Slic3r 0.8.2 and new randomize starting points feature

[ghost]

Slic3r 0.8.2 on windows 7 seems to be great so far for me.

One slight thing - the new GUI option to "randomize starting points" in the GUI works in reverse. ie. if it is ticked then it does not randomize but if it is unticked then it does randomize. I think this is backwards.

To replicate the bug, view the generated gcode in a gcode viewer (I use repetier) with and without this option ticked.

An other problem with the same parameter is that it isn't possible to change behaviour from command line. I called it with these two version:

and always got the same result - no randomizing. The only way to get it randomized is with external config files where randomizing is disabled. My guess is, that it is am associated bug with the one above. No option -> off, option --> reverse -> off

[alranel]

The option's logic seems to be working straight for me.

@repetier, yeah, that's a design flaw for options that are negative by default. I'll introduce a --no- prefix to disable them.

[repetier]

The --no prefix is ok, but the problem is I can't enable randomize with the precompiled version. So with this logic --no-randomize-start would then enable randomize. Have you inverted the logic since the 0.8.2 release so that it is working straight for you?

[henrikbrixandersen]

@repetier I can not reproduce the issue you describe, where --no-randomize-start would ENABLE randomized start. Can you please verify if you still have this issue with 0.9.1?

[repetier]

The new version stores the configuration in an ini file, so I don't have this issue any more.
