It's about my Maho MH500,
forum.linuxcnc.org/42-deutsch/42077-maho...-plugandplay?start=0

running with linuxcnc 2.8.2 and gmoccapy.

Beforehand the machine was configured with this basic configuration.
forum.linuxcnc.org/30-cnc-machines/41442...tion?start=20#204531

so started with Axis, and then only changed to gmoccapy in the configuration.

What I noticed now is that after the homing the wrong DRO is displayed first
 
G58 is displayed, but with the machine coordinates on the right. If I really want to see g58, for example, I must first call a g57 and back again aug G58, then the DRO output is also correct.
Have googled , on github I have found exactly such an issue from 2016.
github.com/LinuxCNC/linuxcnc/issues/157

The next thing would be the tool change.
works fine , but with the axis window.
 
Probably because my configuration was only changed to gmoccapy, from axis.

Afterwards I have to look again at the connections in the Hal and compare them with a gmoccapy example
but at least with the DRO story I'm quite at a loss


My configuration folder is on github
github.com/DoWerna/maho_retrofit/blob/master/basic7i97.hal
github.com/DoWerna/maho_retrofit/blob/master/basic7i97.ini
github.com/DoWerna/maho_retrofit/blob/master/custom_postgui.hal

and the entire folder
github.com/DoWerna/maho_retrofit

Just test renamed the .var .pref files and restarted the machine.
Unfortunately without success the DRO still shows the wrong values at startup.

Only when I run a G55 and G54 the G54 values are displayed.

Did you try in [RS274NGC] section to enter a startup code with the desired UCS
RS274NGC_STARTUP_CODE = G0 G17 G21 G40 G49 G55 G80 G90 G92.1 G94 M48

Yes
I have just inserted the line.
but has unfortunately brought nothing.
After homing, the Abs coordinates are always displayed in the DRO, although the values in the DRO are labeled with G55.

to see the real G55 values you need a G54 and then G55

in the githubissue the problem was solved by recompiling everything.

What I have done so far

sudo apt remove linuxcnc-uspace
sudo apt autoremove
sudo apt install linuxcnc-uspace

so linuxcnc including dependencies deleted and reinstalled.

This has brought nothing

Possibly it has similar reasons with me,
I started the machine configuration with 2.9 from the buildbot, my 7i97 was not supported by 2.8.
have then later changed to the stable 2.8.2...

wiped through a bit again

sudo apt purge linuxcnc-uspace
sudo apt --purge autoremove
sudo apt purge mesaflash
sudo apt --purge autoremove

sudo apt update
sudo apt dist-upgrade

sudo apt install linuxcnc-uspace-dev
sudo apt install mesaflash


Now it seems to work :-)

apparently not after all

after the reinstallation everything worked.
after homing were always immediately displayed the correct values in the DRO.

Have now switched to the Gmoccapy Toolchange window...

I have really only edited the configuration files and started some previus configs for testing

now shows me after the homing again the machine constants, instead of the selected G5X coordinate system.

Am I really the only one with this "problem"?

Of course, this is not really a big deal now.
You only have to call up the coordinate system again and the values are correct.

I would find it only strange that with me a bug occurs, which has no one else.

Means for me that I have somewhere an error in the configuration or installation....

I do not see any error in INI or hal files. It is very strange, that your machine starts with G58.
Actually I have no time to get deeper into this, but I will have it on my to Do list.

What hapens if you start a sim config?

Maybe delete the linuxcnc.var file? Possibly that has an accidental persistent entry.
