Length compensation for tool type (SD42950 TOOL_LENGTH_TYPE)
Value of the setting data equal to 0:
The behavior corresponds to the standard definition: The lengths 1 to 3 in geometry and
wear are assigned to the actual tool type (milling cutter / drill or turning tool).
Reference:
/BP_/ Operation and Programming
Value of the setting data not equal to 0:
The assignment of the tool lengths is always independent of the actual tool type.
Value 1: Length assignment always as for milling tools.
Value 2: Length assignment always as for turning tools.

SD42950 TOOL_LENGTH_TYPE =2
Explanation:
The active tool with the active D number always behaves as a turning tool in the length
compensation (-> SD42950 =2).
The length assignment is performed in all planes G17 to G19 as for G18 (-> SD42940=18):
Length 1 -> X axis
Length 2 -> Z axis
if Y axis exists: Length 3 -> Y axis
The tool radius acts according to the actual tool type and the active plane.
