  Thanks for chiming in, I do appreciate it.  
  Then is it possible to string macros into a sequence to continually repeat until the layer is switched or simply unplugged? This device appears to have 15 layers in the QMK configurator so sacrificing one would still allow for a production device beyond a single purpose.
context: Is there a software available where I can check if all my switches are working? I use a tofu dz60rgb >
  
  You don't need software... you can just use an online checker, like the one on QMK config.   Or, just use a generic keyboard test site like this. >
  
  Do I need 2 knobs? or just 1 knob is enough?
  I want to buy keyboard macro (Macropad) and there is a choice: keyboard macro with 1 knob or with 2 knobs but I don't know other use of knobs beside sound volume and scrolling 
  (I think scrolling not very useful in knob if I have mouse wheel). So is 2 knobs are useful or one is enough? >
  
  That is a question only you can answer. In addition to some uses listed here, a rotary encoder can be used for several things:
  
  arrow up/down
  arrow left/right
  mouse wheel up/down
  changing layers on the macropad
  Photoshop zoom in/out
  Photoshop increase/decrease brush size >
  
  Thank you so much, I didn't know about that much stuff I can do with knobs. >
  
  Good Afternoon,
  Obviously new to the QMK side of things. Recently picked up a TIDBIT as a cheaper entry point into the QMK landscape to see its viability for my work. I am provisioning thousands of PC's a week and have automated a lot of processes with the Code v3 TKL and 104-key, to a lesser degree the Pok3r Vortex as well.
  My original purchase was made after looking at this thread here. The issue I hit is that the individual in question had linked his/her example and that link is now dead.
  Basically one of the key functions that I cant emulate on the Code v3 is repeating F2 or F12 for booting my systems (often 300 or so at a time) without someone actually hitting F2/F12. After sleuthing the net, this looks to be termed as "AutoFire", where you can toggle for a key to be repeatedly entered until toggled to stop.
  Any direction or assistance to achieve to this would be greatly appreciated.
  Thanks! >
  
  personally dont know of any kb or software that can do this . all kbs and software have a limit of how many times u can include a keypress in a macro even rapidfire style will have a time out of a min or so
