Part 3 – Marlin Configuration Setup. // - Prevent Z homing when the Z probe is outside bed area. (like marlin Z Safe Homing) King Regards. Marlin always includes safe min and max temperature ranges which * protect against a broken or disconnected thermistor wire. // Sets direction of endstops when homing; 1=MAX, -1=MIN #define X_HOME_DIR -1 #define Y_HOME_DIR -1 #define Z_HOME_DIR 1. Removed Safe Homing ( printer no longer homes Z in the middle of the bed, I can't see this being beneficial if you are not using a probe.) // To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN. #define Z_SAFE_HOMING. If compare to the latest (v1.1.9) Configuration.h file from GitHub, here are the changes: 0. Also your z probe xy offset is 0 whcih is only the case if it is the extruder nozzle.

Configuring Endstops on Ramps 1.4 With Marlin Firmware - @section Homing : This is going to be a, hopefully, complete tutorial on configuring endstops on 3D printers build on Ramps 1.4 using Marlin firmware.I am going to use Pronterface/Printrun host program to connect to my printer and issue terminal commands (G-codes). I’m using dual endstops on the X and Y axis, and no endstop on the Z axis. Right now, G28 first lifts Z by 10mm, homes X and Y, and then tries to home Z, but since there is no endstop it would push the spindle into the wasteboard and probably rip itself apart. // - Prevent Z homing when the Z probe is outside bed area. Does Marlin use the hot end tip or the tip of the Z probe as reference when leveling itself? If not make sure offset relative to extruder is set correctly. Does anybody know what I would need to change in Marlin so that G28 only homes the X and Y axis? Smoothie home X and Y perfectly, and start homing Z at Xmin,Ymax point.

Then it moves to home X, and it tries to move the Z-axis up to Z_HOMING_HEIGHT, which is set from Z_CLEARANCE_BETWEEN_PROBES if that is defined (which it was for me, and it was 5). You might want to set homing order to xy Temp. #if ENABLED(Z_SAFE_HOMING) #define Z_SAFE_HOMING_X_POINT ((X_BED_SIZE) / 2) // X point for Z homing when homing all axes (G28). Without this, you may accidentally miss the bed when homing Z.

This prevents your Z homing from occuring without prior X and Y homing. Without this option enabled the nozzle will crash into the bed when homing. Marlin 2.0.5.3; Filament Runout (Connect to E0DET pins) Square Wave Stepping (Beta Feature) * Create a 50/50 square wave step pulse optimal for stepper drivers. Uncomment and set #define MANUAL_Z_HOME_POS -0.15; Uncomment #define Z_SAFE_HOMING. This becomes useful when you replace your z axis end switch by sensor. Default for this setting puts the nozzle in the center of the bed for G28Z, but you can define a corner offset if you wish. Marlin v2.0.6 – Posted 28th July 2020; Key Features. Intro. It is common for X and Y axis to home the hot end to the Zero location and Z axis end stop home to the maximum positive location.
