Hello everyone. Found the forum. Great site. I recently purchased a Rabbit HX6090SC. got it home worked great. The second time I used it the power supply blew. Fan inside was un pluged and over heated. Received a new power supply but not the same. Same wattage but for one of their other machines. They said it would work. Have it installed the way they want it but the laser fires just won't leave the tube ! The laser seems to arc at the metal ring whrer you make the connection for the ground on the laser tube. Any Ideas ? Any one ever hear of this ? I replaced the laser tube with a spare I bought, same thing. Any help would really be great. Thanks, Jim
