               Plasma CNC Torch Height Controller.

  Dani THC11DP (Dir/Pulse input /output interface with anti - dive function ).
                       Principal of work :
 Plasma machines use a constant current power supply for cutting steel. While the current of the plasma cutters is constante (adjustable by operator ) the voltage changes, when the distance between the torch tip and the metal plate changes . When the distance between the torch and cutting plate gets farther, the arc voltage increases and when the torch comes close to the plate the arc voltage will decrease. The Cutting torch voltage  can range from 10 to 400 volts (or more) depends of the Plasma cutter's  model. The Torch Height Controller (THC) ,will constantly measure the voltage change and will keep a constant distance between the torch and cutting plate by sending a signal to the  Motorized Z axis driver to go up , or  down.
 Dani THC uses internal Voltage Divider, build by high quality components to bring the  torch high voltages to a readable safe values and precision filters to protect the CPU from high-frequency interference coming from the cutting torch
The THC  calculate the reading values and converting to a control signal for motorized "Z" axis ,Dani THC uses latest generation microcontroller (Atmega328) with adjustable 9 parameters , using 2 friendly buttons ,3 LEDs corresponding to the output signals(Ark ON, UP,and DOWN),3 digits 7 segment led display(solit and high frequency resistable).        Dani THC is built with the highest quality components to ensure a safe, durable, and reliable long term operation.

DaniTHC11DP(Dir/Pulse) is a stand alone device .It can control the "Z"axis driver directly without using Mach3 or computer by sending control signals straight to the driver ,to move up or down ,with adjustable speed.
DaniTHC7SDP is Suitable for use with Breakout boards non supporting THC( like USB or LAN serial communication).

The working principle of Dani THC11DP(DIR/PUL with anti - dive function ) is as follows:
When the plasma torch is off and not engaged in the cutting process (during probing or positioning), the THC (Torch Height Controller) is inactive. In this state, the Z-axis movement is controlled by the computer (Mach3). The THC does not interfere with or affect the Z-axis movement during this time.
However, when the plasma torch is on (during the cutting process), the torch voltage activates the THC (Torch Height Controller). In this state, the THC takes control of the Z-axis and maintains a constant desired distance between the plasma torch and the metal plate. The THC continuously adjusts the Z-axis movement based on the feedback from the torch voltage to ensure the proper height is maintained throughout the cutting process.
                             Anti -Dive Function  Principal of work :
A reduced feed rate is often used  when cutting small holes or  tight angles. This diminished feed rate can lead to an elevation in arc voltage, potentially causing the  THC to inadvertently lower the torch into the workpiece. To avert such instances of the torch descending into the workpiece during reduced feed rates, it is advisable to deactivate the Torch Height Control (THC). For a temporary deactivation of the THC, you can utilize the Anti-dive function on the
   Dani THC11DP.
