======PLC Includes for X1366M/M4/M6 series profiles======

=====mill_func.h=====

The mill_func.h features the lift_up as well as the coolant_motor_start code blocks.

===lift_up===

<code>lift_up()
{

  if (proc==plc_proc_spindle) //Lift if spindle was ON
  {
    z1=gvarget(17003); //Use the absolute program coordinates
    timer=10; do{timer--;}while (timer>0);

    z2=gvarget(7020); //Use the lift value
    z2=z2*100; //multiply lift value by 100, since PLC motion commands operate using 0.01 of chosen unit

    zmax=gvarget(17053)-5; //use Limit Z (in PLC motion command units)
    //(on older software versions which do not have Global Var #17053, can use #5433*100)
    zmachine=gvarget(17023); //Current machine coordinates
    zmax=zmax-zmachine; //Calculate distance to limit

    if (absolute==0) 
    {  //If lift in incremental mode, then check if lift does not go above limit and stop at limit in that case
         if (zmax<z2) {z2=zmax-5;};
