How to disable preview in Gmocappy

Hello. I'm loading huge files (230Mbytes size) and on my cnc desktop rendering of these files are useless and it's painful for working.
Is there a way to completely disable rendering of tool path, and don't burn CPU resources?
 

You can try to hide it, but I am not sure if this reduces the cpu load (and if its even hidden). Insert this in the display section of the ini file:
EMBED_TAB_NAME = preview
EMBED_TAB_LOCATION = ntb_preview
EMBED_TAB_COMMAND = hide
For reference:
linuxcnc.org/docs/devel/html/gui/gmoccap...tabs-and-side-panels

add this near to top of program:

(AXIS,stop)

If I use "EMBED_TAB_COMMAND = hide" on 2.9 it hides the preview but also the file browser. I guess they display in the same "tab"... or something.

Meanwhile AXIS,stop seems to speed things up, allows big (15MB) gcode files, but I get this error:

Found an error!
The following information may be useful in troubleshooting:
Traceback (most recent call last):

load_preview
result, seq = qcode parse(f, canon, *args)

I see see error too, weird qtdragon doesn't get it (very similar code).
But (AXIS,hide) worked in Gmoccapy.

(AXIS,show) is available too, in this way you can hide/show different parts.

I think these special commands like (AXIS, xxx) should appear somewhere else in the docs than in the Axis page as they are relevant for some more GUIs.
Maybe in www.linuxcnc.org/docs/html/gcode/overview.html#gcode:messages ?
 

Maybe we could also add an option in the ini file to disable the preview like the guys of machinekit did:

groups.google.com/g/machinekit/c/xN_nHGH-Czo?pli=1
github.com/machinekit/machinekit/commit/...88e07eb6651bf10266dc

The docs there say:

• 'DISABLE_PREVIEW = YES'Loading big files can seriously slow down or even crash Axis if the preview is enabled,
  because it consumes huge amounts of memory.
  This option turns the preview off. The live plot will still be drawn.

It sounds nice that the live plot is still available.

That is a good idea. I recently added (PREVIEW,) as an alternative to AXIS to be more generic.

That is a good idea.

To which of my two posts is this related?

sorry, I was speaking of the documentation.
QtDragon already has this:
linuxcnc.org/docs/devel/html/gui/qtdragon.html#_preview_control

I have no strong opinion of your other suggestion, but if done it should be done for all GUIs so affects code in three files - but the code changes would be very similar.
