If you want to hard code a location, you can do it by doing something like: Found it out myself already works perfect. It will not smash down into your spoil board. 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. Tricky, as there have been ~800 patches since 1.0.2-1. I don't know that it will work, but it has a fair chance of working. @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. If stepper drivers time out, X and Y homing will be required again. If using a Probe for Z Homing, enable Z_SAFE_HOMING also! We’ll occasionally send you account related emails. privacy statement. So if you are not running G28 it is ignored. 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. Disable endstops. 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. G28 disables bed leveling. 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. There was an error in 1.0.2-1. Please give that a try and let us know what happened. Thanks for the software, I'd be very unhappy without it. As a side-effect, X and Y homing are required before Z homing. Which means a G28 Z will result in all three axes being homed instead of just Z. Does not work, still attempts to home Z at X=0, and Y=0. So search and enable Z_SAFE_HOMING if using a BlTouch or probe. Ender3 Pro Octopi Marlin [2.0.5.4] SKR1.4 turbo w/220 … ... Z_SAFE_HOMING. 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. //===========================================================================, //Can use any sensor type So, Safe Homing insured the Z-Probe was going to touch the bed (and stop movement of the nozzle). I couldnt solve that leveling command issue. Have a question about this project? , //=========================================================================== This is a bug apparently in 1.0.2-1. #If Enabled(Z_probe_Servo) Right now, in order to do that, I would have to enable auto-bed leveling, which is incompatible with my printbed. But things would be less cluttered and not buried in obfuscating nested conditionsl blocks. But the history of the Safe Homing was because the probe offset from the nozzle was causing problems. The result of homing the z-axis should thus place the build surface at the z=0 plane. // // For a servo-based Z probe, you must set up servo support below, including If you don’t want that then you … 1.0.2-1 is stable in the sense of - No error has been fixed since 18 month. #endif //it is highly recommended you let this Z_SAFE_HOMING enabled!!! They can be used for homing … By clicking “Sign up for GitHub”, you agree to our terms of service and #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. I don't consider the time it takes to move from one instruction to the next as inactivity. This issue has been automatically locked since there has not been any recent activity after it was closed. Z_SAFE_HOMING as a general option is something that we have discussed a lot and everyone agrees it can be helpful. [safe_z_home] home_xy_position: 175.5,253 z_hop: 5.0 Quad Gantry Levelling Settings 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. < all servo settings go here(sled options, other servo stuff)> It is going out of the standard 20x20 cm bed. Without this, you may accidentally miss the bed when homing Z. Trial and error is the tactic to go. If homing is needed the LCD will blink the X Y Z indicators. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to … Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Have a question about this project? Change DEFAULT_STEPPER_DEACTIVE_TIME to 300 for a better experience. #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. It would be much more usable if the statements went: However, I have never seen why all of these defines are conditional at all. // // To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN. //#define Z_probe_Servo //enable if you have a servo sensor on Z If i change gamma_min_endstop to Not Connected, i cannot home Z normally. #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. // In order to use this, you must have a Z_PROBE_PIN defined in the pins.h file for your control board. Z_SAFE_HOMING_X_POINT and Z_SAFE_HOMING_Y_POINT are used only when you home all axes with G28 command. PS: It would be great to have a skeleton for this configuration in the … If you homed the Z-Axis in a location where the Z-Probe would miss the bed, really bad things happened. i tried looking at marlin.main, as that's where it was throwing errors before, but i dont really see the issue, although it does say this: Ok, after looking at it a bit more, it might be better if there was just had a section for the type of z axis sensor used, with all the options for that sensor being in that section, If I'm using a prox sensor and I don't want to use auto bed leveling, I cant access the option to use an alternate z min probe pin either. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. It will move up a little twice when it is homing Z. // Only one of these can be on at a time. DEFAULT_STEPPER_DEACTIVE_TIME is also set to its default. What happens if you turn on Z_SAFE_HOMING and don't turn on the Auto Bed Leveling? Without this, you may accidentally miss the bed when homing Z. < all mech_endstop settings go here> // You will want to disable Z_SAFE_HOMING above as you will still use the Z min endstop for homing. Until then, they are just defining preprocessor names. It probably would be better stated as a carriage mounted probe. // With this feature enabled: // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. // // To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN. #define Z_SAFE_HOMING • Uncomment line 110. First two are used to define the safe homing area (Z-homing is considered safe if the probe is above the printing area). ), DISABLE_INACTIVE_X (etc. If the measurements check out as above, then it should be safe to send the Z axis to zero position, send the g-code command G1 Z0 through the terminal. // To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING. And Marlin 1.0.x is not being patched at this time. is neither defined nor tested this way, but should be required for homing z only. So, I have played with the #defines explained below, but I couldn't even make any single mm difference by homing. Sign in Thanks tho for the quick answer. Reply to this email directly or view it on GitHub #2877 (comment). I concur with @Blue-Marlin. 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. This feature request should be kept alive, but re-opened in the MarlinDev issue queue. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. I think it is because of the Z_Safe_Homing … 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_Prox //enable if you have a prox sensor on Z Uncomment Z_SAFE_HOMING. Secondly disable the Z_MIN_PROBE_PIN option as below. Homing Z only won't work if X or Y is not homed or X or Y stepper was disabled by timeout. Mechanica Firmware – Marlin. @thinkyhead I left most things things at their defaults. This prevents your Z homing from occurring without prior X and Y homing. You signed in with another tab or window. Please open a new issue for related bugs. Actual behaviour: Z_Safe_Homing home in the back right corner; When I print a calibration cube with cura (I made the configuration of the bed dimension in cura), even if the cube is place in the middle of the plate, the cube print in the back right corner. Clearance (Z1) and Plunge (Z2) The Clearance (Z1) is the most important setting. If you're not using Marlin or newer versions of Marlin, then you should ignore this :) 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? // Example: To park the head outside the bed area when homing with G28. < all prox settings go here (including alt z min probe, Z_safe homing, etc)> 10 comments Closed ... // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. to your account. eg. We’ll occasionally send you account related emails. They are all ignored when the printer is homing. Examples. Z_SAFE_HOMING_X_POINT and Z_SAFE_HOMING_Y_POINT are used only when you home all axes with G28 command. P.S. //it is highly recommended you let this Z_SAFE_HOMING enabled!!! This may have side-effects if using SD_ABORT_ON_ENDSTOP_HIT. Notes. @Nocturnal42 Neither do we. // Example: To park the head outside the bed area when homing with G28. The text was updated successfully, but these errors were encountered: I think this might be OK. Z_PROBE_BED_DISTANCE would be fine and for z max homing we even use this for a starting height after z homing … 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. 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. //Must use either servo or proximity sensor I'm not joking. #If Enabled(Z_probe_mech_endstop) 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. I haven't looked at the code real carefully to verify that. // Use “Z Safe Homing” to avoid homing with a Z probe outside the bed area. 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. I realized something else when disabling BLTOUCH. Successfully merging a pull request may close this issue. The other X and Z axes are OK. So, I would eliminate all of the #if/#endif from the Configuration section. 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). 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. Uncomment Z_SAFE_HOMING. So we should work on this in the dev branch for 1.2 and perhaps it can also get into 1.1.1. Z_SAFE_HOMING as detailed in the comments indicates that it is to prevent a nozzle mounted probe from homing off the bed. Yes i can do that but, when i leveling (G32) with gama min homing active, its make autohome all axis. Description. Would these be the release candidates listed as "Not for production use – use with caution!"? Because, the new extruder is stopping slightly off the y-axis when homing. I hope they will enable this in marlin. //===========================================================================. After this command endstops will be kept disabled when not homing. //=========================================================================== // // For a servo-based Z probe, you must set up servo support below, including //==============================Z Endstop Options =========================== Website. 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. make Z safe homing independent of auto bed leveling. // To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING. *_PROBE_BED_POSITION are used for auto-leveling only. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to (40*60) and HOMING_FEEDRATE_Z from (4*60) to (8*60). I made the if statement unique so that it would not fire twice if auto bed leveling was on instead of mesh bed leveling. A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. 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. Already on GitHub? Sign in — This prevents your Z homing from occuring without prior X and Y homing. #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. To enable safe z homing disable homing override and provide a X,Y coordinate of your Z endstop pin. So I'm curious. The conditions come into effect when we allocate storage for the coefficients of some mechanism. Here is some related settings: Already on GitHub? Successfully merging a pull request may close this issue. Now all I have to do is test it out. Like I say, I haven't looked at the code real carefully to verify this, but this does seem like a reasonable request.

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. What are your configured settings for DISABLE_X (etc. Homing is required before G29, M48, and some other procedures.. Plus this comment, // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. By clicking “Sign up for GitHub”, you agree to our terms of service and You signed in with another tab or window. 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. 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.

The difference compared to Configuration.h is that it offers us more detailed customization options, and experimental or in development functions. For example, Will both lead to the unhelpful "Home X/Y before Z" error. 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). // To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING. @Nanox z home xy is only used for homing order z up xy preheat z. #define Z_SAFE_HOMING_Y_POINT ((Y_BED_SIZE) / 2) // Y point for Z homing when homing all axes (G28). • Go to line 380 and set Y offset to mount offset (Recommended mounts use -10 for the Y offset.) The safe X & Y point automatically get set to the middle of the bed. #endif Usage M121 . Yes. 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. Had zero effect on the stated issue.
