 Max Speed is set in units/second (mm/s or inch/s), depending on what units you have chosen in your G-codes settings.
+  * //NOTE: Overspeed acts in a manner  similar to CPU overclocking. Motion acceleration is increased together with motion speed when the overspeed is increased. Since toolpath planner does not have access to "Overspeed" value, a significant increase in Overspeed value up from 100% may cause issues, especially for analog servo control. Overspeed should be limited to 100% if you need to be sure the machine does not exceed "Max Speed".//
 . Set the Backlash in units (mm/inch) for each axis. Backlash is the value that allows for some unexpected play in the machine due to clearance or looseness of mechanical parts. When the controller sends a movement command to the motor, the motor may turn briefly before any actual axis movement begins. That turn is defined as backlash, and can be accounted for in this setting.

+=== Setting up a waterjet system ===
+Certain CAM software packages can automatically insert necessary waterjet M-codes at some desired distance from the corners to properly accelerate and decelerate the machine. These M-codes are M64/M65, as well as M164/M165 - the first two turn a specified output on/off on the fly without stopping (using the special FlyCut license that we provide), while M164/M165 are reserved for controlling the PWM output.
+Some profiles within myCNC software (such as X1366P) contain a Software PLC procedure (WATERJET_SLOWSPEED) that works by monitoring the state of the output that the above codes toggle on and off:
+<code C> main()
+{
+ a0=gvarget(7184)&(1<<10);
+do{
+a1=gvarget(7184)&(1<<10);
+if (a0!=a1)
+{
+ a0=a1;
+ if (a0==0) //normal speed
+  {
+   gvarset(9379,0);
+  }else //slow speed
+  {
+    gvarset(9379,1);
+  };
+};
+}while(1);
+};
+</code>
+The above software PLC monitors the state of the desired output and switches the state of the global variable #9379. Writing "1" to this global variable results in a timer being started in the myCNC system, allowing the software, with the help of "Overspeed %" value, to smoothly reduce/increase the speed while passing a corner.
+As mentioned before, this functionality requires a FlyCut license, which is available to purchase on request.
