My machine, a converted Proxxon MF70, has a problem that I’m unable to home the machine. When I turn on the power, and the axis are somewhere in the middle, smoothie says they are at their 0-position. Pressing home in smoothie web does nothing. If I jog an axis some, the home button reverses the axis to the position in which the machine was at power on.
Jogging the machine using smoothie web confirms the steppers work, the axis move in the right direction. The M119 command shows the endpoints work correctly (they are NO). So what am I missing in the configuration?
Pressing home should move all three axis until they hit their designated endpoints and then stay there or move to the configured origin point right?
The info:
Hardware: smoothieboard v1.0

Configuration of the endstops:
@<
[[code]]
endstops_enable true # The endstop module is enabled by default and can be disabled here
corexy_homing false # Set to true if homing on a hbot or corexy
alpha_min_endstop 1.24!^ # Pin to read min endstop, add a ! to invert if endstop is NO connected to ground
#alpha_max_endstop 1.25!^ # Pin to read max endstop, uncomment this and comment the above if using max endstops
alpha_homing_direction home_to_min # Or set to home_to_max and set alpha_max and uncomment the alpha_max_endstop
alpha_min 0 # This gets loaded as the current position after homing when home_to_min is set
alpha_max 200 # This gets loaded as the current position after homing when home_to_max is set
beta_min_endstop 1.26!^ # Pin to read min endstop, add a ! to invert if endstop is NO connected to ground
#beta_max_endstop 1.27^ # Pin to read max endstop, uncomment this and comment the above if using max endstops
beta_homing_direction home_to_min # Or set to home_to_max and set alpha_max and uncomment the alpha_max_endstop
beta_min 0 # This gets loaded as the current position after homing when home_to_min is set
beta_max 160 # This gets loaded as the current position after homing when home_to_max is set
gamma_min_endstop 1.28!^ # Pin to read min endstop, add a ! to invert if endstop is NO connected to ground
#gamma_max_endstop 1.29^ # Pin to read max endstop, uncomment this and comment the above if using max endstops
gamma_homing_direction home_to_min # Or set to home_to_max and set alpha_max and uncomment the alpha_max_endstop
gamma_min 0 # This gets loaded as the current position after homing when home_to_min is set
gamma_max 80 # This gets loaded as the current position after homing when home_to_max is set
alpha_max_travel 200 # Max travel in mm for alpha/X axis when homing
beta_max_travel 160 # Max travel in mm for beta/Y axis when homing
gamma_max_travel 80 # Max travel in mm for gamma/Z axis when homing
- Optional enable limit switches, actions will stop if any enabled limit switch is triggered
alpha_limit_enable true # Set to true to enable X min and max limit switches
beta_limit_enable true # Set to true to enable Y min and max limit switches
gamma_limit_enable true # Set to true to enable Z min and max limit switches
- Endstops home at their fast feedrate first, then once the endstop is found they home again at their slow feedrate for accuracy
alpha_fast_homing_rate_mm_s 50 # Alpha/X fast homing feedrate in mm/second
alpha_slow_homing_rate_mm_s 25 # Alpha/X slow homing feedrate in mm/second
beta_fast_homing_rate_mm_s 50 # Beta/Y fast homing feedrate in mm/second
beta_slow_homing_rate_mm_s 25 # Beta/Y slow homing feedrate in mm/second
gamma_fast_homing_rate_mm_s 4 # Gamma/Z fast homing feedrate in mm/second
gamma_slow_homing_rate_mm_s 2 # Gamma/Z slow homing feedrate in mm/second
alpha_homing_retract_mm 5 # Distance to retract from the endstop after it is hit for alpha/X
beta_homing_retract_mm 5 # Distance to retract from the endstop after it is hit for beta/Y
gamma_homing_retract_mm 1 # Distance to retract from the endstop after it is hit for gamma/Z
- Optional order in which axis will home, default is they all home at the same time,
- If this is set it will force each axis to home one at a time in the specified order
#homing_order XYZ # X axis followed by Y then Z last
move_to_origin_after_home true # Move XY to 0,0 after homing
#endstop_debounce_count 100 # Uncomment if you get noise on your endstops, default is 100
#endstop_debounce_ms 1 # Uncomment if you get noise on your endstops, default is 1 millisecond debounce
home_z_first true # Uncomment and set to true to home the Z first, otherwise Z homes after XY
- End of endstop config
