Rough Diagram _X_ _Y_ _Z1_ _Null_ _E0_ _Z2_ After replacing the belts with lead screws I need to pass X Y on 1/4 step. how to modify microstepping directly in marlin? If you have an MKS BASE with Heroic HR4982 stepper drivers then you would first set your MOTHERBOARD to BOARD_MKS_BASE_HEROIC. @Roxy-3D - I'm out of ideas on this one. Ok, hopefully this clarifies a bit more from what I have gotten via "translation" and trial and error regarding dual Z motors. Add to wishlist Search for: Product categories. Yes, I also was the one who added them in the first place. If that same combination sets X micro-stepping to 4x (in testing, G1 X... will move farther) then you have non-Heroic drivers. Already on GitHub? But it would exhibit the same behavior. Z-Axis doesn't work only during printing. to your account. Line 496: Enable this since we have 2 z stepper motors. Thanks! Are they A4982 or are they HR4982? There's not an obvious firmware reason why they'd rotate at different speeds since both step pins are written with the same macro. @Phantom-Code Thank you! I just tried Marlin bugfix-1.1.x (c262ea9) with this configuration. https://www.youtube.com/watch?v=sZuyGD4ciwk, Hi, you are on the right way. It's still working via Octoprint and the TFT works however it only sees its internal sdisk atm. one of the motors is turning further than the other per demanded distance and the bed goes out of true. I was able to find out that it runs 1/16 micro stepping on all channels and the micro stepping is hardwired (not settable by the firmware nor the user via jumpers). Just got the skr 1.4 turbo and have been pulling my teeth trying to configure it to work with my Ender 5 plus. [1.1.x] Add BOARD_MKS_BASE_15 with digital micro-stepping, [2.0.x] Add BOARD_MKS_BASE_15 with digital micro-stepping. #define Y_DRIVER_TYPE TMC2209 Warranty & Support Information. You signed in with another tab or window. Rough diagram _X_ _Y_ _Z1_ _Z2_ _E0_ _Null_ You need only the jumper on MS3. The skr 1.4 has Z0 and Z1 in addition to E0 and E1. This value should be set to the total number of E stepper motors on the machine, even if there’s only a single nozzle. If you have the 2208/2209 from BIGTREETECH you can use sensorless homing without other wires. Tried to enable the "#define Z_DUAL_STEPPER_DRIVERS", from which the second motor is operating, but he has mad speed. Well, I cant tell about other boards but the MKS BASE v1.5 that I have can control its microstepping pins. Does it matter if I change that value to 0? Marlin - Rumba - Dual Z drivers, z movement breaks movement on all axis December 12, 2015 12:50PM Registered: 4 years ago Posts: 7 ... And oddly after trying to move the Z motors neither X or Y axis motors would work after that. This fix work well on my Sunhokey Prusa I4. pins_RAMPS.h.swapped.zip. works However adjusting these settings for the X, Y, and Z axis is often unneeded, unless all other options such as tightening or loosening belts has been tried. With these drivers you can only set 1x, 8x, 16x, or 128x micro-stepping. TMC lib is 0.7.1. for marlin 1.1.9 - does this work on MKS Gen L board, setting Z_DUAL_STEPPER_DRIVERS using E1 as Z2? Alignment of dual Z-axis steppers. @JRosello it should be damn near the same, other than E-Step values I think. Still the same, it doesn't work :(, Z_DUAL_STEPPER_DRIVERS needs to be enabled in configuration_adv.h. A fresh perspective is needed. Align multiple Z stepper motors using a bed probe by probing one position per stepper. Post by chris33 » Sat Nov 01, … Technical Support: TH3D Community Support. share | improve this question | follow | edited Jan 12 '19 at 15:11. Did you transfer your machine specific items to the config files that came with 1.1.0 ? 3D printer stepper motors only going one direction and skipping in the other. on/off. The only thing I can think of that the firmware change might have affected is the step pulse width to the controller chips. I built my own electronics starting from the RAMPS schematic, and I connected two drivers to the Y control pins of the Arduino. Z motors spin at different speeds in same direction And if you find that you have non-Heroic stepper drivers, then we will need to add a new board, BOARD_MKS_BASE_15. You must use the M671 command to define the X and Y coordinates of the leadscrews. Should I open different issue for my case? I'm actually about to compile bugfix and see what I can do about it then do it all over again for my Ender. A fresh perspective is needed. Instead of messing with regular endstops I chose to use Z-Min as the BLTouch Probe pin for my Z Probe and End Stop. When I have more time I'll post my full Marlin configs and pictures here and on Thingyverse. Ive built 2 printers from scratch so know the basics of setting up the configuration.h and all the other stuff that will need changing. For Heroic HR4982 steppers the only allowed values are: And for other drivers the allowed values are: If you find that M351 S1 X0 plus M351 S2 X1 sets X micro-stepping to 128x (in testing, G1 X... will move less far) then you have Heroic drivers. @thinkyhead , @Roxy-3D - I'm out of ideas on this one. Press question mark to learn the rest of the keyboard shortcuts Contain V1.1 MKS-Gen2Z; USB line Supporting products, not including, need to purchase another: 4 (5) stepping motor: 42 motor with wire Limit switch 3: MKS limit switch Motor drive 4988: 4 or 8825 Display 1: 2004 or 12864 Hot bed 1: MK3 @shawnsm any chance you can share your configs? //A single Z stepper driver is usually used to drive 2 stepper motors. @Bob-the-Kuhn, I'll try your seggestions ASAP. // The next unused E driver will be assigned to the second Z stepper. how to modify microstepping directly in marlin? I set X2_MIN_POS to 80 (this prevents the second extruder colliding with the first) and X2_MAX_POS to ~350 (this is the distance between … #if NUM_Z_STEPPER_DRIVERS > 1 I'll as SKR arrives... damn a month and a half waiting. Set Configuration.h like: Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Any thoughts? Do both motors turn in the same direction at the same speed? By clicking “Sign up for GitHub”, you agree to our terms of service and If you find that you have HR4982 drivers, then you should set MOTHERBOARD to BOARD_MKS_BASE_HEROIC. 9. I wonder if this is why there are apparently more steps than should be. #define E0_DRIVER_TYPE TMC2209, My single motor dual Z Marlin Configuration_adv.h: Do both motors turn in the same direction at the same speed? 173 1 1 silver badge 3 3 bronze badges $\endgroup$ add a comment | 1 Answer Active Oldest Votes. Top. pins_RAMPS.zip. Better idea is the second one on E1. Unfortunately it means you'll have to translate the config files as names and options have changed between RC8 & 1.1.x. My DUAL DRIVER DUAL Z Motor Configuration.h: Re: RAMPS 1.4 & Marlin driving dual Y steppers. In the video at 2:36 you can notice how easy the motor stops by hand, with a simple touch, the torque is minimal there. Save your current pins_RAMPS.h file and then drop in one out of the ZIP file. If there's just one set of header pins (or one Z-motor socket of some other kind) ... Z Axis getting stuck with Marlin 1.1.0-RC7. Marlin 1.1.? @Phantom-Code — Please share your pins file. If turning the current up and setting MINIMUM_STEPPER_PULSE to 10 doesn't help then you could try moving the logical stepper channels to different sockets. 3. i.e. in later versions of Marlin, this changed to NUM_Z_STEPPER_DRIVERS which we would want to set to a value of 2 . Hello Enable the DUAL_X_CARRIAGE define and configure the X2_ENABLE_PIN, X2_STEP_PIN, X2_DIR_PIN to be the expansion header pins you have used. I didn't read this issue even though you flagged me on it. Add to cart. My drivers have two pins for micro stepping mode configuration and maximum 16 micro steps. Just ZIP them up and drop them on your reply. @shawnsm Thanks!! Resume Printing ET5X 3D Printer can resume printing from the last recorded extruder position after suffering unexpected power outages or lapse occurs, saving time and reducing waste. @Phantom-Code — Can you tell what kind of stepper drivers are on your board? You will need to increase the current for the z axis, but not double it. @thinkyhead you cut out these pin definitions from the bugfix-1.1.x branch yourself. ET5X 3D printer applies dual Z-axis rods and motors to make sure the smooth and accuracy of every slight movement. Please try Marlin RC8. If you want use endstops you need to cut the drag pin. In that case I guess we'll add MKS_BASE_15 for a board that has digital micro-stepping, but not the HR drivers. eShapeoko 1.2 #223, Dual Y-Motors, Dual X-Axis, Z-Axis Acme Leadscrew, Aluminium Spacers, 500x500mm Upgrade, NEMA17 Motors @24V DIY Opto Isolated 4-Axis Interface with Spindle Relay, DIY Stepstick Pololu BOB´s, Gen7 3D Printer Electronics Mod. Successfully merging a pull request may close this issue. I'm using dual Z with the TMC2130 on all axis. I've installed them both and updated the firmware and the machine runs great! People using RAMPS with RepRaps, ORD Bots and other 3D printers wire their two Z motors in parallel. Marlin 1.0.? He's running dual Z drivers on a MKS Base v1.5 controller and seeing the following: I'm sorry. And what if I do have an ATX PSU? 4. Hmmm, I'm sorry, but I didn't mentioned yet, that I used Marlin 1.0.0 provided by Sunhokey. #define X_DRIVER_TYPE TMC2209 Thanks for the update. If you need any help, please let me know. Using ATX PS on/off via RPi/OP happens upstream of control board so is completely independent of POWER_SUPPLY feature of Marlin. If you use no UART Mode then you need to set the vref up to the double of the vref for the first motor. Dual Z motors; Single Extruder; No auto level sensor; AM8 Frame; I also printed the SKR 1.3 mount.STL made by neb1 from Thingiverse, in order to mount the board on the AM8 2020 aluminium frame. #if NUM_Z_STEPPER_DRIVERS > 1 Two, 2 Z axis motor can be connected to the Z motor 1, Z motor 2, other functions and MKS-Gen is the same. Will also have NEO Pixel info and using "extra" pins for fan control as these are things that bugged me... P.S. Wasted lot of time until found your solution. It's about as easy to hack the hardware, too. By default Marlin will assume separate nozzles all moving together on a single carriage. I was just looking through the A4988 data sheet and it'll try to recover from an over current event every 20-40uS. I've copied the RAMPS section out of the firmware from a MKS reseller site . If the stepper current is too low then we'd be losing steps, not gaining them. 4. https://www.youtube.com/watch?v=sZuyGD4ciwk. Swapping stepper cables moves the extra speed to the other stepper. We’ll occasionally send you account related emails. #define Z_DRIVER_TYPE TMC2209 // This will STILL send juice to Z2 but don't use if using 2 Drivers It seems to be driving ok apart from the steps per unit seem to be out. Test the Y axis pololu with both the X and Y motors, then move the Y axis pololu to the place of the X axis pololu and test with both the X and Y axis motor (do not unplug motors or drivers while they are powered). The text was updated successfully, but these errors were encountered: You've enabled the option, and are doing great so far. they are programmed on 1/16. Which versions of the MKS BASE board has them and which don't? //#define Z_MULTI_ENDSTOPS The biggest improvement in this kit are the Trinamic drivers, which make the machine run smoothly and quietly. Without a doubt, setting the amount of steps a stepper motor needs to move per mm is important for dimensional accuracy. The way I read emails and issues caused me to miss this one. Look to enable “Z_DUAL_STEPPER_DRIVERS” in Configuration_adv.h in Marlin. Do both motors turn in the same direction at the same speed? can you tell me how to modify on the program MKS BASE v1.5? I'm doing the same mod on my SWX1 and having some issues. Connect 2 motors on one side of X in series to Z stepper driver and connect 2 other motors in series to E1. By clicking “Sign up for GitHub”, you agree to our terms of service and Tevo were kind enough to send along a dual axis upgrade kit as well as the TMC2208 upgrade kit. I'm not an electronics engineer, just a programmer. You can also try setting MINIMUM_STEPPER_PULSE to 10. Successfully merging a pull request may close this issue. Note that the Z driver (drive 2 on Duet2) has a dual socket wired in series for powering two z motors at once. I used your configuration files, downloaded it and printed out a list of the pins and the functions assigned to them. How to make driver of E1 for motor Z2 on RAMPS 1.4? I will try my best to help out with the configuration. I had custom updated Marlin 1.1.3 which was work well until I updated it today to 1.1.8 and got the same issue - Z axis motors rotated with different speed. Also, I can upload ZIP, if it still needed :) On 1.0.x torque is high enough, I can't block it even with three fingers when it connected to the axis rod. See M422 for Z-Stepper automatic alignment parameter selection. The text was updated successfully, but these errors were encountered: see this video See if it's better behaved with this file when using bugfix-1.1.x Here's a long shot. 0scar ♦ 24.7k 6 6 gold badges 38 38 silver badges 103 103 bronze badges. I've got mine printing great finally, now some annoying little issues with the skr 1.4 not jiving with the tft 3.5 v3 with SD card slots and what not. For my part I try to do the opposite. // Uncomment this option to use a separate stepper driver for each Z axis motor. He's running dual Z drivers on a MKS Base v1.5 controller and seeing the following: Since it's an MKS product we can't get a schematic for it.
