Z_SAFE_HOMING_X_POINT and Z_SAFE_HOMING_Y_POINT are used only when you home all axes with G28 command. The safe X & Y point automatically get set to the middle of the bed. 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_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. Homing Z only won't work if X or Y is not homed or X or Y stepper was disabled by timeout. As a side-effect, X and Y homing are required before Z homing. Notes. 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. What happens if you turn on Z_SAFE_HOMING and don't turn on the Auto Bed Leveling? Already on GitHub? 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. make Z safe homing independent of auto bed leveling. 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. I think it is because of the Z_Safe_Homing … I don't consider the time it takes to move from one instruction to the next as inactivity. This may have side-effects if using SD_ABORT_ON_ENDSTOP_HIT.

Would these be the release candidates listed as "Not for production use – use with caution!"? Tricky, as there have been ~800 patches since 1.0.2-1. @Nanox z home xy is only used for homing order z up xy preheat z. If stepper drivers time out, X and Y homing will be required again. Already on GitHub? It is therefore recommended you update to 1.1.0-RC7 or start tracking along with RCBugFix. #endif By clicking “Sign up for GitHub”, you agree to our terms of service and 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. Personally, I don't consider the time it takes to move from one instruction to the next as inactivity, but there it is. Yes i can do that but, when i leveling (G32) with gama min homing active, its make autohome all axis. If homing is needed the LCD will blink the X Y Z indicators. Where do I enter my values here? 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). But the history of the Safe Homing was because the probe offset from the nozzle was causing problems. It's fixed now. , //=========================================================================== Like I say, I haven't looked at the code real carefully to verify this, but this does seem like a reasonable request. It probably would be better stated as a carriage mounted probe. #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. But things would be less cluttered and not buried in obfuscating nested conditionsl blocks. DEFAULT_STEPPER_DEACTIVE_TIME is also set to its default. Please give that a try and let us know what happened. This prevents your Z homing from occuring without prior X and Y homing.

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. #endif Now we will save the Configuration.h file and edit a new file called Configuration_adv.h . //#define Z_probe_Prox //enable if you have a prox sensor on Z To enable safe z homing disable homing override and provide a X,Y coordinate of your Z endstop pin. Without this, you may accidentally miss the bed when homing Z. If you don’t want that then you … Description. Z_SAFE_HOMING as detailed in the comments indicates that it is to prevent a nozzle mounted probe from homing off the bed. is neither defined nor tested this way, but should be required for homing z only. I don't know that it will work, but it has a fair chance of working. // Example: To park the head outside the bed area when homing with G28. It will move up a little twice when it is homing Z. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to … Z_SAFE_HOMING_X_POINT and Z_SAFE_HOMING_Y_POINT are used only when you home all axes with G28 command. 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. Clearance (Z1) and Plunge (Z2) The Clearance (Z1) is the most important setting. — Examples. I haven't looked at the code real carefully to verify that. Notes. Without this option enabled the nozzle will crash into the bed when homing. //===========================================================================. Right now, in order to do that, I would have to enable auto-bed leveling, which is incompatible with my printbed. I couldnt solve that leveling command issue. P.S. < all servo settings go here(sled options, other servo stuff)> Website. The difference compared to Configuration.h is that it offers us more detailed customization options, and experimental or in development functions. //===========================================================================, //Can use any sensor type 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. // Use “Z Safe Homing” to avoid homing with a Z probe outside the bed area. If using a Probe for Z Homing, enable Z_SAFE_HOMING also! // To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING. // // For a servo-based Z … 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? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. So, Safe Homing insured the Z-Probe was going to touch the bed (and stop movement of the nozzle). //=========================================================================== 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. 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. What are your configured settings for DISABLE_X (etc. 10 comments Closed ... // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Which means a G28 Z will result in all three axes being homed instead of just Z. #define Z_SAFE_HOMING_Y_POINT ((Y_BED_SIZE) / 2) // Y point for Z homing when homing all axes (G28). Because, the new extruder is stopping slightly off the y-axis when homing. Z_SAFE_HOMING as a general option is something that we have discussed a lot and everyone agrees it can be helpful. 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. Please open a new issue for related bugs. Plus this comment, // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. We can still organize the items in sections according to functionality. 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. // You will want to disable Z_SAFE_HOMING above as you will still use the Z min endstop for homing. I concur with @Blue-Marlin. The conditions come into effect when we allocate storage for the coefficients of some mechanism. They can be used for 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. I hope they will enable this in marlin. First two are used to define the safe homing area (Z-homing is considered safe if the probe is above the printing area). //=========================== Manual Bed Leveling =========================== @thinkyhead I left most things things at their defaults. to your account. The other X and Z axes are OK. 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. So, I would eliminate all of the #if/#endif from the Configuration section. Without this, you may accidentally miss the bed when homing Z. You signed in with another tab or window.
