Personally, I don't consider the time it takes to move from one instruction to the next as inactivity, but there it is. I concur with @Blue-Marlin. You signed in with another tab or window. ), and DEFAULT_STEPPER_DEACTIVE_TIME? // Use “Z Safe Homing” to avoid homing with a Z probe outside the bed area. Disable endstops. A NOZZLE never goes off the bed unless something is configured wrong or there is a dump area. If i change gamma_min_endstop to Not Connected, i cannot home Z normally. Homing is required before G29, M48, and some other procedures.. //=========================== Manual Bed Leveling =========================== make Z safe homing independent of auto bed leveling. G32 uses the probe points defined in eeprom. So if you are not running G28 it is ignored. Thanks tho for the quick answer. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. M121. Already on GitHub? PS: It would be great to have a skeleton for this configuration in the … It is therefore recommended you update to 1.1.0-RC7 or start tracking along with RCBugFix. //#define Z_probe_Prox //enable if you have a prox sensor on Z ok, that didn't work, but it gave me a hint to something that at least compiles. Homing Z only won't work if X or Y is not homed or X or Y stepper was disabled by timeout. Secondly disable the Z_MIN_PROBE_PIN option as below. We’ll occasionally send you account related emails. #endif, //=========================================================================== If you homed the Z-Axis in a location where the Z-Probe would miss the bed, really bad things happened. G28 disables bed leveling. Trial and error is the tactic to go. 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. So we should work on this in the dev branch for 1.2 and perhaps it can also get into 1.1.1. DISABLE_[XYZ] is incompatible with HOME_AFTER_DEACTIVATE and Z_SAFE_HOMING thinkyhead added PR: Improvement PR: Configurations labels Jul 4, 2017 Hide details View details thinkyhead merged commit b8066fb into MarlinFirmware : bugfix-1.1.x Jul 4, 2017 //===========================================================================, //Can use any sensor type #endif Which means a G28 Z will result in all three axes being homed instead of just Z. This feature request should be kept alive, but re-opened in the MarlinDev issue queue. Usage M121 . 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). //it is highly recommended you let this Z_SAFE_HOMING enabled!!! //=========================================================================== 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. Ender3 Pro Octopi Marlin [2.0.5.4] SKR1.4 turbo w/220 … 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. For example, Will both lead to the unhelpful "Home X/Y before Z" error. It is going out of the standard 20x20 cm bed. Please Help going nuts! //============================ Bed Auto Leveling ============================ 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. @thinkyhead I left most things things at their defaults. This prevents your Z homing from occurring without prior X and Y homing. So I'm curious. // You will want to disable Z_SAFE_HOMING above as you will still use the Z min endstop for homing. Without this option enabled the nozzle will crash into the bed when homing. Disable endstops. // To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING. privacy statement. M121 - Disable Endstops control Disable endstops and keep them enabled when not homing. 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. This issue has been automatically locked since there has not been any recent activity after it was closed. 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. Successfully merging a pull request may close this issue. Yes. Thanks for the software, I'd be very unhappy without it. 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. //Must use either servo or proximity sensor //#define Z_probe_Servo //enable if you have a servo sensor on Z Marlin [2.0.5.4 Z_Safe_Homing not centered, Bltouch going off bed. < all prox settings go here (including alt z min probe, Z_safe homing, etc)> ... Z_SAFE_HOMING. Z_SAFE_HOMING_X_POINT and Z_SAFE_HOMING_Y_POINT are used only when you home all axes with G28 command. But things would be less cluttered and not buried in obfuscating nested conditionsl blocks. 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. @Nanox z home xy is only used for homing order z up xy preheat z. is neither defined nor tested this way, but should be required for homing z only. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to … Notes. It will not smash down into your spoil board. , //=========================================================================== < all mech_endstop settings go here> Please give that a try and let us know what happened. 1.0.2-1 is stable in the sense of - No error has been fixed since 18 month. The safe X & Y point automatically get set to the middle of the bed. // // For a servo-based Z … By clicking “Sign up for GitHub”, you agree to our terms of service and What are your configured settings for DISABLE_X (etc. Like I say, I haven't looked at the code real carefully to verify this, but this does seem like a reasonable request. Reply to this email directly or view it on GitHub #2877 (comment). 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.) 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 use a separate Z probe, your board must define a Z_MIN_PROBE_PIN. Because, the new extruder is stopping slightly off the y-axis when homing. Examples. — 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. It probably would be better stated as a carriage mounted probe. 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. Mechanica Firmware – Marlin. The text was updated successfully, but these errors were encountered: I think this might be OK. I don't consider the time it takes to move from one instruction to the next as inactivity. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. If you're not using Marlin or newer versions of Marlin, then you should ignore this :) #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. I think it is because of the Z_Safe_Homing … So search and enable Z_SAFE_HOMING if using a BlTouch or probe. privacy statement. 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. You signed in with another tab or window. I'm not joking. If you want to hard code a location, you can do it by doing something like: Found it out myself already works perfect. 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. PS: It would be great to have a skeleton for this configuration in the Configuration.h file. Successfully merging a pull request may close this issue. First two are used to define the safe homing area (Z-homing is considered safe if the probe is above the printing area). #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. Had zero effect on the stated issue. It will move up a little twice when it is homing Z. So, I have played with the #defines explained below, but I couldn't even make any single mm difference by homing. Without this, you may accidentally miss the bed when homing Z. So, I would eliminate all of the #if/#endif from the Configuration section. // Only one of these can be on at a time. Now all I have to do is test it out. If you don’t want that then you … The other X and Z axes are OK. This prevents your Z homing from occuring without prior X and Y homing. The result of homing the z-axis should thus place the build surface at the z=0 plane. I don't know that it will work, but it has a fair chance of working. // To continue using the Z-min-endstop for homing, be sure to disable Z_SAFE_HOMING. Already on GitHub? #define Z_SAFE_HOMING_Y_POINT ((Y_BED_SIZE) / 2) // Y point for Z homing when homing all axes (G28). Notes. *_PROBE_BED_POSITION are used for auto-leveling only. Sign in Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Z_PROBE_BED_DISTANCE would be fine and for z max homing we even use this for a starting height after z homing … I haven't looked at the code real carefully to verify that. If using a Probe for Z Homing, enable Z_SAFE_HOMING also! 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. Until then, they are just defining preprocessor names.
