Hi,
I have an EDM orbit simulator
written in python and displayed with tkinter.
I'd like to use a stock LinuxCNC gui instead,
but ran into scaling problems.
Tiny circles cannot be zoomed to fill the view port.
Edn orbits are tiny, less than 300 mictons.
If you load the code (below) and try to fill
the AXIS display with the path, you'll see clipping
before the path gets large compared to screen.
Any ideas how to zoom closer in AXIS?
Any other guis more 'zoomable'?
3 pngs attached.
The orbit screenshots show the tool ctr
motion in blue. The radial lines are escape
motion for low voltage while cutting perimeter.

I use axis, 2(lathes) or 4(mills) axis setups, have not encountered
anything resembling the first 2 images below. And I do use quite high
magnifications from time to time. 2.10.pre on the older wheezy/intel
installs, 2.9.something on the rpi4b for the Sheldon. The only obvious
shortcoming is too small a buffer while running complex deeply looped
code resulting in the red trace disappearing from the display as the
code I wrote works its way thru the loops. The white trace remains, so
I'm guessing video buffer limits someplace it the display chain. It has
never affected the results.
Thx tomp
Did not test this code, I'm currently snowed in, the garage back door
opens outward with 2 feet of white stuff drifted in and blocking it and
cannot get into the garage to check if its safe to home my machines. I
don't recall what might be on the table blocking homing motions. Icicles
5 feet long hanging from front deck gutters. Hope you're having better
weather.. I haven't turned a wheel in 9 days.
