[SOLVED] VISMCH delete old toolpath

1. Is it possible to delete the old toolpath in a VISMACH simulation rather than having to restart LinuxCNC?
2. As far as I understand tooltip = Capture() traces the toolpath but what does "work = Capture()" actually do?

Thanks

master branch:
github.com/LinuxCNC/linuxcnc/commit/7c4522a9


The commit is in the dgarr/s_kins branch too and incorporated
in the xyz[ab]c-trt-switchkins sim configs. I'll incorporate
for genser-switchins sims when time allows.

I tried to implement it.

Created a pyvcp button and added this to the ..-postgui.hal
net :vismach-clear <= pyvcp.vismach-clear => vismach.plotclear

But I get an error on startup
melfa-switchkins-postgui.hal:6: Pin 'vismach.plotclear' does not exist

So clearly I'm missing something.

The spelling should be right but maybe vismach is not yet loaded when I try to create that HAL-pin?








Maybe somebody finds something obvious.

melfa-switchkins-postgui.hal:6: Pin 'vismach.plotclear' does not exist

I think the problem is related to the fact that your stl
files are more complex than ones used by prior vismach guis
and there is a timing race related to the parsing of
these files and the execution of the postgui halfile that
connects the vismach.plotclear pin.

A workaround (without modifying the axis gui) is to
move the execution of the postgui hal file to an
[APPLICATION]APP=file as shown in this diff:

The DELAY in the [APPLICATION] section increases
the wait time for executing the APP file. The delay time needed will
depend on the complexity/number of stl files and the speed
of the computer.

Note: your post in _this_ thread included only some of the
files in the config so reproducing the problem required
finding files from other posts. It is more helpful to post
a zip or tar file of the *entire* sim configuration so that
the problem can be reproduced without additional file
searches.
