 +//**NOTE**: The myCNC team recommends utilizing the examples provided in this manual (as well as other manuals in this documentation) as a starting point for your machine setup. When possible (and applicable), it is recommended to keep changes to a mininum. In general, using these examples as the basis for your PLCs/macro commands allows for an easier setup process.//

 +=== How to set up a Multi-Tool Tangential Cutter ===
 +
 +FIXME //Section under construction//
 +
 +For tangential cutting, a common scenario is for the system switch between two different motors for both the Z and the C axes (to switch between the tangential knife and the creasing wheel, for instance). Therefore, the system will have: 
 +
 +  * X- and Y-axes motors
 +  * Two different motors for the Z-axis (for knife and wheel up-down movement)
 +  * Two different motors for the C-axis (for knife and wheel rotation)
 +
 +**1.** How to switch between motors:
 +
 +**Axis pulse-dir signal** can be connected/disconnected from **Motor output** by writing to CNC registers 0x70...0x75 (112...117)
 +  * 0x70 (112) - Motor output #0
 +  * 0x71 (113) - Motor output #1
 +  * 0x72 (114) - Motor output #2
 +  * 0x73 (115) - Motor output #3
 +  * 0x74 (116) - Motor output #4
 +  * 0x75 (117) - Motor output #5
 +
 +Low 4 bits (0..3) of the writing value represent Axis to connect - 
 +  * 0 - X
 +  * 1 - Y
 +  * 2 - Z
 +  * 3 - A
 +  * 4 - B
 +  * 5 - C
 +  * 15 - disconnected
 +
 +pulse-dir Direction will be changed (**DIR** signal inverted) if Bit #4 is set.
 +
 +This way we add PLC procedures M201 and M202 to switch Z axis between Motor outputs #3 and #4
 +
 +<code C M201.plc>#include vars.h

 +  parameter=2+16;   //Attach to Z-axis, "16" is axis inversion
 +  command=112+3;   //motor output #3
 +  message=PLCCMD_SET_CNC_VAR;
 +  timer=2;do{timer--;}while(timer>0);

 +
 +=== 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.
