Q: I downloaded the files from the pen drive, then transformed it into txt with NETMASTER 2010 and brought it to the CNC. The figure was multiplied with repeated quantities and get stuck? 

A:The problem is caused by an error in the NC program ..
Check your NC programs second last line check if the second last line is G98.
M8
G40
G00X-2192.91Y-19.25
G98
M02
The G98 code caused the problem. Our machine is not compatible for this code.  You can simply delete the code and the program will be correct.
To prevent this problem from coming again do the following setting in your software.
