Processing decimal separator question #6

Closed gpeter62 closed 6 years ago

gpeter62 commented 6 years ago

Hi Scott! I enjoy your fantastic code with my Polargraph machine. :) This is the best conversion from jpeg to gcode, I have ever used!!!

My question is: Do you know, how can I change the default decimal separator character in Processing 3? My local character is "," instead of "." and it is a problem in GCODE.

Other question: What is your suggestion, if I want to use 0.8mm pen? Which parameters should be changed? Thx: Peter

I just finished uploading a new version that can override the locale decimal separator for the gcode files. Look in the file "Drawbot_image_to_gcode_v2.pde" for "gcode_decimal_seperator" (currently line 29).

The pen width thing is something I really have not worked out in my brain yet. I usually set my image_size_x to 711mm and my image_scale() to 1000px. This ratio 0.711mm is about the width of my copix markers. So if take your image_size_x / 0.8, I think this is about what you want to set your image_scale to. If you get too much white space between your lines, and black areas are not covering completely, just increase your image_scale.

Hope that helps, and thanks for the kind words. Scott,
