EMC2 HOW DO YOU SET MOTOR STEP ACCURACY

[Gads]

HI SETTING UP EMC2 AND HAVE GOTTEN ALL MOTORS RUNNING AND VELOCITY / ACCELARATION SET. HOW
WOULD YOU GO ABOUT FINE TUNING THINGS FOR ACCURACY AND REPEATABILITY. I WAS RUNNING MACH
AND YOU WERE ABLE TO DO ACCURACY/REPEATABILITY
TUNING. I HAVN'T FOUND ANYTHING IN EMC OR DOCS
SPECIFICLY POINTING THESE SETTINGS ?

ALSO MAY FIGURE THIS OUT BUT HOMING IS GOING THE
WRONG DIRECTION REGARDLESS OF TABLE SIZE HOME POSITION SETTINGS. HAVE PIN SET BOTH LIMIT + HOME ?

SO FAR SO GOOD
THANKS TO ALL.

Homing direction is controlled by the velocity value sign. If you want to home in the other direction put a minus sign in front of your homing velocities.

For screw compensation see here http://wiki.linuxcnc.org/cgi-bin/emc...w_Compensation

If your running at least 2.2.2 just use stepconf to set up your machine. It's on your menu under CNC...
