Scale = steps/unit units = mm 200 motor steps/1 screw rev. x 2 (micro)steps/1 motor step x 1 screw rev./4mm = 200 x 2 / 4 = 100 steps / 1 mm so, your .ini file should have: ----------------- [AXIS 0] ... SCALE = 200 OUTPUT_SCALE = 1.000 ... [AXIS 1] ... SCALE = 200 OUTPUT_SCALE = 1.000 ... [AXIS 2] ... SCALE = 200 OUTPUT_SCALE = 1.000 ... ------------------ Unless I made a mistake. ... snip ------------------------------------------------------------------------------ BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA http://p.sf.net/sfu/rim-devcon-copy2 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
