W jaki sposób palnik wykrywa materiał- pływająca głowica, łuk pilotujący czy może inny sposób?

--THC on and off codes. Use nil if you don't want THC control e.g:
-- thcOnCode = nil
-- thcOffCode = nil
--here is another example that use M667 and M666
--thcOnCode = " M667"
--thcOffCode = " M666"

--This is the code to seek the top of the work
seekCode=" G38.2 Z-30.0 F600"
--You only need to set these if you are using a scriber
--Scriber X,Y,Z offsets in MILLIMETRES. Do not use inches here even if you want inch code
--Use the special code 'nil' on the Z axis to disable it.
--In that case no Z values will be output at all while scribing.
--e.g scriberZ = nil
scriberX = 110
scriberY = 220
scriberZ = 0
--scriber axis. Leave this as nil if the scriber is fixed to the same axis as the torch
--scriberAxis = "A"

-- created 1/1/06
-- Based on plasma1.post
-- Modified 21/6/2010
-- added option for 'nil' plate marker z
-- Added support for plate marker tool type as well as tool number based plate marker
-- Modified 4/11/2010
-- Added: Reference the torch on the first pen down if the plate marker is the first tool used.
