For any of the Calmotion products, if the G-code programs are setup correctly and the correct steps are used, the Calmotion will continuously and automatically repeat a program during DNC.
The CNC program needs to end with the correct end of program M2 or M30. These codes will end the program and put the CNC back into "WAITING" mode.
Next make sure the DNC mode of the Calmotion unit is used. The DNC mode will automatically send the same program file over and over again. But the end of program G-code must be in the program file so that the CNC stops at the end of the program. Otherwise, the program will run over and over again.
Note: On the Fadal products, there is an option to only disable the automatic repeating of the same file. This is only for very specific instances. Do not use the DNC=ONE TIME feature unless there is a reason to do so.
