G92 vs. Keyboard END Key?

Hello,

I have an MDI command setup to touch-off different axis. Something like "G92 X0.000 Y0.000". I assumed this command was basically the same as selecting each axis and pressing the END key on the keyboard. Recently I used my MDI command via an on-screen button to touch-off both X and Y axis, but my screen image of the work area didn't update appropriately except for the axis readout resetting to 0.00 and I also received a warning that one or more axis would run outside it's limits if I ran the next job.

Pressing the END key for each axis successfully set LinuxCNC to the current position. Do I need to use a different code for my MDI command to duplicate the keyboard's END key?

Thanks...

Thanks John. I did not know that.

Thanks Andy. I'll have to look into it.

OK – I took some time to work on this. Probably a better way to do this, but I now have:


In the main .ini file:

In my custom_postgui.hal file:

In my custompanel.xml file:

My M101 file:

If I run M101 from a terminal, it seems to act correctly – Z axis 0's and the axis display reloads. If I click on the PyVCP button, nothing changes and a few seconds later I get an error that this can't happen in manual mode. I thought the halui.mdi-command-xx would put LinuxCNC in MDI mode, complete the script and return to (auto?) mode. I removed the line “axis-remote –reload” from M101 as a test to see if two commands created the error, but same results.

Is there something(s) I'm missing? Thanks in advance.

Have you tried using...

halui.mode.mdi (bit, in) - pin for requesting mdi mode

linuxcnc.org/docs/html/gui/halui.html

If you use a button to switch to MDI mode first.

Your MDI command could simply be...

MDI_COMMAND = G10 L20 P1 Z0.00

Thank you very much for this hints. I could do some further steps forward with it.
Now I can confirm the behavior of "axis-remote --reload" (delay and error EMC_TASK_PLAN_OPEN).

After some investigations, this worked for me as a work around (no delay and no error anymore):

Please pay attention to the "&" at the end of line.


Also following line for reloading worked:..but this will flash a terminal window at screen.

Hope this helps.

Thanks Holger. That now works for me too. I am familiar with the "&" which runs the command in the background and should have thought about that. I did not. Thank you!
