After a G29 the leveling data is only stored in RAM. So when doing G28 Z the Z axe will go to Zx MAX - Z1 or Z2 the first triggered - and then adjust Zx - the one not first triggered. Someone point me in the right direction. Jumpers must be installed on the second port when a motor is not plugged in. I see to possible scenarios (or three). However, bugfix-2.0.x now has Z_STEPPER_AUTO_ALIGN which adds a G34 command to align the ends of the X axis to the bed surface using dual Z steppers and the attached probe. TMC lib is 0.7.1 Have a question about this project? For automatic probe-based leveling enable one of the AUTO_BED_LEVELING_* options instead. I upgraded my X5S to Ramps1.4. Yes, it would be done every time G28 is run. I activated DualZMotor and can now use DualZ Endstops. When using a bed leveling sensor you'll not be able to put those switches to Z min, because you are using the leveling sensor, so you need to put them to Z MAX. I wanted to be able to place the probe in any arbitrary point on the bed/PCB and start the leveling. My second Z stepper motor is connected to the previously unused E1 stepper controller on my RAMPS 1.4 equivalent board. Bilinear bed leveling with Standard Hot End, BL Touch v3.1 (using Z Min port as endstop), Dual Z steppers (Z0=Z, Z1=E1), BTT TFT35 v3 and BTT SKR1.4 Turbo board - TMC 2209 UART mode. Please open a new issue for related bugs. I'd hate to have to drive my bed to the opposite limit and back every time I start a print- it takes awhile for the bed to move the 300mm or so there and then back again. To home with the probe enableZ_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN. to your account. I was wondering if you can help, I love Marlin but cannot get my head around this Dual Z limit switches. Use G29 S2 to save the Z value and move to the next point. I have the small picture framing clips (not the bulldogs!). Anyway, it would be nice to have two switches set up where each motor could be driven until it's respective switch is tripped to auto reset the main bed level. (Marlin 1.x) With S3, the (1…n) Y count of the mesh value to modify. # define LCD_PROBE_Z_RANGE 4 // Z Range centered on Z_MIN_POS for LCD Z adjustment # define LEVEL_BED_CORNERS // Add an option to move between corners # endif /* * * Commands to execute at the end of G29 probing. *View All Steps for S… OK, I got sidetracked by a couple printing jobs so I had en't had a chance to look at this yet. Nope. I'm using Marlin RC7 and I enabled Auto Bed Leveling Grid option. You must be homing in the - direction. On my machine I home in the + direction with the Z_MIN and the Z_MAX endstops at the top. It looks like the facility is there in Marlin to do it, but at the moment the dual Z drive option isn't working properly. #if ENABLED(DUAL_Z_STEPPER) #endif. I would still want to use the BLTouch for homing and probing. Press the controller button to save the Z value and move to the next point. Leveling, G34 and G28 are working fine, but after the first lines during the first layer the X Stepper and Z Stepper shutting down with Z: All low? I followed this, YouTube - Setting Up Auto Bed Leveling (Tevo Tarantula), for setting up the auto bed leveling sensor but it just got me messed-up even more, see Tevo Tarantula incorrectly auto leveling of bed. How to level your bed with the dual z min. where do I go to change the direction of the stepper motors for dual Z? I'm running BLTouch, plug into End stop min, and would like to add this feature, to my Marlin 1.19, but don't understand the full setup, as it so confusing, can you post what needs to be altered in Config.h and Config.adv.h, please if you have the time. Any of the other five endstops can be assigned to Z2. This issue has been automatically locked since there has not been any recent activity after it was closed.

You signed in with another tab or window. #define Z_DUAL_STEPPER_DRIVERS Only one of the ports can be used for independent motor leveling. Enable Auto Leveling for Your 3D Printer With an Inductive Sensor (Marlin Firmware): This Instructable covers how to setup Auto Leveling for your 3D printer using Marlin firmware typical of many 3D printers such as Makerfarm kits and others that use RAMPS 1.4 + Arduino based controllers with an Inductive sensor. I had to modify the probe holder by zenmaster a bit to account for my servo horn being a tad to wide and chisel shaped, not fitting in the original design. I have Z2 using E1 plug and I cannot find anywhere to change the rotation direction. JoelLisenby's GitHub TEVO-Tarantula-I3-Marlin-Firmware. Use the XMax end stop pins for the Z2 end stop switch. I have set Marlin 2.0.x on a SKR Pro v1.1 with TMC 2209 for a dual pellet extruder custom printer. Any of the other five endstops can be assigned to Z2.
