Axis lathe - showing velocity and DTG

Axis lathe - showing velocity and DTG was created by kentavv
Hi. In lathe mode (I've not checked mill mode), when I have Show Offsets enabled or am on the DRO tab, DTG is shown for the X and Z axes, but axis velocity is not shown. With Show Offsets not enabled, DTG and velocity are shown but not for each axis.
Is this the correct behavior (in case I've messed something up) and is there a way I can add axis velocities when Show Offsets is enabled and on the DRO page?
Thank you, Kent

That is a known bug.

OK, would fixing the bug be a reasonable challenge for a newbie or are there major obstacles?

Considering it has been that way for longer than I have used Linuxcnc (more than 8 years) it probably is not an easy fix.

Thanks Todd, that's too bad. It would be nice to find some simple task to tackle.
In case it's of some help to the next person, here's how I hacked it in for the time being. Seems to work with jogs and feed overrides, but not as nicely integrated as with mill mode.
custom_postgui.hal
custompanel.xml

This is actually a one line change in glcanon.py to get velocity to shown in the offsets page.
Is there a bug tracker for this problem? never heard of it before.
some where near line 1576:
If someome one could confirm the behavior I can push the fix

Hi Chris, I tried your suggestion and it worked perfectly. Looks much more like the mill mode does. I also learned about glcanon.py, which looks very interesting. Is it OK to modify this directly to add new functionality or is a there a recommended way that's safe from being overwritten during an upgrade? I have been using custompanel.xml and custom_postgui.hal. Thank you, Kent

This file would be overwritten on upgrades.
The typical way to maintain customizations of this type is to use a git clone of linuxcnc, create your own branch and run it Run-In-Place (RIP) - this is exactly what developers do.
In this way you can control what gets changed and when.
In this case when I get some time I will look to push the fix.
