I bought a plasmacam last week its used and i think its a 2002 it does not have dhc. i set it up last week and it worked good but it moved around ruff so i clean the tracks and clean the eletrical conectors with contact cleaner after i got it all cleaned up i went to intalize and the x and y motor went crazy they just move back and forth really fast and move all over then table
WHAT DID I DO@!

Probably got cleaner in the encoder wires or encoders themselves. The encoders are standard units but the wiring probably is custom. Also if the encoder wires got swapped then it would run away. If you are REAL unlucky you have blown something in the controller......be sitting down when you get the bid on a repair.

You plugged the motor encoder connectors in upside down.
