You'll find it in configuration_adv.h. Swap the two connectors of one coil to reverse the steppers direction. G28 disables bed leveling. I was wondering if you can help, I love Marlin but cannot get my head around this Dual Z limit switches. privacy statement. Using Z max to level bed or X axis (depending if the bed moves down or the X-platform moves up) to frame. # 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. Thus you will still be using one of the extruders drivers to become your second Z … Produce a mesh report (see examples below). Repeat steps 3-4 until completed. I'd like to jump in here for a second. You might see if it'll work if homing in the - direction. Use M502 to reset the bed leveling data (and other settings to defaults). 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. How to level your bed with the dual z min. 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. The Megatronics board looks to have 6 stepper drivers, 3 for XYZ axis and 3 for extruders. with that in mind, is this process a part of the G28 command and done every time? It's homed first if the direction is +. ... and/or Z axes. Then raise the bed up and do a ABL or MBL in the future. (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_MIN endstop. After a G29 the leveling data is only stored in RAM. Press the controller button to save the Z value and move to the next point. (See also M421.). Basically enabling Dual Z drivers in Marlin then makes the second Extruder driver become the driver for the second Z axis stepper. 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. I wanted to be able to place the probe in any arbitrary point on the bed/PCB and start the leveling. #define Z_DUAL_STEPPER_DRIVERS Dual Z End Stops on Mini E3 V2 in Marlin? To home with the probe enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN. 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. Yes, it would be done every time G28 is run. However, right below that the Z didn't have it. I'm using Marlin RC7 and I enabled Auto Bed Leveling Grid option. 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'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. So, is this something that is already supported? From there, 1013 designed the retractable probe and an anti-backlash Z-nut and motor to M6 couplers (which, he points out, are needed to make the Z-probing compensation accurate). For automatic probe-based leveling enable one of the AUTO_BED_LEVELING_* options instead. 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. When you build Marlin you have the option to include one of 5 different bed leveling systems. I'm using dual Z with the TMC2130 on all axis. Hello, I am configuring Marlin 2.0.x with sensorless probing which works fine. Above the given Z height, leveling compensation will no longer be applied. For homing, you are correct. Positive values are away from the bed; negative values are closer. The proper solution is a 2nd Z end stop switch for the Z1 leadscrew, combined with Dual Z Steppers configured in Marlin (Configuration_adv.h and Configuration.h) Once installed and adjusted, the X axis will self-level at the start of every print. Already on GitHub? The Z_MIN endstop will NOT be used. 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. Any of the other five endstops can be assigned to Z2. There needs to be a tutorial on how to do this, to some degree. We’ll occasionally send you account related emails. Hi, First of , good job on the firmware, it has come a long way since I started using it (about 2yrs ago.) You must be homing in the - direction. Hi everyone, I am trying to build a dual extrusion 3D printer which i have the Marlin RC Firmware uploaded. Mesh Bed Leveling (MBL) allows interactively measuring a Z height mesh without a bed probe. If yes, how is it enabled? Jumpers must be installed on the second port when a motor is not plugged in. It is likely that one of the Z-Axis is out of level after a while. For example I … Normally this is caused by running into something but sometimes I have no clue what the cause is (probably running into something when I'm not there.) Sign in 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 am using a mechanical end stop on the z axis with leadscrews and dual stepper motors. Please open a new issue for related bugs. When you home, does it use the two z axis switches? Press J to jump to the feed. A single Z endstop is supported. To home with the probe enableZ_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN. It looks like, for the moment, it is not possible to home Z1 + Z2 using a leveling sensor. I would still want to use the BLTouch for homing and probing. By clicking “Sign up for GitHub”, you agree to our terms of service and I have configured the Extruder count in Marlin to 2, changed the temp sensor settings, but i couldnt get my slicer software, Matter Control to detect it as dual … My second Z stepper motor is connected to the previously unused E1 stepper controller on my RAMPS 1.4 equivalent board. I have set Marlin 2.0.x on a SKR Pro v1.1 with TMC 2209 for a dual pellet extruder custom printer. Use G29 S1 to move to the first point for Z adjustment. You can home the Z axis with either the probe or the endstops. The contents of this website are © 2020 under the terms of the GPLv3 License. This is what I have in the platformio.ini A nice feature would be to use both Z_DUAL_ENDSTOPS (2 Z endstops) for initial leveling and the probe for ABL / MBL. Now for bed leveling I will consider the nozzle of E0 as the actual probe? where do I go to change the direction of the stepper motors for dual Z? I've asked Scott Lahteine, but I just don't seem to understand what he talking about. On my machine I home in the + direction with the Z_MIN and the Z_MAX endstops at the top. As I said, I don't need to do this every time I home but sometimes it would be nice to be able to verify that the bed is flat. You must be homing in the - direction. Set X_DUAL_STEPPER_DRIVERS to use a second X motor. Requires the MESH_BED_LEVELING option in Configuration.h. The Z axis is homed last if the direction is -. G32 Probe Z and calibrate with FPU probes the bed at 3 points and updates transformation matrix for bed leveling compensation. To home using the Z endstop enable Z_MIN_PROBE_ENDSTOP. Would be nice to be able to configure if min or max will be used. 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. Does Repetier Firmware support dual Z stepper controllers? It works very well with my BLTouch for bed leveling but over time the two sides drift away from each other. Use the controller wheel to adjust Z so that a piece of paper can just pass under the nozzle. 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. Have a question about this project? The Z_MIN endstop will NOT be used. What about the probe, when does it come into play? JoelLisenby's GitHub TEVO-Tarantula-I3-Marlin-Firmware. 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). It doesn't seem like it would require that any offsets be saved, just move each axis motor till the associated end stop trips and zero them there. I tried the E1 direction in config.h but that didn't work. With DualZ Motor control and DualZ Endstops each ZMotor is driven until it reaches its own endstop. You signed in with another tab or window. (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 . See M422 for Z-Stepper automatic alignment parameter selection. The re-assigned (Z2) endstop has to be physically attached to one of the Z axis rails. By default, however, Marlin needs to home the X and Y axis before allowing a G29 (auto-leveling) to be performed. I'm using a proximity sensor LJ12A3-4-ZBX and an MK3 Heated Bed. 1 year ago I have been using it and it is better than marlin in most regards imo Prints look better can print quieter and run faster Easy to adjust config file instead of having to reflash firmware The only thing I don’t like as well is the automatic bed leveling *View All Steps for S… I have the small picture framing clips (not the bulldogs!). Similar to AUTO_BED_LEVELING_BILINEAR with PROBE_MANUALLY but uses less SRAM. Mesh Bed Leveling using an LCD controller: (Requires LCD_BED_LEVELING). Mesh Bed Leveling from the host: Use G29 S0 to get the current status and mesh. Skip navigation ... MKS Gen 1.4 - Dual Z steppers with Marlin firmware (Part one) - Duration: 8:30. to your account. A rig to mount a small 9G RC servo, with an arm mounted Z-endstop, next to the extruder on a K8200/3Drag to enable the Auto bed leveling feature in recent Marlin. How to level your bed with the dual z min. I activated DualZMotor and can now use DualZ Endstops. It's homed first if the direction is +. I set Z_MAX_POS so that the nozzle is about 10mm above the bed at Z0. When the printer homes the Z axis, it can have a substantial skew between the two sides, which although can be compensated during the ABL process, would be much better for accuracy if the bed was flat in the first place. #if ENABLED(DUAL_Z_STEPPER) (Marlin 2.x) With S3, the (0…n-1) X index of the mesh value to modify. Successfully merging a pull request may close this issue. TMC lib is 0.7.1 This could be set up for any axis with two drive motors. Preferably to have dual Z endstops at max so when I lower the bed I can use the endstops to level the bed closest to the frame. Only one of the ports can be used for independent motor leveling. As usual with this arrangement, you must use M584 to assign the 2, 3 or 4 drivers to the Z axis Note that the Z driver (drive 2 on Duet2) has a dual socket wired in series for powering two z motors at once. The Z axis is homed last if the direction is -. Hi Bob, I was wondering if you can help, I love Marlin but cannot get my head around this Dual Z limit switches. [Support] 2 motor Z-axis leveling switches and probe for homing. 【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. Thanks for this. Run it NC (Normally Closed). 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. I would like to use optical micro switches and make up some flags, so there no interference if the bed move up or down. If homing in the + direction then Z1 is the Z_MAX endstop. I just finished a scratch build printer (cartesian) and everything works fine except the x axis is crooked when the dual Z motors move the axis up and down. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. An added bonus for this is the limit on Z max. You have to use M500 to save the bed leveling data to EEPROM, otherwise the data will be lost when you restart (or reconnect) the printer. 1 year ago. The re-assigned (Z2) endstop has to be physically attached to one of the Z axis rails. I haven't tried that method. Manually modify a single point with X Y Z parameters. MBL uses the mesh to compensate for variations in height across the bed. Adjust Z so a piece of paper can just pass under the nozzle. I have two motors and drivers on my Z axis. #endif. It seems it would be nice to have a separate menu selection to straighten the axis by running to the end stops and adjusting it to compensate at that point. I seem to remember reading about this here awhile back and would like to find out if it's a doable thing. Workaround: I upgraded my X5S to Ramps1.4. Align multiple Z stepper motors using a bed probe by probing one position per stepper. But the problem is that when the nozzle should go up it goes down and when the nozzle should go down it goes up. I then looked at config_adv.h and found that the dual X and dual Y had the reverse motor option. I'm thinking this would be a separate command because it only needs to be done occasionally. What I ended up doing was completely rebuilding my X and Z axes. If there’s an existing mesh, you can send M420 S1 to use it. (Marlin 1.x) With S3, the (1…n) X count of the mesh value to modify. This issue has been automatically locked since there has not been any recent activity after it was closed. Each leveling system comes with its own set of options and makes G29 behave differently, so documentation for these G-codes is divided up into 5 separate pages. Use the XMax end stop pins for the Z2 end stop switch. The only tool required is a piece of paper or a feeler gauge. 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. But I do have questions? Marlin has a feature, Z_DUAL_STEPPER_DRIVERS that automatically uses the unused E stepper controller. I see to possible scenarios (or three). I guess I just don't understand the homing process as it is currently implemented with dual motors and end stops. Nope. With dual Z stepper drivers and Z endstops it would be good to be able to level and / or home with the dual endstops/limit switches. I have a drawing where I … OK, I got sidetracked by a couple printing jobs so I had en't had a chance to look at this yet. Press question mark to learn the rest of the keyboard shortcuts Use M501 to reload your last-saved bed leveling from EEPROM. That is optional. Any of the other five endstops can be assigned to Z2. You'd have to change a few of the defines and disable ENDSTOPS_ALWAYS_ON_DEFAULT. Adjust Z so a piece of paper can just pass under the nozzle. 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. Even though this makes sense in the grand-scheme of things, it was a nuisance in my case. I have a prusa i3 clone 3D printer, which is running marlin v 1.1.8 and configured to use bilinear bed leveling. Set a global Z offset. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. 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. Hi guys. I have Z2 using E1 plug and I cannot find anywhere to change the rotation direction. (Marlin 1.x) With S3, the (1…n) Y count of the mesh value to modify. 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 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. # if ENABLED(LCD_BED_LEVELING) # define MBL_Z_STEP 0.025 // Step size while manually probing Z axis. Use G29 S2 to save the Z value and move to the next point. Dual Y axis provide a guideway for a more stable and level moving stage of the build platform. Someone point me in the right direction.
