-Stepper Gantry basic configurations using gantrykins.
+Stepper Gantry basic configurations.
 
-gantry has no home switches
+It is very important for gantry machines to set initial home switch positions before first homing so they reach home switches at a very similar time. To remove any skewing on the gantry adjust the home offset of one joint. After homing the configuration will switch from joint mode to world mode.
 
-This configuration is a stepper based configuration for a gantry type of device using independent Y axis steppers on the gantry. When this configuration is started you will be in joint mode and each axis can be jogged independently. This allows you to square up the gantry to match marks then home each joint. Once this is completed switch to world mode before trying to jog the gantry.
+gantry_joints.ini uses the same .hal file but uses kinstype=BOTH which requires independently homing each joint axis.
 
-gantry-hs has home switches for each joint
+gantry.ini implements a dual Y motor gantry. This is the configuration to use after you verify the directions and speeds of the individual joints using gantry_joints.ini.
+
+These configs use switches for min-home on the X,Y,Y2 axis and max-home for Z. Pay attention to the parallel input pin assignment for the switches.
 
-This configuration is just like gantry.ini with the addition of home switches. Homing is done in joint mode. It is very important for gantries to set initial home switch positions before first homing so they reach home switches at a very similar time. To remove any skewing on the gantry adjust of home offset of one joint. After homing switch to world mode.
