I usually tell people to make a gun with their left hand - thumb points to positive Z, index finger points to positive Y, and other fingers point to positive X.
Hmm, the drawings above show
coordinate spaces for the motors, not the extruder, that's why the second drawing shows the origin at the far left side and not the near left as you mention. I edited the post to clarify that. Here is the drawing with a
coordinate space for the extruder, with the end stops corrected accordingly:
- Extruder coordinate space (RepRap convention)
The Y axis end stops may seem wrong to an outside observer, but for an observer siting on the gantry (i.e. the extruder) Y min is achieved when the carriage moves to the back of the bot.
mxk, thanks for the comment!
