disable z safe homing

I couldnt solve that leveling command issue. Now all I have to do is test it out. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to … 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. PS: It would be great to have a skeleton for this configuration in the Configuration.h file. G32 uses the probe points defined in eeprom. Sign in #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. //============================ Bed Auto Leveling ============================ Plus this comment, // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. //Must use either servo or proximity sensor ), DISABLE_INACTIVE_X (etc. Trial and error is the tactic to go. P.S. [safe_z_home] home_xy_position: 175.5,253 z_hop: 5.0 Quad Gantry Levelling Settings eg. Have a question about this project? Brought to you with lack of and lots of . #endif Right now, in order to do that, I would have to enable auto-bed leveling, which is incompatible with my printbed. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. Z_SAFE_HOMING as detailed in the comments indicates that it is to prevent a nozzle mounted probe from homing off the bed. M121. If you're not using Marlin or newer versions of Marlin, then you should ignore this :) The safe X & Y point automatically get set to the middle of the bed. Z_SAFE_HOMING as a general option is something that we have discussed a lot and everyone agrees it can be helpful. Without this option enabled the nozzle will crash into the bed when homing. Please Help going nuts! // You will want to disable Z_SAFE_HOMING above as you will still use the Z min endstop for homing. I don't know that it will work, but it has a fair chance of working. If stepper drivers time out, X and Y homing will be required again. Successfully merging a pull request may close this issue. Marlin [2.0.5.4 Z_Safe_Homing not centered, Bltouch going off bed. privacy statement. After this command endstops will be kept disabled when not homing. 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. I realized something else when disabling BLTOUCH. So, I have played with the #defines explained below, but I couldn't even make any single mm difference by homing. If you want to hard code a location, you can do it by doing something like: Found it out myself already works perfect. // To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING. // Only one of these can be on at a time. // Example: To park the head outside the bed area when homing with G28. A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. 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. Homing is required before G29, M48, and some other procedures.. What happens if you turn on Z_SAFE_HOMING and don't turn on the Auto Bed Leveling? ... Z_SAFE_HOMING. Clearance (Z1) and Plunge (Z2) The Clearance (Z1) is the most important setting. Here is some related settings: We’ll occasionally send you account related emails. //it is highly recommended you let this Z_SAFE_HOMING enabled!!! Have a question about this project?

But things would be less cluttered and not buried in obfuscating nested conditionsl blocks. //#define Z_probe_Servo //enable if you have a servo sensor on Z Notes. Without this, you may accidentally miss the bed when homing Z. — Yes. Disable endstops. Website. Mechanica Firmware – Marlin. Thanks for the software, I'd be very unhappy without it. This prevents your Z homing from occuring without prior X and Y homing. 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 … Where do I enter my values here?

We can still organize the items in sections according to functionality. #define Z_SAFE_HOMING • Uncomment line 110. Sign in Secondly disable the Z_MIN_PROBE_PIN option as below. @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. //===========================================================================, //Can use any sensor type Z_SAFE_HOMING_X_POINT and Z_SAFE_HOMING_Y_POINT are used only when you home all axes with G28 command. < all servo settings go here(sled options, other servo stuff)> 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. To enable safe z homing disable homing override and provide a X,Y coordinate of your Z endstop pin. Because, the new extruder is stopping slightly off the y-axis when homing. 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. Had zero effect on the stated issue. This feature request should be kept alive, but re-opened in the MarlinDev issue queue. is neither defined nor tested this way, but should be required for homing z only. // To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING. Usage M121 . I don't consider the time it takes to move from one instruction to the next as inactivity. // Example: To park the head outside the bed area when homing with G28. It is therefore recommended you update to 1.1.0-RC7 or start tracking along with RCBugFix. // // For a servo-based Z probe, you must set up servo support below, including 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. This is a bug apparently in 1.0.2-1. It will move up a little twice when it is homing Z. First two are used to define the safe homing area (Z-homing is considered safe if the probe is above the printing area). 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. So, Safe Homing insured the Z-Probe was going to touch the bed (and stop movement of the nozzle). Would these be the release candidates listed as "Not for production use – use with caution!"? // // For a servo-based Z … #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area.

Ender3 Pro Octopi Marlin [2.0.5.4] SKR1.4 turbo w/220 … It will not smash down into your spoil board. 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. @Nanox z home xy is only used for homing order z up xy preheat z. #endif // Example: To park the head outside the bed area when homing with G28. M121 - Disable Endstops control Disable endstops and keep them enabled when not homing. // Use “Z Safe Homing” to avoid homing with a Z probe outside the bed area. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. @thinkyhead Tried it. This prevents your Z homing from occurring without prior X and Y homing. Already on GitHub? It is going out of the standard 20x20 cm bed. Like I say, I haven't looked at the code real carefully to verify this, but this does seem like a reasonable request. #endif, //=========================================================================== //=========================================================================== You signed in with another tab or window. Successfully merging a pull request may close this issue. 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. Thanks tho for the quick answer. There was an error in 1.0.2-1. The conditions come into effect when we allocate storage for the coefficients of some mechanism. 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. If homing is needed the LCD will blink the X Y Z indicators. ), and DEFAULT_STEPPER_DEACTIVE_TIME? They are all ignored when the printer is homing. Without this, you may accidentally miss the bed when homing Z. //=========================== Manual Bed Leveling =========================== // // To use a separate Z probe, your board must define a Z_MIN_PROBE_PIN. 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. Change DEFAULT_STEPPER_DEACTIVE_TIME to 300 for a better experience. They can be used for homing … #If Enabled(Z_probe_Servo) // // For a servo-based Z probe, you must set up servo support below, including This may have side-effects if using SD_ABORT_ON_ENDSTOP_HIT. By clicking “Sign up for GitHub”, you agree to our terms of service and //it is highly recommended you let this Z_SAFE_HOMING enabled!!! DEFAULT_STEPPER_DEACTIVE_TIME is also set to its default. 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). I'm not joking. 1.0.2-1 is stable in the sense of - No error has been fixed since 18 month. Until then, they are just defining preprocessor names. 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. Examples. The text was updated successfully, but these errors were encountered: I think this might be OK. Uncomment Z_SAFE_HOMING. So if you are not running G28 it is ignored. 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. Does not work, still attempts to home Z at X=0, and Y=0. 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). @thinkyhead I left most things things at their defaults. ok, that didn't work, but it gave me a hint to something that at least compiles. The result of homing the z-axis should thus place the build surface at the z=0 plane. Already on GitHub? Notes. But the history of the Safe Homing was because the probe offset from the nozzle was causing problems. Z_SAFE_HOMING_X_POINT and Z_SAFE_HOMING_Y_POINT are used only when you home all axes with G28 command. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Before uncommenting After uncommenting //#define CUSTOM_PROBE #define CUSTOM_PROBE • Go to line 379 and set X offset to mount offset (recommended mounts use -40 for the X offset.) #define Z_probe_mech_endstop //leave enabled unless you have a special type of endstop, #If Enabled(Z_probe_Prox) 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. //==============================Z Endstop Options =========================== I haven't looked at the code real carefully to verify that. 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. If you don’t want that then you … As a side-effect, X and Y homing are required before Z 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. It's fixed now. #If Enabled(Z_probe_mech_endstop) PS: It would be great to have a skeleton for this configuration in the … Uncomment Z_SAFE_HOMING. Which means a G28 Z will result in all three axes being homed instead of just Z. Tricky, as there have been ~800 patches since 1.0.2-1. We’ll occasionally send you account related emails. 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. So we should work on this in the dev branch for 1.2 and perhaps it can also get into 1.1.1. 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. to your account. • Go to line 380 and set Y offset to mount offset (Recommended mounts use -10 for the Y offset.) For example, Will both lead to the unhelpful "Home X/Y before Z" error. So I'm curious. @Nocturnal42 Neither do we. This issue has been automatically locked since there has not been any recent activity after it was closed. The other X and Z axes are OK. Personally, I don't consider the time it takes to move from one instruction to the next as inactivity, but there it is. Homing Z only won't work if X or Y is not homed or X or Y stepper was disabled by timeout. Please open a new issue for related bugs. < all prox settings go here (including alt z min probe, Z_safe homing, etc)> So, I would eliminate all of the #if/#endif from the Configuration section. 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. I hope they will enable this in marlin. You signed in with another tab or window. It probably would be better stated as a carriage mounted probe. What are your configured settings for DISABLE_X (etc. Yes i can do that but, when i leveling (G32) with gama min homing active, its make autohome all axis. 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? #define Z_SAFE_HOMING_Y_POINT ((Y_BED_SIZE) / 2) // Y point for Z homing when homing all axes (G28). // With this feature enabled: // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. The difference compared to Configuration.h is that it offers us more detailed customization options, and experimental or in development functions. 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. 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. //#define Z_probe_Prox //enable if you have a prox sensor on Z 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 give that a try and let us know what happened. #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 (40*60) and HOMING_FEEDRATE_Z from (4*60) to (8*60). By clicking “Sign up for GitHub”, you agree to our terms of service and If you homed the Z-Axis in a location where the Z-Probe would miss the bed, really bad things happened.
