I try to add a rectangular (try also with 3 point) to my working configuration, allways at startup the smoothie fail with :
#leveling-strategy.rectangular-grid.enable true
#leveling-strategy.rectangular-grid.x_size 100
#leveling-strategy.rectangular-grid.y_size 100
#leveling-strategy.rectangular-grid.size 4
#leveling-strategy.rectangular-grid.human_readable true
##leveling-strategy.rectangular-grid.do_home true
##leveling-strategy.rectangular-grid.probe_offsets 0,0,0
#leveling-strategy.rectangular-grid.save false
#leveling-strategy.rectangular-grid.initial_height 10
##leveling-strategy.rectangular-grid.before_probe_gcode M280
##leveling-strategy.rectangular-grid.after_probe_gcode M281
# Levelling strategy
# Example for 3-point levelling strategy, see wiki documentation for other strategies
leveling-strategy.three-point-leveling.enable true # a leveling strategy that probes three points to define a plane and keeps the Z parallel to that plane
leveling-strategy.three-point-leveling.point1 100.0,0.0 # the first probe point (x,y) optional may be defined with M557
leveling-strategy.three-point-leveling.point2 200.0,200.0 # the second probe point (x,y)
leveling-strategy.three-point-leveling.point3 0.0,200.0 # the third probe point (x,y)
leveling-strategy.three-point-leveling.home_first true # home the XY axis before probing
leveling-strategy.three-point-leveling.tolerance 0.03 # the probe tolerance in mm, anything less that this will be ignored, default is 0.03mm
leveling-strategy.three-point-leveling.probe_offsets 0,0,0 # the probe offsets from nozzle, must be x,y,z, default is no offset
leveling-strategy.three-point-leveling.save_plane false # set to true to allow the bed plane to be saved with M500 default is false
leveling-strategy.three-point-leveling.home_first true # home the XY axis before probing
Can you help ? i don't understand what append, commenting the strategy and config work fine.
