Gmoccapy scaling up each time you exit tool table - 2.9.8 trixie was created by RotarySMP
Hi Guys,

I updated my lathe to 2.9.8 on Trixie with Preemt-RT. Now Gmoccapy appears to have a bug causing it to scale up each time you exit the tool table or the max preview. window size setting also doesn't work correctly, as the screen reduces in height when commanded to increase in either width or height.

I made a video to show the behavior. 


Like this, the lathe is nearly unusable, as I have to keep shutting down and restarting LinuxCNC to reset it. Any suggestions how to correct this greatly appreciated.
Cheers,
Mark

I updated my lathe to 2.9.8 on Trixie with RTAI.

I read that and thought "RTAI, resolution issues....", but nooo, you had to find something i have never seen, and it irrevocably seems a GmoccaPy issue.
This keeps reminding me of an American saying: never change a wining horse.
I am i am not helping.

Yeah, you warned me.

After I tried to update 2.8.2 I screwed something up, and decided I may as well then pull the SSD and do a clean install. 
If this is not easily fixible, I guess I could do a clean install of 2.8. and wheezy.
Cheers,
Mark

RTAI? isn't your lathe using a Mesa card?
Why RTAI?

Oops, my bad, I wrote that from memory and got RTAI and Preempt-RT confused, Rod. It is Preempt-RT I have installed. I'll edit that in the original post.

Hans contacted over the github bug tracker, to have me run the Gmoccapy lathe sim, and sure enough, there is no scaling error behaviour there.

So I also tried the Gmoccapy Lathe_Macros sim, and that has the scaling behavior error.

When I created my current config, copied my old 2.8.2 config files, and cut paste the lathe macro files from this sim. Any ideas where I need to look for corrective action appreciated.
Cheers,
Mark

Hans got me sorted out. I had an error in my INI.
He had me replace:
EMBED_TAB_LOCATION = ntb_preview
with
EMBED_TAB_LOCATION = ntb_user_tabs
Now it has stopped scaling.
Big thanks to Hans for getting that straight.
Cheers,
Happy Mark :)

It's not really an error in your INI file. The lathemacro just needs too much space for some reason and in ntb_user_tabs is just more space available ;-)

I just realised that the main Gmoccapy screen now behaves nicely. However, now I no longer have the tab for Andy's lathe macros.

You still have it - it just moved to the user tab section.
