main power supply in the bottom right of the power cabinet. Hope this helps

Mike, is there any correlation between temperature in the shop and when the machine works / doesn't work. In cold weather, metal shrinks. Think solder joints, etc.

Just an idea.
