Q: I am having a machine in my demo room, I fix a pen in place of plasma torch. I have set the CNC to plasma mode, But ever time when I press green button to start the machine will not start moving, it shows the PIERCE ON in the controller. The timers keep running, if I press the green button again it will star moving. 

A: This problem is caused by setting , You must have enabled “ARC FEED BACK” this is for plasma cutting, the machine will not start moving until the ARC feedback from plasma is reached.Since you are not using the plasma machine you have to set it to zero for the machine to work normally.
 
SETUP[F4]-----PLASMA[F4}--------Set ARC FEED BACK(1/0)  to “0”
