    My Master 2 is not working. When I turn it on, everything seems to work all right. When I enter the object that i want to scan, everything seems to work all right. when I start the process by hitting the red square the arm will go horizontally and when it gets to the middle it will stop and start vertically. It will travel about 3/4 of an inch and shut off. A sign comes on and says that it must restart. I have downloaded the newest software. I have gone to the support page and followed the instructions on testing. One thing is when I plug in the control, the fan never stops and the red light stays on. I signed up on forum last week and published my problem. I cannot find it on the forum. I was having trouble signing on until this morning. It seems that all sign on is working.

  2. I have tried several times to contact you and all I get is your computer reply…..
    I have tried all the steps over and over and over again…. I get a COMMUNICATION
    ERROR and the unit does not move on the gantry. The Laser and the fan has power
    but the servos don’t run/
    Do you have a test program? Can I replace the pc board or the complete unit?
    I really want to get this to work….
    Thank you
