This issue has been automatically locked since there has not been any recent activity after it was closed. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. It's fixed now. If stepper drivers time out, X and Y homing will be required again. The result of homing the z-axis should thus place the build surface at the z=0 plane. We're just a little shy to mess with any homing or leveling code because it deals with a lot of different configurations and it can be kind of fragile. They are all ignored when the printer is homing. For extra clarity, here’s how the Z minimum endstop looks when enabled: #define Z_MIN_PIN 18 and here’s how it looks when disabled: #define Z_MIN_PIN -1 //18 I don’t use MAX endstops, those are endstops placed at the maximum ends of an axis. While helping to enlighten me as to what was going on, did not actually inform of the clash while I was making my configuration choices. //#define Z_probe_Prox //enable if you have a prox sensor on Z ), DISABLE_INACTIVE_X (etc. Would these be the release candidates listed as "Not for production use – use with caution!"? I haven't looked at the code real carefully to verify that. I concur with @Blue-Marlin. //===========================================================================, //Can use any sensor type Without this, you may accidentally miss the bed when homing Z. When the Z axis is at the end stop, the gap between the hot end nozzle and the platform should be slightly more than both Z_MAX_POS and home offset added together. Until then, they are just defining preprocessor names. The following configuration works on 1.1.0 RC3: Safe Z-homing area is defined by X_PROBE_OFFSET_FROM_EXTRUDER and Y_PROBE_OFFSET_FROM_EXTRUDER (homing is allowed if the probe is within the printing area). ok, that didn't work, but it gave me a hint to something that at least compiles. Tricky, as there have been ~800 patches since 1.0.2-1. 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. There was an error in 1.0.2-1. 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. By clicking “Sign up for GitHub”, you agree to our terms of service and They can be used for homing … to your account. But the history of the Safe Homing was because the probe offset from the nozzle was causing problems. 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. //#define Z_probe_Servo //enable if you have a servo sensor on Z , //=========================================================================== • Go to line 380 and set Y offset to mount offset (Recommended mounts use -10 for the Y offset.) 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. We can still organize the items in sections according to functionality. But things would be less cluttered and not buried in obfuscating nested conditionsl blocks. #endif Now we will save the Configuration.h file and edit a new file called Configuration_adv.h . @Nanox z home xy is only used for homing order z up xy preheat z. // With this feature enabled: // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Description. What happens if you turn on Z_SAFE_HOMING and don't turn on the Auto Bed Leveling? So search and enable Z_SAFE_HOMING if using a BlTouch or probe. PS: It would be great to have a skeleton for this configuration in the … // In order to use this, you must have a Z_PROBE_PIN defined in the pins.h file for your control board. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to … // Example: To park the head outside the bed area when homing with G28.

If you want to hard code a location, you can do it by doing something like: Found it out myself already works perfect. Z_SAFE_HOMING_X_POINT and Z_SAFE_HOMING_Y_POINT are used only when you home all axes with G28 command. 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. #If Enabled(Z_probe_mech_endstop) //==============================Z Endstop Options =========================== For example, Will both lead to the unhelpful "Home X/Y before Z" error. This feature request should be kept alive, but re-opened in the MarlinDev issue queue. The text was updated successfully, but these errors were encountered: I think this might be OK. Uncomment Z_SAFE_HOMING. It will not smash down into your spoil board. #define Z_probe_mech_endstop //leave enabled unless you have a special type of endstop, #If Enabled(Z_probe_Prox) M121 - Disable Endstops control Disable endstops and keep them enabled when not homing. // // For a servo-based Z probe, you must set up servo support below, including 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. Yes. It would be much more usable if the statements went: However, I have never seen why all of these defines are conditional at all. 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. < all prox settings go here (including alt z min probe, Z_safe homing, etc)> Here is some related settings: Have a question about this project? On Jan 1, 2016, at 5:32 PM, MacTheApple notifications@github.com wrote: It would be mush more usable if the statements went: //=========================================================================== privacy statement. I couldnt solve that leveling command issue. The safe X & Y point automatically get set to the middle of the bed. Where do I enter my values here? Already on GitHub? #endif The other X and Z axes are OK. // // For a servo-based Z … Homing is required before G29, M48, and some other procedures.. ), and DEFAULT_STEPPER_DEACTIVE_TIME? If homing is needed the LCD will blink the X Y Z indicators. If i change gamma_min_endstop to Not Connected, i cannot home Z normally. Website. If you don’t want that then you … So, I would eliminate all of the #if/#endif from the Configuration section. 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. Now all I have to do is test it out. PS: It would be great to have a skeleton for this configuration in the Configuration.h file. 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. DEFAULT_STEPPER_DEACTIVE_TIME is also set to its default. I think it is because of the Z_Safe_Homing … Homing Z only won't work if X or Y is not homed or X or Y stepper was disabled by timeout. // // To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN. //============================ Bed Auto Leveling ============================ A work around is to disable Z safe homing or to move the safe area to 0,0 instead of bedwith/2,beddepth/2 Another thing you can do is use older versions of Marlin that don't currently have this bug. Does not work, still attempts to home Z at X=0, and Y=0. Please open a new issue for related bugs. You signed in with another tab or window. #define Z_SAFE_HOMING • Uncomment line 110. This prevents your Z homing from occurring without prior X and Y homing. make Z safe homing independent of auto bed leveling.
