I have 1.5.2 on Linux and I don’t see it either.
I went looking through the config section to see what I could find. The closest thing I could find was ‘Warn if bad file’ so I turned that on.
Then I changed a line in a G-code file from
G2 X0.095 Y-10.323 Z-1.500 I-0.372 J-0.076 K0.000 F2000.000
to
G216752 XYZABC0.095 Y-10.323 Z-1.500 I-0.372 J-0.076 K0.000 F2000.000
Then I hit the file reload button and I did not receive any warning. Okay, maybe it doesn’t work with a reload, let’s try closing gSender and starting fresh. I connected and then loaded the file and there is still no warning.
I also tried
G2 X0.0 95 Y-10.3 23 Z-1.5 00 I-0.37 2 J-0.0 76 K0.0 00 F20 00.000
and
G2 X0.0 95 Y-10.3 23 Z-1.5 00 I-0.37 2 J-0.0 76 K0.0 00 F20 00.000
#include <stdio.h>
int main(int argc, char* argv[]) {
printf("Does G-code allow inline C code?");
return 0;
}
G2 X-0.345 Y-9.887 Z-1.500 I-0.091 J0.348 K0.000 F2000.000
for bad G-code.
So unless the warnings are in a new super secret place I think something is broken.
