TouchOff

Hello...

I want to be able to make TouchOff from signal from pendant.
But looking in manual I can't find the working way.
If I click touchOff in axis gui everithyng works..
What sequence the axis does when is touchoff pressed?
I try to mimic that in MDI mode but no succes.
It shoul be something like G10... but after hour of reading manual and triing I give up and post that question...

the real connection is probably done halui way.
[HALUI]
MDI_COMMAND = G10 ????
and triggering halui.mdi-command-<nn> pin

any help?

Yes a G10 as a mdi command would be what you want. Without knowing what your wanting to touch off I can't say which G10 is the right one.

I wan't same functionality as the button TouchOff on axis gave me. (the only difference is to be executed from hal pin, and the offset to be constant and not entered value)

try using

MDI_COMMAND =G10 L20 P0 X50 to set x to 50
MDI_COMMAND =G10 L20 P0 Y20 to set y to 20

This (I already tryed) set coordinate to 50 20, but does not work same as TouchOff in Axis.
When LinuxCNC is started there is LinuxCNC text in preview window. If I jog Z axis to let say 50 and do touchoff (and enter 0) the DRO show 0 and part "LinuxCNC text in preview window" jump to that base.
if I enter G10 L20 P0 Z0 instead clicking TouchOff the DRO show 0, but the part "LinuxCNC text in preview window" stay in same place.

Touching off to material.

As John's example above shows that does what you are trying to do.
The AXIS display will change to reflect the results when you load or reload the g code file.

Normally I use a button on my pendant issue a similar MDI command to set my Z height before loading the g code I wish to run. This way the results are shown.

Hit the reload button on AXIS
Use the keyboard short cut [control R]
