Manual tool change + tool lengh touch off

It looks like the TLO is calculated correctly but it seems that my job-file resets this offset immediately when it starts milling again.

I looked into my gcode and i found that after every tool change
The exact command is inserted in the gcode after every tool change. Is it correct that is always uses Z15 and also H1 for every tool?
Somehow I know it can't be the problem but why is it there? :blink:

Thanks a lot in advance guys!

Sorry - it means that the offset that's currently stored in G54 after touching off the workpiece is now somehow the same value shown in the TLO.

That might not be wrong.

That's a G43 H1 and a Z _move_ to 15. G43 does not take a Z-parameter.

Hey Guys,

I recorded the screen of whats actually going - maybe it's easier



The video starts after I touched off the material and I issued the M600 before the file starts. The TLO is 0.
I placed the second tool deeper in the spindle and the calculated TLO is -2.263mm which would be correct as the Z-axis moves negative to the table.
Then the milling starts, TLO is shows 0 again and the tool is above the workpiece. Pretty much the height of the first tool that was a bit longer outside the spindle.

I hope this shows my problem :whistle:

That's the problem. G43 H1 will reset the tool offset that the touch-off set, to be the tool offset stored in the tool table for tool 1.
By removing G43 H1, all should work well. I don't know if you want to move to Z15 at this point. Maybe not, in which case the entire line can be removed.
