When you open the Material Setup form using the Setup Material and Rapid Gaps tool in the Toolpath Tab, you will see settings for Clearance (Z1) and Plunge (Z2).These are also referred to as the Safe Z settings. Successfully merging a pull request may close this issue. I have a modified bed on my printer that is not in line with the X and Y endstops, so I need to be able to tell it to move to a specific spot to home Z. 10 comments Closed ... // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The safe X & Y point automatically get set to the middle of the bed. Usage M121 . // Example: To park the head outside the bed area when homing with G28. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING.

[safe_z_home] home_xy_position: 175.5,253 z_hop: 5.0 Quad Gantry Levelling Settings Without this option enabled the nozzle will crash into the bed when homing. By clicking “Sign up for GitHub”, you agree to our terms of service and // // To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN. Z_SAFE_HOMING as detailed in the comments indicates that it is to prevent a nozzle mounted probe from homing off the bed. We’ll occasionally send you account related emails. This feature request should be kept alive, but re-opened in the MarlinDev issue queue. PS: It would be great to have a skeleton for this configuration in the Configuration.h file. #define Z_probe_mech_endstop //leave enabled unless you have a special type of endstop, #If Enabled(Z_probe_Prox) You signed in with another tab or window. //=========================================================================== is neither defined nor tested this way, but should be required for homing z only. If you're very attached to 1.0.2-1 then perhaps someone can locate the place where the bug was patched and you can apply it to your own copy. So I'm curious. Here is some related settings: I made the if statement unique so that it would not fire twice if auto bed leveling was on instead of mesh bed leveling. Notes. So, I would eliminate all of the #if/#endif from the Configuration section. //=========================== Manual Bed Leveling =========================== After this command endstops will be kept disabled when not homing. @Nanox z home xy is only used for homing order z up xy preheat z. Would these be the release candidates listed as "Not for production use – use with caution!"? Have a question about this project? If homing is needed the LCD will blink the X Y Z indicators. DEFAULT_STEPPER_DEACTIVE_TIME is also set to its default. I'm not joking. But the history of the Safe Homing was because the probe offset from the nozzle was causing problems. @thinkyhead I left most things things at their defaults. I concur with @Blue-Marlin. // // For a servo-based Z probe, you must set up servo support below, including They can be used for homing … As a side-effect, X and Y homing are required before Z homing. I haven't looked at the code real carefully to verify that. Trial and error is the tactic to go. #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. The difference compared to Configuration.h is that it offers us more detailed customization options, and experimental or in development functions. Secondly disable the Z_MIN_PROBE_PIN option as below. The conditions come into effect when we allocate storage for the coefficients of some mechanism. //#define Z_probe_Prox //enable if you have a prox sensor on Z Description. It's fixed now. , //=========================================================================== ), and DEFAULT_STEPPER_DEACTIVE_TIME? < all mech_endstop settings go here> This prevents your Z homing from occuring without prior X and Y homing. // With this feature enabled: // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. // Example: To park the head outside the bed area when homing with G28. #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. //#define Z_probe_Servo //enable if you have a servo sensor on Z This may have side-effects if using SD_ABORT_ON_ENDSTOP_HIT. You would do this by going into Configuration.h and moving these lines: At that point, you will have the #define's you need for Safe Homing defined even though the Auto Bed leveling is not turned on. I realized something else when disabling BLTOUCH. Which means a G28 Z will result in all three axes being homed instead of just Z. // // For a servo-based Z … I would rather use mesh bed leveling, but there appears to be no way to manually set the XY position for Z homing in that mode. Un-comment the proper line in the configuration file to read: #define Z_SAFE_HOMING This will make the printer aware of the sensor, and home Z in the middle of the bed (default behavior, but can be changed), so that your sensor is never off the bed when probing the bed for Z homing. privacy statement. Z Safe Homing prevents Z from homing when the probe (or nozzle) is outside bed area by moving to a defined XY point (by default, the middle of the bed) before Z Homing when homing all axes with G28. Brought to you with lack of and lots of . Because, the new extruder is stopping slightly off the y-axis when homing. #endif Reply to this email directly or view it on GitHub #2877 (comment). ), DISABLE_INACTIVE_X (etc. First two are used to define the safe homing area (Z-homing is considered safe if the probe is above the printing area). If you use false on the Z axis you don’t need to have a switch attached and the machine will think it is home where ever it is when it is homing. #If Enabled(Z_probe_mech_endstop) For example, Will both lead to the unhelpful "Home X/Y before Z" error. M121. The result of homing the z-axis should thus place the build surface at the z=0 plane. 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}).I have the feeling the distance is multiplied by 2 for some reason. This is a bug apparently in 1.0.2-1. So we should work on this in the dev branch for 1.2 and perhaps it can also get into 1.1.1. If using a Probe for Z Homing, enable Z_SAFE_HOMING also! This prevents your Z homing from occurring without prior X and Y homing. 1.0.2-1 is stable in the sense of - No error has been fixed since 18 month. I couldnt solve that leveling command issue. Until then, they are just defining preprocessor names. But things would be less cluttered and not buried in obfuscating nested conditionsl blocks. //===========================================================================, //Can use any sensor type The text was updated successfully, but these errors were encountered: That behaviour does look as if you are not using a recent RC or RCBugFix. privacy statement. @thinkyhead Tried it. I can't find DISABLE_INACTIVE_X in Configuration.h or Configuration_adv.h so its safe to say its set to whatever it's default is. What are your configured settings for DISABLE_X (etc. If i change gamma_min_endstop to Not Connected, i cannot home Z normally. Is there a specific reason that the firmware will not compile if z safe homing is enabled outside the auto bed leveling section, and could it be made to operate independently of any specific bed leveling feature? And Marlin 1.0.x is not being patched at this time. to your account, So this one took me a while to figure out, but basically, having an axis set to disable when "inactive" will lead to issues with z home. G32 uses the probe points defined in eeprom. Z_PROBE_BED_DISTANCE would be fine and for z max homing we even use this for a starting height after z homing … Change DEFAULT_STEPPER_DEACTIVE_TIME to 300 for a better experience. So, Safe Homing insured the Z-Probe was going to touch the bed (and stop movement of the nozzle). #define Z_SAFE_HOMING_Y_POINT ((Y_BED_SIZE) / 2) // Y point for Z homing when homing all axes (G28). make Z safe homing independent of auto bed leveling. Without this, you may accidentally miss the bed when homing Z. // // To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN. Yes i can do that but, when i leveling (G32) with gama min homing active, its make autohome all axis. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Already on GitHub? ... Z_SAFE_HOMING. // To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING. // // For a servo-based Z probe, you must set up servo support below, including It probably would be better stated as a carriage mounted probe. #If Enabled(Z_probe_Servo) Disable endstops. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. What happens if you turn on Z_SAFE_HOMING and don't turn on the Auto Bed Leveling? Now all I have to do is test it out. Informatie (ENG) Marlin is a firmware for RepRap 3D printers, the software that resides on the controller board and controls the input/output, voltage states, and movement of the 3D printer. // Example: To park the head outside the bed area when homing with G28. eg. #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. Homing is required before G29, M48, and some other procedures.. Had zero effect on the stated issue. — // In order to use this, you must have a Z_PROBE_PIN defined in the pins.h file for your control board. Website. Ender3 Pro Octopi Marlin [2.0.5.4] SKR1.4 turbo w/220 … Notes. Please Help going nuts! Z switch should be for safety, because inudctive sensors are not reliable, I have changed 5 inductive sensors because they crashed nozzle into my heatbed. @Blisk — One thing we did add is an option to stop the downward probe movement as soon as it goes past the expected trigger point, so it won't try to go 100mm below the bed… The option is called Z_PROBE_LOW_POINT. Disable endstops. //Must use either servo or proximity sensor #endif Now we will save the Configuration.h file and edit a new file called Configuration_adv.h . To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to … It is going out of the standard 20x20 cm bed. Thanks for the software, I'd be very unhappy without it. To enable safe z homing disable homing override and provide a X,Y coordinate of your Z endstop pin. There was an error in 1.0.2-1. The other X and Z axes are OK. They are all ignored when the printer is homing. This issue has been automatically locked since there has not been any recent activity after it was closed. The only additional definitions required for safe homing in 1.1.0 RC3 are X_PROBE_OFFSET_FROM_EXTRUDER, Y_PROBE_OFFSET_FROM_EXTRUDER, Z_RAISE_BEFORE_HOMING, XY_TRAVEL_SPEED.
