which gives me X= 95 and Y = 84, But instead, by Z axis is homing on . Auto Homing showing failing Z-homing. May 2016. Uncomment Z_SAFE_HOMING. Z_SAFE_HOMING. ... Do we have a setting like zprobe.homing_position Xpos,Ypos? // To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN. * * The issue: If a thermistor falls out, it will report the much lower ... #define Z_SAFE_HOMING_X_POINT ((X_BED_SIZE) / 2) // X point for Z homing when homing all axes (G28). G29 - Probe the points The defines for the PROBE_BED_POSITION are the locations where your probes will actually fall. Cihan. BLTouch for ABL Bilinear. G28 - It will home on X and Y then go to the middle of the bed to home the Z. 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. • Click line 97 and hit enter twice, now paste this into line 98: #define AUTO_BED_LEVELING_BILINEAR #define BLTOUCH #define SERVO0_PIN 29 #define Z_SAFE_HOMING A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. Smoothie home X and Y perfectly, and start homing Z at Xmin,Ymax point. FYI for the OP: G0 is a rapid move, G1 is a feed move and you can program them with different rates, but a lot of 3D printers seem to treat them the same. This article describes another release for Marlin this version is 2.0.7.2 based on the release from 22nd October 2020 for use with the Ender 3 Pro and a custom hardware configuration: BigTreeTech SKR 1.4 board, TMC2209 drivers, BLTouch v3.1 (others supported check wiring). X offset – 26; Y offset – 0; Z offset – Calibrate yourself (Set to -1) Baby stepping – enabled; ABL set to #define AUTO_BED_LEVELING_LINEAR for flat bed surfaces; Grid-points set to X=3 Y=X; Z Safe Homing Enabled; LCD Controller. define Z_SAFE_HOMING. // - Prevent Z homing when the Z probe is outside bed area. • Make sure line 96 is commented out. // 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. I know this is the same title as #12726, however I rather started a new issue for clarity as I made quite a few tests. It is also hard to decide if this is a [BUG] or [FR] for Marlin, however it is certainly [BUG] for me. Not sure if this is due to SAFE_HOMING option or something that was enabled. #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). Menu for levelling bed corners. however, when I home the printer, the z axis seems to bind, and the z motors move out of sync. 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. This means that the z axis is homed after both x and y axis are done on the center of the bed. // To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing. This becomes useful when you replace your z axis end switch by sensor. // // With this feature enabled: // // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. When we finish the mounting and cable connections now we will alter some settings in Marlin configuration.h file. Disable Z stallGuard by default; Allow CASE_LIGHT_PIN override from config; Sanity check 3-point defines; Sanity-check Chamber thermistor pin; Add thermistor 502 for Zonestar Prusa P802M; Use center XY for Z Safe Homing default; Independent X2,Y2,Z2,Z3,Z4 endstop inverting; New Machines and Boards.
