In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. BLTouch v3.1 (other versions of the BLTouch will work but you will need to adjust settings related to it and check your wiring). From the configuration.h file for Marlin firmware you can find the following options: /** * Choose one of the options below to enable G29 Bed Leveling. Use center XY for Z Safe Homing default; Independent X2,Y2,Z2,Z3,Z4 endstop inverting; Add a custom nozzle wipe G-code option; Board / HAL. @section extras . In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. I left Z_SAFE_HOMING enabled and instead of going at the middle of the bed, it goes at the top end right corner ({30,30} instead of {15,15}). Creality offers the firmware on their website as a .hex file - which is hard to edit. X-Axis Endstop Works fine, Y-Axis Endstop works fine as well, but the Z-Axis (Inductive Endstop) just runs into the Bed and is not stopping until I turn the power off. Z Safe homing; Advanced pause and filament change; Classic Jerk; Read more on changes in the official Marlin 2.0.6 change log. #define Z_SAFE_HOMING @section extras. Z_SAFE_HOMING. I have the feeling the distance is multiplied by 2 for some reason. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. After the final adjusted firmware upload, and bringing the sensor up, I see that the extruder pushes the bed down a bit when I auto home and then the LCD screen says probing failed. In Marlin 1.x, this was done with X, Y and Z_PROBE_OFFSET_FROM_EXTRUDER. The idea of Z safe homing is that it is forced to home Z in the middle of the bed (bed size/2) so the inductive probe does not try to trigger in thin air. 0scar ♦ 24.8k 6 6 gold badges 38 38 silver badges 103 103 bronze badges. It’s safer to leave Z as 0 here are calibrate this yourself later. So search and enable Z_SAFE_HOMING.

Instructions are in the comments. #define Z_SAFE_HOMING @section extras. I'm not sure what firmware this board runs, but Marlin has the capability to do a "Z_SAFE_HOMING". Setting up Marlin 2.x.x on my first time CoreXY Hypercube build and where do you establish "home" in configuration.h . Add 2 // in front of the MIN_SOFTWARE_ENDSTOP_Z line in your Configuration.h file as shown below. Not sure if anyone has successfully cracked this but I'm trying to set up a dual Z drive using the E1 port as a Z2 stepper driver. So search and enable Z_SAFE_HOMING if using a BlTouch or probe. * * If using a Probe for Z Homing, enable Z_SAFE_HOMING also! This feature is so sensitive that it can actually take the place of traditional endstops. I have a Robo R1+ which uses the nozzle contacting the glass print bed to level the printer. #define Z_SAFE_HOMING. According to Repetier Host it runs on Marlin 1.0. Undoubtedly without the EEPROM option being enabled, many of the Marlin options will be lost once … Now the printer seems to be of two minds when it comes to finding the origin.

Without a doubt a particularly critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). Importantly if you using a BlTouch or probe, search for and enable Z_SAFE_HOMING. • Go to line 402 and set Y offset to mount offset (Recommended mounts use -10 for the Y offset.) BLTouch v3.1 (other versions of the BLTouch will work but you will need to adjust settings related to it and check your wiring). Without this option enabled the nozzle will crash into the bed when homing. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. This build is a suppose to be a dedicated, large format 3D printer. * * - The simplest option is to use a free endstop connector. It seems to be driving ok apart from the steps per unit seem to be out. You will need to make sure software endstops are DISABLED for Z after adding the probe. #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). Thanks for any help. And your Z-Safe homing config look like this. Everything worked really great until I arrived at Autohoming. #define Z_SAFE_HOMING • Uncomment line 110 - #define CUSTOM_PROBE • Go to line 401 and set X offset to mount offset (recommended mounts use -40 for the X offset.) See examples below. Undoubtedly without the EEPROM option being enabled, many of the Marlin … Homing XY moves to the lower left as it always has, but homing Z moves not only to Z=0, but also to the center of the build plate. Instructions are in the comments. This is a no-brainer for every CNC owner which finds it logical for Endstop and E-Stop switches being de-facto limits which unconditionaly stop any CNC movement (unless disabled with M121).
