* To use a custom Z Probe pin, set Z_MIN_PROBE_PIN below. And your Z-Safe homing config look like this. Without this option enabled the nozzle will crash into the bed when homing. • Go to line 402 and set Y offset to mount offset (Recommended mounts use -10 for the Y offset.) marlin creality-ender-3 homing. It seems to be driving ok apart from the steps per unit seem to be out. //# define MIN_SOFTWARE_ENDSTOP_Z… In Marlin 1.x, this was done with X, Y, and Z_PROBE_OFFSET_FROM_EXTRUDER. BLTouch v3.1 (other versions of the BLTouch will work but you will need to adjust settings related to it and check your wiring). define Z_MIN_PROBE_ENDSTOP_INVERTING false define BLTOUCH define SERVO0_PIN 27 define NOZZLE_TO_PROBE_OFFSET { -25, -38, 2 } define AUTO_BED_LEVELING_BILINEAR define Z_SAFE_HOMING //#define SDSUPPORT. I can not get this thing to home the z-axis properly, much less complete G29 for autobed leveling. Now the printer seems to be of two minds when it comes to finding the origin. Bed size: 235 x 235 Nozzle is at front left corner of bed at (5,5) // The size of the print bed. The current position is adjusted to align to the new home offset values. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. 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.

Undoubtedly without the EEPROM option being enabled, many of the Marlin … But it then goes to the center of the bed. For the whole day I am trying to configure Marlin bugfix-2.0.x to achieve seemingly very simple things: Always monitor endstop switches when moving. 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. If compare to the latest (v1.1.9) Configuration.h file from GitHub, here are the changes: * Enable this option for a probe connected to any pin except Z-Min. dual z marlin 2.0 SKR tronxy x5s. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. #define Z_SAFE_HOMING. #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). Ender 3 Pro or 3. It’s assumed that you have the following equipment: BTT SKR 1.4 Board. README.md: 2020-07-27: 12.6 kB: 0. i.e. Marlin 2.0.4.tar.gz: 2020-02-21: 4.1 MB: 0. #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.) 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. Without a doubt a particularly critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. Marlin [2.0.5.4 Z_Safe_Homing not centered, Bltouch going off bed. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. I installed a BLTouch bed leveling probe on my printer which uses Marlin 2.0.5.3. This build is a suppose to be a dedicated, large format 3D printer. 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. @section extras . I have a Robo R1+ which uses the nozzle contacting the glass print bed to level the printer. 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}). When I do a G28 to test the print head goes as expected to the front left of the print bed. 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.) I have the feeling the distance is multiplied by 2 for some reason. // - Prevent Z homing when the Z probe is outside bed area. Without this option enabled the nozzle will crash into the bed when homing. Marlin 2.0.4.4 has been edited for the BL Touch with changes below but whole file is attached. So search and enable Z_SAFE_HOMING if using a BlTouch or probe. Every time a setting is changed on a 3D printer the information can be lost if it is not saved. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. Totals: 3 Items : 9.6 MB: 3: New Features . Features Highlight . @section extras. Setting up Marlin 2.x.x on my first time CoreXY Hypercube build and where do you establish "home" in configuration.h . // - Move the Z probe (or nozzle) to a defined XY point before Z Homing. It’s safer to leave Z as 0 here are calibrate this yourself later. #define Z_SAFE_HOMING. So search and enable Z_SAFE_HOMING. In Marlin 1.x, this was done with X, Y and Z_PROBE_OFFSET_FROM_EXTRUDER. Z Safe homing; Advanced pause and filament change; It’s assumed that you have the following equipment: BTT SKR 1.4 Board. Here is what I have in Marlin 2.0 – I’ve tried everything, so please let me know what doesn’t look right. Undoubtedly without the EEPROM option being enabled, many of the Marlin options will be lost once … If you have a capacitive sensor, electro-mechanical, or just mechanical sensor for Z, you can search for that in "Configuration.h", uncomment to enable it and then upload the firmware to the board. README.md: 2020-02-21: 2.9 kB: 0. * * If using a Probe for Z Homing, enable Z_SAFE_HOMING also! The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. Last Bed Leveling results Recv: echo: G29 W I0 J0 Z-0.09000 … I recently upgraded from an Arduino to an SKR 1.3 running Marlin 2.0 and have been trying to make the printer auto level. Z Safe homing; Advanced pause and filament change; Classic Jerk or Junction Deviation (see note below) Read more on changes/fixes in the official Marlin 2.0.7.2 change log and Marlin 2.0.7.1 change log. This will let you adjust the Z to a negative number for your offset. I want the print head to end up at the front left and that spot being 0,0,0. For 3 days I have been trying to get my MPCNC build working using Marlin + RAMPS 1.4 and now I am about ready to light this thing on fire and push it into the driveway. See examples below. It’s safer to leave Z as 0 here are calibrate this yourself later. So search and enable Z_SAFE_HOMING if using a BlTouch or probe. 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. 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. You will need to make sure software endstops are DISABLED for Z after adding the probe. Without a doubt a particularly critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. Importantly if you using a BlTouch or probe, search for and enable Z_SAFE_HOMING. Marlin 2.0.6.zip: 2020-07-27: 6.0 MB: 5. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. * (By default Marlin assumes the Z-Max endstop pin.) Instructions are in the comments. 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. I'm not sure what firmware this board runs, but Marlin has the capability to do a "Z_SAFE_HOMING". Please Login to Comment Gnattycole . Today I flashed my Anet ET5 with the Marlin 2.0.X Bugfix Branch, following the Tutorial DrVax made (great Tutorial ,I am probably just stupid). #define Z_SAFE_HOMING @section extras. //-//#define Z_SAFE_HOMING + #define Z_SAFE_HOMING: #if ENABLED(Z_SAFE_HOMING) #define Z_SAFE_HOMING_X_POINT X_CENTER // X point for Z homing @@ -1399,7 +1400,7 @@ #endif // Homing speeds (mm/m) Instructions are in the comments. Ender 3 or 3 Pro; Preparation. When the print head strikes the bed the Z-min endstops open signaling that the bed is touched. x and y vibrate when moving to the z safe homing point by macalikm: 112 2: 12/02/2020 04:02PM Last Post by macalikm: endstops always on per endstop?
