solved crash when bit is too big

[grumpy]

using dxf2gcode-20220226_RC1
with "cutter compensation" not checked in configuration
if i select a cutter that is larger than the object and select "cutter compensation" g42 dxf2gode crashes
i tagged this unsolved even though i know the solution
don't do that

Traceback (most recent call last):

However your right, this should work. Can you send the file and the parameters you used to reproduce the bug. Otherwise it will be difficult to find it ...

not sure what all you need
open file
select circle
select cutter #2
right click on circle and select cutter compensation g42

Hi grumpy,
just checked that. You want to mill a diameter of 4mm with a tool diamter of 6.35. Thats the bug, right? this will just crash, your right, no failure message at all ...

I added a change in the code to detect the topic if no geometry left after compensation. Please check link:
dxf2gcode / SourceCode / Commit [569615]

that is a big improvement
it doesn't crash so i have the chance to fix my mistake
it does go ahead and set g42 cutter compensation
with your change after i set g42 with and oversized bit if i select "pocket mill" the program crashes
a novice like me can easily miss the error message and spend a lot time chasing this


when i was working i could write a nice little program in 100 lines
it would quickly turn in to 10000 lines trying to make it idiot proof

That's the way it is. But my intention is not to make it 100% idiot proof ....
