+In this case, input g-code file is modified automatically to support tangential knife:
   - Positioning blocks (G0-code) is modified. CNC Control software looks at the next motion code, calculates motion direction angle and add C-axis rotation into the G0 code to follow the next motion.
   - For Arc interpolation codes (G2, G3) - CNC control add C-axis rotation to follow motion direction

+The #7005 variable can be set in Software PLC, "____HANDLER_INIT.plc".
+Software PLC procedure ____HANDLER_INIT is running at the start of myCNC control software right after a complete configuration sent to the controller.
+It's very easy to add a line to set the variable 7005 -
+<code>
+gvarset(7005,1);
+</code>
+For example
+<code C __HANDLER_INIT.plc>
+main()
+ {
+   gvarset(60000,1);  //run Servo ON procedure
+   gvarset(7005,1);   //Enable Tangential Knife control
+   exit(99);
