Yes, it would be done every time G28 is run. Use the controller wheel to adjust Z so that a piece of paper can just pass under the nozzle. where do I go to change the direction of the stepper motors for dual Z? I see to possible scenarios (or three). Have a question about this project? Any of the other five endstops can be assigned to Z2.

I'm still on 1.1.0 RC6 (@Alex9779 's Marlin-BigBox-Dual-RC build) In summary, I still think it's a bug in the firmware and I'm very tempted to try the new release and see if the problem goes away. 【Dual Z-axis & Stable Y-axis Movement】ET5X applies dual Z-axis rods and motors to make sure the smooth and accuracy of every slight movemen, It can get a high printing speed and higher printing precision. This is what I have in the platformio.ini I activated DualZMotor and can now use DualZ Endstops. I've been reviewing the Marlin issues list since the recent release of 1.1.0 firmware and a great many MBL issues appear to have been fixed. It is likely that one of the Z-Axis is out of level after a while. With this option enabled, by default Marlin will use the Z_MIN_PROBE_PIN specified in your board’s pins file (usually the X or Z MAX endstop pin since these are the most likely to be unused). A single Z endstop is supported. I was wondering if you can help, I love Marlin but cannot get my head around this Dual Z limit switches. With DualZ Motor control and DualZ Endstops each ZMotor is driven until it reaches its own endstop. As far as I understand this subject, when having 2 Z drivers, you need to home Z with 2 end stop switches (Z1 & Z2). I would like to use optical micro switches and make up some flags, so there no interference if the bed move up or down. The text was updated successfully, but these errors were encountered: It's called Z_DUAL_ENDSTOPS. A nice feature would be to use both Z_DUAL_ENDSTOPS (2 Z endstops) for initial leveling and the probe for ABL / MBL. You signed in with another tab or window. (Marlin 1.x) With S3, the (1…n) X count of the mesh value to modify. 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'm using dual Z with the TMC2130 on all axis. The Z axis is homed last if the direction is -. For automatic probe-based leveling enable one of the AUTO_BED_LEVELING_* options instead. 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. Manually modify a single point with X Y Z parameters. Align multiple Z stepper motors using a bed probe by probing one position per stepper. 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. Workaround: Dual Z End Stops on Mini E3 V2 in Marlin? Similar to AUTO_BED_LEVELING_BILINEAR with PROBE_MANUALLY but uses less SRAM. However, right below that the Z didn't have it. The Z_MIN endstop will NOT be used. I'm using a proximity sensor LJ12A3-4-ZBX and an MK3 Heated Bed. Use M501 to reload your last-saved bed leveling from EEPROM. Then raise the bed up and do a ABL or MBL in the future. The Z_MIN endstop will NOT be used. Mesh Bed Leveling (MBL) allows interactively measuring a Z height mesh without a bed probe. I would still want to use the BLTouch for homing and probing. Please open a new issue for related bugs. When you build Marlin you have the option to include one of 5 different bed leveling systems. By clicking “Sign up for GitHub”, you agree to our terms of service and Would be nice to be able to configure if min or max will be used. Dual Y axis provide a guideway for a more stable and level moving stage of the build platform. privacy statement. To home with the probe enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN. [Support] 2 motor Z-axis leveling switches and probe for homing. On my machine I home in the + direction with the Z_MIN and the Z_MAX endstops at the top. Skip navigation ... MKS Gen 1.4 - Dual Z steppers with Marlin firmware (Part one) - Duration: 8:30. If yes, how is it enabled? (Marlin 2.x) With S3, the (0…n-1) Y index of the mesh value to modify. If homing in the + direction then Z1 is the Z_MAX endstop. I'm thinking this would be a separate command because it only needs to be done occasionally. Swap the two connectors of one coil to reverse the steppers direction. Mesh Bed Leveling using an LCD controller: (Requires LCD_BED_LEVELING). to your account. Anet A8 Plus upgrade to Marlin 2.0.x Posted on October 23, 2019 by Thomas.Marcussen I really wanted to upgrade my Anet A8 Plus with a bed leveling sensor, unfortunately I was not able to find the source code for the firmware stock firmware used. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The Z axis is homed last if the direction is -. Set X_DUAL_STEPPER_DRIVERS to use a second X motor. But the problem is that when the nozzle should go up it goes down and when the nozzle should go down it goes up. Here below is an example of the Dual Ys with the invert direction option: And here is the section for dual Z right after, but without invert direction option as seen above. How to level your bed with the dual z min. G28 disables bed leveling. (Marlin 1.x) Modify some mesh points and view the new mesh: (Marlin 2.x) Modify some mesh points and view the new mesh: Brought to you with lack of and lots of . Use G29 S2 to save the Z value and move to the next point. See M422 for Z-Stepper automatic alignment parameter selection. I set Z_MAX_POS so that the nozzle is about 10mm above the bed at Z0. How to level your bed with the dual z min. You must be homing in the - direction. I just saw another possibly bigger problem. It works very well with my BLTouch for bed leveling but over time the two sides drift away from each other. You might see if it'll work if homing in the - direction. You can home the Z axis with either the probe or the endstops. I haven't tried that method. What I ended up doing was completely rebuilding my X and Z axes. Sign in 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.
