z_safe_homing not working

I'm slicing with Simplify3D, but I've also tried Cura for Lulzbot and had the same issue. This means that the BLTouch, rather than the Z endstop switch, is used for determining where the minimum Z position is. Enable USE_PROBE_FOR_Z_HOMING. If I tell Z to home, both X and Y blast off away from their homes crashing to the opposite sides of their rails. I've recently tried to print some parts on our TAZ 6 printer, and the Z homing is not working properly in the starting script. This is important, but not the complete solution. I'm not sure what to tell you to do if that didn't work (other than the 12v all the time). // Use "Z Safe Homing" to avoid homing with a Z probe outside the bed area. I hope Daniel considers making this the default setting for the non BL Touch firmware. I get a correct home direction with X and Y when I instruct one at a time to HOME. Add 2 // in front of the MIN_SOFTWARE_ENDSTOP_Z line in your Configuration.h file as shown below. Not actually blaming Marlin 1.1.6 just made me nervous and returned to 1.1.5 as it was working best of all versions, with the features I liked and used. This is a safety feature that stops the probe from trying to deploy outside of the print bed, which could crash the nozzle into the print bed. You will need to make sure software endstops are DISABLED for Z after adding the probe. #define Z_SAFE_HOMING. :x: Z-endstop switch is NOT monitored while homing Z.:x: BLTouch is NOT deployed while homing Z.:heavy_check_mark: BLTouch is not monitored while homing Z. The reason I didn't use constant 12v is because I didn't have a source to connect it to. //#define Z_SAFE_HOMING is not enabled, this is advised to enable. This will let you adjust the Z to a negative number for your offset. It is not a problem that the sensor is not above the build plate during printing as long as it is above the build plate during the auto bed levelling sequence.. Homing does not necessarily need to be the (0,0) coordinate. #define Z_SAFE_HOMING • Uncomment line 110 - #define CUSTOM_PROBE • Go to line 401 and set X offset to mount offset (recommended mounts use -40 for the X offset.) Also, you have not defined the auto leveling area by setting the boundaries for probing (where the probe can reach). Enable Z_SAFE_HOMING. The first G28 // - Move the Z probe (or nozzle) to a defined XY point before Z Homing. Installing MKS SGen L v1.0 in my Ender-3 homing id not working for Z. I have a MKS SGEN L with BLTouch installed. • Go to line 402 and set Y offset to mount offset (Recommended mounts use -10 for the Y offset.) // // With this feature enabled: // // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. // Not working O // #define XY_FREQUENCY_LIMIT 15 // Minimum planner junction speed. #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. • Go to line 356 if you want to set printer name to display on printer LCD and then recompiling the firmware. Sets the default minimum speed the planner plans for at the end // of the buffer and all stops. This is not :x: because of the reason described in Option 3 point 3.:x: Z-endstop switch is NOT monitored when moving Z … Since I like the homing, just not in the middle of the bed, I modified the configuration to my needs by re-commenting the following line in Configuration.h //#define Z_SAFE_HOMING. It makes more sense to me for manual leveling. Usually, a printer homes on the endstop switches, from that coordinate an offset is defined in the firmware to move to the origin. Bed Leveling Bi-linear (allows saving Bed Leveling Data ( M500 or "LCD Menu" Store settings and restore using M420 S1 in startup G-Code ) // - If stepper drivers time out, it will need X and Y homing again before Z homing. This should not be much greater than zero and should only be changed // if unwanted behavior is observed on a user's machine when running at very slow speeds. I'm using the standard startup script, and the issue is with G28 Z. With Simplify3D, but not the complete solution still enabled Z after adding the probe work other.
