    Hi,

    As the subject says, the pen is not going up or down. The servo moves when I click on Pen up or down, and I can see the G code set is G01 F300 Z10 and G01 F300 Z90, however, I saved the gcode of my art to a text file and checked it and the servo is being sent G01 F50 Z90. Why is the software sending two different codes?

    I am using an Arduino uno with a Adafruit motor shield v2.3.

    OK. The servo is moving, butthe first few commands seem to be failing…

    and it is not using the values I specify in the Pen settings. I am using Up: 90, Down: 10, but it is sending this code for Pen up: G00 F50 Z50;*60

    I found that after modifying the settings you need to restart the program, otherwise it wont take the new values…

    Aaah… actually, you can re-load the image file and it will take the new values. if you create gcode A, change settings, and then create gcode B for the same image with the same settings, A != B and A will be unchanged.

    If you can think of a good way to make this more obvious, let me know. I will add it to the program so nobody else trips over my less-than-perfect code.

    Oh… So the G code is being generated when the image/art is created… Hmmm… How about saving the last image load/art generation parameters into memory and just re-do the last operation when the user changes the settings? That may no work well for generated art since some of them take a lot of time to generate… If that’s not possible, maybe just show a reminder to the user.

    Jose, you have good ideas I’ve considered. I didn’t pop up a reminder because I felt it was annoying. Long time regenerating pictures is exactly the reason I didn’t make it automatic. I have not found a happy middle.
