Tool length. was created by Mike_Eitel
Hi I'm working on tool lenght and posibilities of using the probe input.....
I can show via pyvyp tool related values of halui. (X Y Z ) And expected to see the tool lenght on the Z axis....
But I see nothing and could not find another "pin" for the length
What do I wrong ?

Can you tell a bit more about what your doing specifically and what you expect to see? I can't understand what your real question is yet.

Sorry
THX John
I want to see the actual tool length( correction factor ) on my pyvcp screen
I hoped to get that from halui.tool.length_offset.z but that is not the value I expected to see.
I do it step by step. ( like milestones in a projekt)
First I wanted to see the langth value....
Than later develop a way ( via subroutine ) to implenet the tool length compensation.

What value did you get and what value did you see?
I assume that your doing a Tn M6 G43 to load the tool...

X Y Z stay 0
played a bit with G38 G10 tool table button, tool table edit and anithing that came to my mind.
I ecpected to see something from ( Mastercam .ngc ) some reaction an that H43 Hxxx code.
N120 T10 M6
N130 G0 G90 G54 X.945 Y-68.124 S1909 M3
N140 G43 H7 Z5.
But Nothing
Want to understand the different mechanism als
I'll do a screenshot and copy some code tommorow.
Good night and thx

If you open up the Show Hal Configuration window and put halui.tool.length_offset.z in the watch window
and in the MDI window do:
T1 M6 G43
G10 L1 P1 Z0.250
G43
or
G10 L1 P1 Z0.250
G43 H1
You will see the length offset for Z change in the watch window... assuming it was not already 0.250.

Good morning
Yes I start to see my errors. F.X missunderstanding the H in G43 ... It's not the length but the OFFSET im tools table
I start to understand that the N140 in mastercam lines:
( 10. FLAT ENDMILL TOOL - 10 DIA. OFF. - 0 LEN. - 0 DIA. - 10. )
N120 T10 M6
N130 G0 G90 G54 X.945 Y-68.124 S1909 M3
N140 G43 H0 Z5.
means: take the same tool as choosen in N120, and start at position Z5...
I missinterpreted as compensate by 5
What I'm looking for is G43.1 Z.. as dynamic lenth compensation, and yes, I see that in pyvcp.
THX John, again
