Ohmic Sensor Settings

The ohmic sensor settings is a function available in the PUMOTIX plasma module without purchasing additional options. The settings block can be found in the menu "Configuration" → "Settings" → "Plasma".

You must to put a check in front of the inscription "Use PLL-R2 ohmic sensor" before setting. It is necessary so that the program allows you to configure the use of an ohmic sensor:

1. Probing input (main)
   Input of the probing signal from the protective screen (cap).
2. Probing input (reserve)
   Allows to correctly complete the probe task if the main probing sensor didn't work for some reason.
3. Enable output
   Output for switching on the ohmic sensor measuring circuit.
4. dZ correction value, units
   The distance when lifting the cutter before triggering the reserve probing sensor. The height adjustment is applied automatically when the backup sensor is activated.
5. Torch Detachment input
   The G-code executing is automatically stopped with the corresponding message when a signal is triggered . You can continue from the stop position after restoring the cutter position.

For easy setup, the fields and scheme are connected by links showing where a particular sensor element is located on the torch. 

The dZ value can be measured by measuring the distance in millimeters or inches on the device itself manually and entering the value in the program, or automatically.

The automatic method for calculating the dZ value is implemented using a special macro that calculates the distance between the first and the reserved ohmic sensor. To implement this macro, it is necessary to connect and configure the first and reserved ohmic sensor (Probing and Probing2).
Calculation algorithm: it is necessary to descend along the Z axis, fixing the coordinate values when the Probing and Probing2 sensors are triggered, calculate the distance between them and set this value using SetOmichSensorDelta(number) function.
