All you need to do is swap the cables Define #define USE_YMAX_PLUG. Yes, I cooked it from the scratch :) One-by-one, taking care about deprecated parameters. Z motors spin at different speeds in same direction Bla, Bla, Bla, If running TWO drivers for TWO Z motors, one for EACH Z axis then plug Z1 into Z1 and Z2 into E1. Usually if the pulse is too narrow then we'd be losing steps. Ok, hopefully this clarifies a bit more from what I have gotten via "translation" and trial and error regarding dual Z motors. Connect 2 motors on one side of X in series to Z stepper driver and connect 2 other motors in series to E1. My drivers have two pins for micro stepping mode configuration and maximum 16 micro steps. The 5160 can work with 60 V & up to 20A so you can say he has no limit. Merge in any Bukobot Configuration.h changes. I'm not sure if you go the answer to your question, but the short answer is that the NUM_Z_STEPPER_DRIVERS should be 1. The driver ICs are soldered to the board. #define NUM_Z_STEPPER_DRIVERS 2 // (1-4) Z options change based on how many 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. I have TMC5160 with this board and motors plugged into Z0 and Z1 are working but I am not sure if the vref needs upping as the stepper is now driving 2 motors? 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. Do both motors turn in the same direction at the same speed? 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. Hello Sunhokey Prusa i3 axis x, y, z? privacy statement. @thinkyhead I'm pretty sure I have A4982 drivers. 4. // The next unused E driver will be assigned to the second Z stepper. See M422 for Z-Stepper automatic alignment parameter selection. Another really far out idea would be to play with the pin assignments and see if we can find a pair of channels that rotate at the same speed. You don't have to tell the printer that there are two motors connected. It can get a high printing speed and higher printing precision. 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? (We're only supporting up to MKS BASE 1.4.). Works with the Ender 3, Ender 3 Pro, and CR-20 . Please send a photo of how the Z2 motor is attached to the controller. Disconnect the two Z motors from the belts/screws so the motors can turn freely. 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. I'd like to jump in here for a second. with little torque. So… please help! Bottom line, if you are using ONE driver for TWO Z Motors then plug Z1 into Z1 and the 2nd motor into Z2. Dual Z Stepper Motor Adapter w/Cable quantity. Increasing Vref might actually be a solution. The second 'Z2' Motor must plug to the E1 Port and UART make after your changes all needed things. Z0 and Z1 appear to run off the same stepper driver, but I can't find any information on how to enable Z1. Marlin firmware 1.0.x by Sunhokey. You can do this by pretending to just have one Z motor or go on to configure the G34 lines in configuration.h, As long as your HW is the same and VRefs are set the same you can just use this and BL-Touch Home off the center of the bed just fine. in later versions of Marlin, this changed to NUM_Z_STEPPER_DRIVERS which we would want to set to a value of 2 . I use tmc2208 Standalone. Please try Marlin RC8. I activated DualZMotor and can now use DualZ Endstops. // A lot faster (4x-10x?) #define Z_DUAL_STEPPER_DRIVERS. See if it's better behaved with this file when using bugfix-1.1.x How do I enable Z1, only one stepper is moving. Don't know what the pulse width is when it's set to zero. pins_RAMPS.h.swapped.zip. - both Z steppers rotate properly, Marlin 1.1.0 - one Z stepper rotates much faster than the other, the other is rotating at the 1.0.? Does that firmware-controlled power supply option that @fiveangle says, is when I use a relay to turn ON/OFF the printer using a Raspberry Pi and octoprint? Description. #define X_DRIVER_TYPE TMC2209 Note that the Z driver (drive 2 on Duet2) has a dual socket wired in series for powering two z motors at once. 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. 3. Unfortunately it means you'll have to translate the config files as names and options have changed between RC8 & 1.1.x. With DualZ Motor control and DualZ Endstops each ZMotor is driven until it reaches its own endstop. Download the dual x-carriage Marlin firmware (see link at top). I'll as SKR arrives... damn a month and a half waiting. Thanks man Marlin 1.0.? If you have an MKS BASE with Heroic HR4982 stepper drivers then you would first set your MOTHERBOARD to BOARD_MKS_BASE_HEROIC. Please open a new issue for related bugs. 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. To set 8x on X and Y axes the command would be M350 X8 Y8. Have a question about this project? I was just looking through the A4988 data sheet and it'll try to recover from an over current event every 20-40uS. 3D printer stepper motors only going one direction and skipping in the other. You must use the M671 command to define the X and Y coordinates of the leadscrews. @Phantom-Code — The reason I ask is because we now have a MOTHERBOARD named BOARD_MKS_BASE_HEROIC that defines the needed micro-stepping pins and proper HIGH/LOW combinations used to set them. Have a question about this project? It's about as easy to hack the hardware, too. @thinkyhead , @Roxy-3D - I'm out of ideas on this one. #define E0_DRIVER_TYPE TMC2209, My single motor dual Z Marlin Configuration_adv.h: I can't figure out why that's happening. @Phantom-Code — Can you tell what kind of stepper drivers are on your board? 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 I will try my best to help out with the configuration. You can also try setting MINIMUM_STEPPER_PULSE to 10. If you have a single nozzle, a switching extruder, a mixing extruder, or dual X carriages, specify that below. We’ll occasionally send you account related emails. After replacing the belts with lead screws I need to pass X Y on 1/4 step. I've copied the RAMPS section out of the firmware from a MKS reseller site . Swapping stepper cables moves the extra speed to the other stepper. Re: RAMPS 1.4 & Marlin driving dual Y steppers.

You signed in with another tab or window. @Phantom-Code — Please share your pins file. If the stepper current is too low then we'd be losing steps, not gaining them. Jumpers must be installed on the second port when a motor is not plugged in. asked Jan 11 '19 at 16:04. @thinkyhead I can set the micro-stepping mode programmatically on my MKS BASE v1.5. Just unplug one & see if the other is spinning at the normal or the fast speed. for marlin 1.1.9 - does this work on MKS Gen L board, setting Z_DUAL_STEPPER_DRIVERS using E1 as Z2? Dual Z Stepper Motor Adapter w/Cable $ 4.99. We’ll occasionally send you account related emails. #define Z2_DRIVER_TYPE TMC2209 // Instead this will fire up the E1 port for your 2nd Z https://www.youtube.com/watch?v=sZuyGD4ciwk, Hi, you are on the right way. ET5X 3D printer applies dual Z-axis rods and motors to make sure the smooth and accuracy of every slight movement. Set Configuration.h like: I'm actually about to compile bugfix and see what I can do about it then do it all over again for my Ender. // For Z set the number of stepper drivers I'm not an electronics engineer, just a programmer. Marlin 1.0.? to your account. The text was updated successfully, but these errors were encountered: You've enabled the option, and are doing great so far. On 1.0.x torque is high enough, I can't block it even with three fingers when it connected to the axis rod. By default Marlin will assume separate nozzles all moving together on a single carriage. See this commit, file pins_MKS_BASE.h. Z axis Stepper motors not working correctly. I'm using dual Z with the TMC2130 on all axis. Swap the cables for the two Z motors AT THE CONTROLLER. @JRosello it should be damn near the same, other than E-Step values I think. Rough Diagram _X_ _Y_ _Z1_ _Null_ _E0_ _Z2_ one of the motors is turning further than the other per demanded distance and the bed goes out of true. If you want use endstops you need to cut the drag pin. @thinkyhead you cut out these pin definitions from the bugfix-1.1.x branch yourself. Look to enable “Z_DUAL_STEPPER_DRIVERS” in Configuration_adv.h in Marlin. Thanks! 1 is the minimum for that chip. Sign in pins_RAMPS.zip. This value should be set to the total number of E stepper motors on the machine, even if there’s only a single nozzle. Add to cart. I glued radiators on top of them so it's pretty hard to see. // For Z set the number of stepper drivers Maybe they should be defined in another file, I don't know. can you tell me how to modify on the program MKS BASE v1.5? Which versions of the MKS BASE board has them and which don't? I didn't read this issue even though you flagged me on it. Already on GitHub? Here's a long shot. I have Allegro driver Does this require 2 z-endstops? [1.1.x] Add BOARD_MKS_BASE_15 with digital micro-stepping, [2.0.x] Add BOARD_MKS_BASE_15 with digital micro-stepping. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. 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. Rough diagram _X_ _Y_ _Z1_ _Z2_ _E0_ _Null_ 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. marlin stepper-driver. Without a doubt, setting the amount of steps a stepper motor needs to move per mm is important for dimensional accuracy. It is likely that one of the Z-Axis is out of level after a while. If you need any help, please let me know. But it would exhibit the same behavior. People using RAMPS with RepRaps, ORD Bots and other 3D printers wire their two Z motors in parallel. I'm planning to upgrade my electronics with a relay to do that... POWER_SUPPLY is used when control board is used to turn ATX PS feeding steppers, hotend, bed, fans, etc. Well, I cant tell about other boards but the MKS BASE v1.5 that I have can control its microstepping pins. Thanks for the update. Align multiple Z stepper motors using a bed probe by probing one position per stepper. If you find that you have HR4982 drivers, then you should set MOTHERBOARD to BOARD_MKS_BASE_HEROIC. Swap the cables for the two Z motors AT THE CONTROLLER. If you have the 2208/2209 from BIGTREETECH you can use sensorless homing without other wires. This instructable is meant for owners of RepRap and other 3d Printers which use 2 stepper motors for the Z axis, as commonly seen in the Prusa or Mendel styles of printers, among many others. Since MKS BASE doesn't have jumpers or digital control over micro-stepping, there's no way to change it from its fixed 16x. You will need to increase the current for the z axis, but not double it. By clicking “Sign up for GitHub”, you agree to our terms of service and Did you transfer your machine specific items to the config files that came with 1.1.0 ? The biggest improvement in this kit are the Trinamic drivers, which make the machine run smoothly and quietly. It's possible. 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. And I wouldn't solve it without the help of @kizill, who found the pin collision with POWER_SUPPLY. He's running dual Z drivers on a MKS Base v1.5 controller and seeing the following: I'm sorry. In that case I guess we'll add MKS_BASE_15 for a board that has digital micro-stepping, but not the HR drivers. The only thing I can think of that the firmware change might have affected is the step pulse width to the controller chips. Technical Support: TH3D Community Support. Has he the same micro-stepping jumpers installed for both stepper drivers (Z and E1)? Do both motors turn in the same direction at the same speed? Using ATX PS on/off via RPi/OP happens upstream of control board so is completely independent of POWER_SUPPLY feature of Marlin. on/off. how to modify microstepping directly in marlin? Only one of the ports can be used for independent motor leveling. Top. When I issue M43 I, there are no extra functions assigned to the Z and the E1/Z2 pins. Post by chris33 » Sat Nov 01, … The board controls both motors as one motor, so you only need to config Z0. I apologize. Before I kick this up to more experienced people, lets see if we can better identify when things went wrong. 4. they are programmed on 1/16. Better idea is the second one on E1. Save your current pins_RAMPS.h file and then drop in one out of the ZIP file. 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 … The over current threshold is dependent on the Vref setting. https://www.youtube.com/watch?v=sZuyGD4ciwk. Also, I can upload ZIP, if it still needed :) // Uncomment this option to use a separate stepper driver for each Z axis motor. May be their engineers modified some settings elsewhere excepting Configuration.h and Configuration_adv.h. works You Could define 2 endstops, however I'd STILL recommend using the BL Touch in this case and using Marlin 2.0.5.3 you can play with this code if you remove the belt (on Sidewinders/Genius's) that connect them to set individual Z-offsets. Does it matter if I change that value to 0? It seems to be driving ok apart from the steps per unit seem to be out. @Bob-the-Kuhn, I'll try your seggestions ASAP. SKR 1.3 with TMC2208 in UART mode on AM8. #if NUM_Z_STEPPER_DRIVERS > 1 A fresh perspective is needed. @webhive I'm glad it helped. None of ours define the micro-stepping CS pins. The text was updated successfully, but these errors were encountered: see this video I just tried Marlin-bugfix-1.1.x from yesterday and my dual Z is working correctly. Press J to jump to the feed. 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). #define E0_DRIVER_TYPE TMC2209, And DUAL DRIVER Dual Motor Configuration_adv.h: #if NUM_Z_STEPPER_DRIVERS > 1 I wonder if this is why there are apparently more steps than should be. 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. hi my 1.7 stepper motors are using 1.7amp which it to much to share 1 stepper driver so im trying to get the seconded motor to run of e1 (extruder motor) so i can use z dual motors on z and e1 now ive been on google for a few days now and ive gottenthese bits changed in … You signed in with another tab or window. I used your configuration files, downloaded it and printed out a list of the pins and the functions assigned to them. Yes, I also was the one who added them in the first place. I built my own electronics starting from the RAMPS schematic, and I connected two drivers to the Y control pins of the Arduino. And if you find that you have non-Heroic stepper drivers, then we will need to add a new board, BOARD_MKS_BASE_15. Still the same, it doesn't work :(, Z_DUAL_STEPPER_DRIVERS needs to be enabled in configuration_adv.h. It's still working via Octoprint and the TFT works however it only sees its internal sdisk atm. 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. I have MKS Base v1.5 with 5 drivers on my Sunhokey Prusa i4 (clone of prusa i3). Two, 2 Z axis motor can be connected to the Z motor 1, Z motor 2, other functions and MKS-Gen is the same. Just got the skr 1.4 turbo and have been pulling my teeth trying to configure it to work with my Ender 5 plus. 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). Hmmm, I'm sorry, but I didn't mentioned yet, that I used Marlin 1.0.0 provided by Sunhokey. #define NUM_Z_STEPPER_DRIVERS 2 // (1-4) Z options change based on how many Line 572-574: For sensorless homing, I have it set to 0 so that it bumps just once when homing. Tried to enable the "#define Z_DUAL_STEPPER_DRIVERS", from which the second motor is operating, but he has mad speed. @Roxy-3D - I'm out of ideas on this one. This issue has been automatically locked since there has not been any recent activity after it was closed. @thinkyhead honestly, I don't remember. i.e. You can connect the second motor to E0 or E1 and modify Marlin. You need only the jumper on MS3. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. #define Z_DRIVER_TYPE TMC2209 // This will STILL send juice to Z2 but don't use if using 2 Drivers But if you want, I'll start digging in and we can bounce ideas back and forth. How to make driver of E1 for motor Z2 on RAMPS 1.4? 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. If you use no UART Mode then you need to set the vref up to the double of the vref for the first motor. The way I read emails and issues caused me to miss this one. Sign in I want to get my NEMA17 on 1/4. And what if I do have an ATX PSU? Bla, Bla, Bla. Line 496: Enable this since we have 2 z stepper motors. speed, Marlin bugfix-1.1.x - same problem as Marlin 1.1.0. 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. #define Y_DRIVER_TYPE TMC2209 Z-Axis doesn't work only during printing.

Successfully merging a pull request may close this issue. Hi Marlin 1.1.? I have enabled #define NUM_Z_STEPPER_DRIVERS 2 and am running all my drivers in UART with jumpers set properly. 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. Press question mark to learn the rest of the keyboard shortcuts A fresh perspective is needed. I've installed them both and updated the firmware and the machine runs great! Tevo were kind enough to send along a dual axis upgrade kit as well as the TMC2208 upgrade kit.

Going back and forth between the extremes a few times is usually enough to clear the corrosion/dirt out. This command can be used to enable one or more steppers (X,Y,Z,E).If no steppers are specified, this command enables all steppers immediately. Whomever was my helpful authority on MKS BASE at the time didn't seem to know about different board versions. Should I open different issue for my case? I realized today that in the video that the one Z motor was running a lot faster with 1.1.x than with 1.0.x. Digging it out would be a challenge. I assume that it will be no difference with this setup between your Sidewinder and the CR10s, right? Add to wishlist Search for: Product categories. This fix work well on my Sunhokey Prusa I4. Just ZIP them up and drop them on your reply. But I don't have any idea how to fix it. Make sure the current limiting trimpot on the X axis pololu (and the second pololu you swapped out with) isn’t set too low. how to modify microstepping directly in marlin? //A single Z stepper driver is usually used to drive 2 stepper motors. to your account. Hi, yes of course! #define X_DRIVER_TYPE TMC2209 If that same combination sets X micro-stepping to 4x (in testing, G1 X... will move farther) then you have non-Heroic drivers. 0scar ♦ 24.7k 6 6 gold badges 38 38 silver badges 103 103 bronze badges. If your config files are up to date then please post them here. I have de same problem. 4. There's not an obvious firmware reason why they'd rotate at different speeds since both step pins are written with the same macro. And the Z2 Endstop are at 'Y_Max' / E1DECT / Pin1.25. So, thank you @kizill! The speed issue follows the channel. When I was investigating my issue, I used the datasheet from the A4982. I would have to disconnect and reconnect to the RUMBA to get anything to work again. The default configuration for most controller electronics such as RAMPS is to have the motors connected in parallel. Marlin will see a single stepper motor. You've definitely got me scratching my head. The Dual Z-Motors is an example of Marlin code where I know the functionality is there but I've never used it or looked at it... (You do remember me saying: Nobody can even know 1/2 the details of the Marlin code base???) With these drivers you can only set 1x, 8x, 16x, or 128x micro-stepping. This is not needed but a cool feature. #define Y_DRIVER_TYPE TMC2209 Can't hurt to set the stepper current to max for a short time to see if that makes a difference. @shawnsm any chance you can share your configs? Alignment of dual Z-axis steppers. share | improve this question | follow | edited Jan 12 '19 at 15:11. The ZIP file contains pins_RAMPS.h files with that done. Besides trying RC8 I'd also like you to try the following with bugfix-1.1.x: Please also see if it's the Z or the E1 channel that's spinning too fast.
