My dad asked a facebook group for help decoding a calibration script I wrote for the new 3D printer, instead of just asking me, and every single person yelled at him that "oh that's so dangerous if you didn't write it yourself don't run it, if you can't manually write gcode sell your printer" etc.

why are these groups always full of degenerate assholes? (and why do they legitimately think calibrating a printer has to be done by manually writing bits to the EEPROM with a needle, or it's not worth having a printer?)
