marlin dual z motors

Merge in any Bukobot Configuration.h changes. It's still working via Octoprint and the TFT works however it only sees its internal sdisk atm. And if you find that you have non-Heroic stepper drivers, then we will need to add a new board, BOARD_MKS_BASE_15. Unfortunately it means you'll have to translate the config files as names and options have changed between RC8 & 1.1.x. Hello 4. Ok, hopefully this clarifies a bit more from what I have gotten via "translation" and trial and error regarding dual Z motors. If you want use endstops you need to cut the drag pin. for marlin 1.1.9 - does this work on MKS Gen L board, setting Z_DUAL_STEPPER_DRIVERS using E1 as Z2? #define NUM_Z_STEPPER_DRIVERS 2 // (1-4) Z options change based on how many Sunhokey Prusa i3 axis x, y, z? Dual Z Stepper Motor Adapter w/Cable quantity. I have spare board MKS Base v1.5 and can make more photos at any time (just ask), but don't have motors for experiments, I'll have to use my printer. @shawnsm Thanks!! they are programmed on 1/16. People using RAMPS with RepRaps, ORD Bots and other 3D printers wire their two Z motors in parallel. // Uncomment this option to use a separate stepper driver for each Z axis motor. #define Y_DRIVER_TYPE TMC2209 Top. 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. Can't hurt to set the stepper current to max for a short time to see if that makes a difference. How do I enable Z1, only one stepper is moving. I used your configuration files, downloaded it and printed out a list of the pins and the functions assigned to them. He's running dual Z drivers on a MKS Base v1.5 controller and seeing the following: I'm sorry. User name ShawnM, give me a bit as I said I'm getting the printer up and going as I typed this so it may be a few before I'm able to post. 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. This fix work well on my Sunhokey Prusa I4. 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. Yes, I cooked it from the scratch :) One-by-one, taking care about deprecated parameters. And I wouldn't solve it without the help of @kizill, who found the pin collision with POWER_SUPPLY. how to modify microstepping directly in marlin? Weâll occasionally send you account related emails. If you find that you have HR4982 drivers, then you should set MOTHERBOARD to BOARD_MKS_BASE_HEROIC. Do both motors turn in the same direction at the same speed? I am playing with this on an Artillery Sidewinder X1, with a BL Touch. 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 â¦ Just got the skr 1.4 turbo and have been pulling my teeth trying to configure it to work with my Ender 5 plus. A fresh perspective is needed. Marlin will see a single stepper motor. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Download the dual x-carriage Marlin firmware (see link at top). If the stepper current is too low then we'd be losing steps, not gaining them. Set Configuration.h like: Digging it out would be a challenge. I apologize. Successfully merging a pull request may close this issue. 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???) RAMPS boards have jumpers that can be set up for various amounts of micro-stepping, and some boards have digital control. 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. Please send a photo of how the Z2 motor is attached to the controller. Weâll occasionally send you account related emails. asked Jan 11 '19 at 16:04. Works with the Ender 3, Ender 3 Pro, and CR-20 . Just unplug one & see if the other is spinning at the normal or the fast speed. //#define Z_MULTI_ENDSTOPS Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Swap the cables for the two Z motors AT THE CONTROLLER. Define #define USE_YMAX_PLUG. // For Z set the number of stepper drivers You can connect the second motor to E0 or E1 and modify Marlin. If you have an MKS BASE with Heroic HR4982 stepper drivers then you would first set your MOTHERBOARD to BOARD_MKS_BASE_HEROIC. // The next unused E driver will be assigned to the second Z stepper. 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 can't figure out why that's happening. @code fantÃ´me Yes, I also was the one who added them in the first place. Swap the cables for the two Z motors AT THE CONTROLLER. one of the motors is turning further than the other per demanded distance and the bed goes out of true. Please try Marlin RC8. I glued radiators on top of them so it's pretty hard to see. Rough Diagram _X_ _Y_ _Z1_ _Null_ _E0_ _Z2_ 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. @Phantom-Code Thank you! Usually if the pulse is too narrow then we'd be losing steps. 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. Z motors spin at different speeds in same direction See M422 for Z-Stepper automatic alignment parameter selection. Sign in The biggest improvement in this kit are the Trinamic drivers, which make the machine run smoothly and quietly. Rough diagram _X_ _Y_ _Z1_ _Z2_ _E0_ _Null_ I use tmc2208 Standalone. @webhive I'm glad it helped. to your account. You signed in with another tab or window. By default Marlin will assume separate nozzles all moving together on a single carriage. I wonder if this is why there are apparently more steps than should be. By clicking “Sign up for GitHub”, you agree to our terms of service and bugfix-1.1.x Z motors spin at different speeds in same direction. I have the same problem with Marlin 1.1.0 (branch Â«1.1.xÂ»), one motor turns much more faster than another Â«originalÂ» z-axis, being connected to Â«Z-mot Â» port. 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. I'm doing the same mod on my SWX1 and having some issues. My DUAL DRIVER DUAL Z Motor Configuration.h: When I was investigating my issue, I used the datasheet from the A4982. Maybe the pot has some corrosion/dirt in it. Does it matter if I change that value to 0? I just tried Marlin bugfix-1.1.x (c262ea9) with this configuration. Connect 2 motors on one side of X in series to Z stepper driver and connect 2 other motors in series to E1. The 5160 can work with 60 V & up to 20A so you can say he has no limit. Marlin 1.1.? Z axis Stepper motors not working correctly. I have de same problem. Please open a new issue for related bugs. Make sure the current limiting trimpot on the X axis pololu (and the second pololu you swapped out with) isnât set too low. Also, I can upload ZIP, if it still needed :) Z0 and Z1 appear to run off the same stepper driver, but I can't find any information on how to enable Z1. #define NUM_Z_STEPPER_DRIVERS 1 // (1-4) Z options change based on how many In that case I guess we'll add MKS_BASE_15 for a board that has digital micro-stepping, but not the HR drivers. How to make driver of E1 for motor Z2 on RAMPS 1.4? Maybe they should be defined in another file, I don't know. Z_STEP and E1_STEP have no other functions assigned to those pins. LinuxFerLife LinuxFerLife. 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. A lot faster (4x-10x?) You need only the jumper on MS3. #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. 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? TMC lib is 0.7.1. The skr 1.4 has Z0 and Z1 in addition to E0 and E1. You must use the M671 command to define the X and Y coordinates of the leadscrews. Are they A4982 or are they HR4982? All you need to do is swap the cables pins_RAMPS.zip. Before I kick this up to more experienced people, lets see if we can better identify when things went wrong. Did you transfer your machine specific items to the config files that came with 1.1.0 ? privacy statement. 1 is the minimum for that chip. I want to get my NEMA17 on 1/4. can you tell me how to modify on the program MKS BASE v1.5? The way I read emails and issues caused me to miss this one. After replacing the belts with lead screws I need to pass X Y on 1/4 step. 9. To set 8x on X and Y axes the command would be M350 X8 Y8. Description. Does this require 2 z-endstops? 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've definitely got me scratching my head. 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.

ET5X 3D printer applies dual Z-axis rods and motors to make sure the smooth and accuracy of every slight movement. works If you have a single nozzle, a switching extruder, a mixing extruder, or dual X carriages, specify that below. Z-Axis doesn't work only during printing. Using ATX PS on/off via RPi/OP happens upstream of control board so is completely independent of POWER_SUPPLY feature of Marlin. The driver ICs are soldered to the board. Disconnect the two Z motors from the belts/screws so the motors can turn freely. 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. #define Z_DRIVER_TYPE TMC2209 // This would drive BOTH Z Motors plugged in at Z1 and Z2 Which versions of the MKS BASE board has them and which don't? 0scar â¦ 24.7k 6 6 gold badges 38 38 silver badges 103 103 bronze badges. chris33 Posts: 51 Joined: Sat May 25, 2013 6:36 pm. Better idea is the second one on E1. This issue has been automatically locked since there has not been any recent activity after it was closed. Already on GitHub? The over current threshold is dependent on the Vref setting. how to modify microstepping directly in marlin? It's possible. On 1.0.x torque is high enough, I can't block it even with three fingers when it connected to the axis rod. Well, I cant tell about other boards but the MKS BASE v1.5 that I have can control its microstepping pins. // Alignment of dual Z-axis steppers. If you need any help, please let me know. Hi, yes of course! If that same combination sets X micro-stepping to 4x (in testing, G1 X... will move farther) then you have non-Heroic drivers. Just ZIP them up and drop them on your reply. Press J to jump to the feed. I was just looking through the A4988 data sheet and it'll try to recover from an over current event every 20-40uS. I assume that it will be no difference with this setup between your Sidewinder and the CR10s, right? I have MKS Base v1.5 with 5 drivers on my Sunhokey Prusa i4 (clone of prusa i3). 3D printer stepper motors only going one direction and skipping in the other. @Roxy-3D - I'm out of ideas on this one. to your account. When I issue M43 I, there are no extra functions assigned to the Z and the E1/Z2 pins. Any thoughts? The same hw works very well with Marlin 1.0.0, I've changed firmware several times and ensured that it's software/configuration problem, no stepping motor adjustment needed. When I have more time I'll post my full Marlin configs and pictures here and on Thingyverse. pins_RAMPS.h.swapped.zip. Do both motors turn in the same direction at the same speed? For my part I try to do the opposite. There's not an obvious firmware reason why they'd rotate at different speeds since both step pins are written with the same macro. with little torque. Hmmm, I'm sorry, but I didn't mentioned yet, that I used Marlin 1.0.0 provided by Sunhokey. Hi Jumpers must be installed on the second port when a motor is not plugged in. Re: RAMPS 1.4 & Marlin driving dual Y steppers. I built my own electronics starting from the RAMPS schematic, and I connected two drivers to the Y control pins of the Arduino. You don't have to tell the printer that there are two motors connected. Swapping stepper cables moves the extra speed to the other stepper. A fresh perspective is needed. 4. Whomever was my helpful authority on MKS BASE at the time didn't seem to know about different board versions. The ZIP file contains pins_RAMPS.h files with that done. @Phantom-Code â Please share your pins file. But if you want, I'll start digging in and we can bounce ideas back and forth. If you just dropped in the ones from RC8 and older can get strange results (and a lot of compiler errors). in later versions of Marlin, this changed to NUM_Z_STEPPER_DRIVERS which we would want to set to a value of 2 . If you use no UART Mode then you need to set the vref up to the double of the vref for the first motor. Wasted lot of time until found your solution. #define Y_DRIVER_TYPE TMC2209 Tried to enable the "#define Z_DUAL_STEPPER_DRIVERS", from which the second motor is operating, but he has mad speed. This value should be set to the total number of E stepper motors on the machine, even if thereâs only a single nozzle. SKR 1.3 with TMC2208 in UART mode on AM8. @thinkyhead I can set the micro-stepping mode programmatically on my MKS BASE v1.5. 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. Line 496: Enable this since we have 2 z stepper motors. I've installed them both and updated the firmware and the machine runs great! Increasing Vref might actually be a solution. The text was updated successfully, but these errors were encountered: see this video The only thing I can think of that the firmware change might have affected is the step pulse width to the controller chips. I'd like to jump in here for a second. The speed issue follows the channel. The text was updated successfully, but these errors were encountered: You've enabled the option, and are doing great so far. 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. Press question mark to learn the rest of the keyboard shortcuts Where do I tell Marlin 2.0 that the assigned board has the DRV8825 drivers? If your config files are up to date then please post them here. @Bob-the-Kuhn, I'll try your seggestions ASAP. Sign in I'm using dual Z with the TMC2130 on all axis. @Phantom-Code â 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. I'll as SKR arrives... damn a month and a half waiting. See if it's better behaved with this file when using bugfix-1.1.x I don't need custom values now and use the default ones (16 micro-steps). Going back and forth between the extremes a few times is usually enough to clear the corrosion/dirt out. 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). Warranty & Support Information. You will need to increase the current for the z axis, but not double it. https://www.youtube.com/watch?v=sZuyGD4ciwk. Thanks! (We're only supporting up to MKS BASE 1.4.). 4. privacy statement. Will also have NEO Pixel info and using "extra" pins for fan control as these are things that bugged me... P.S. 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? 1x Z Rod for Motor Side; All-Metal Dual Z bracket with brass nut and 2x M3 Screws NOTE: Brass nut and 2x M3 Screws provided in parts bag (may not be installed in the bracket) Installation Guide Link; PSU Relocation Downloads; Installation Video . 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. Bottom line, if you are using ONE driver for TWO Z Motors then plug Z1 into Z1 and the 2nd motor into Z2. 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). https://www.youtube.com/watch?v=sZuyGD4ciwk, Hi, you are on the right way. @shawnsm any chance you can share your configs? I didn't read this issue even though you flagged me on it. But I don't have any idea how to fix it. We could set the step pulse width to 100uS and see if that fixes it. Rough diagram _X_ _Y_ _Z1_ _Z2_ _E0_ _Null_ //A single Z stepper driver is usually used to drive 2 stepper motors. Marlin 1.0.? Thanks man I have Allegro driver Bottom line, if you are using ONE driver for TWO Z Motors then plug Z1 into Z1 and the 2nd motor into Z2. Bla, Bla, Bla. Not sure if anyone has successfully cracked this but I'm trying to set up a dual Z drive using the E1 port as a Z2 stepper driver. Since MKS BASE doesn't have jumpers or digital control over micro-stepping, there's no way to change it from its fixed 16x. I'm not an electronics engineer, just a programmer. This is not needed but a cool feature. #define Z_DUAL_STEPPER_DRIVERS. 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. See this commit, file pins_MKS_BASE.h. I activated DualZMotor and can now use DualZ Endstops. Note that the Z driver (drive 2 on Duet2) has a dual socket wired in series for powering two z motors at once. Marlin 1.0.? Soâ¦ please help! With DualZ Motor control and DualZ Endstops each ZMotor is driven until it reaches its own endstop. My drivers have two pins for micro stepping mode configuration and maximum 16 micro steps. @Phantom-Code âÂ Can you tell what kind of stepper drivers are on your board? And what if I do have an ATX PSU? With these drivers you can only set 1x, 8x, 16x, or 128x micro-stepping. @thinkyhead I'm pretty sure I have A4982 drivers. The board controls both motors as one motor, so you only need to config Z0. #define E0_DRIVER_TYPE TMC2209, And DUAL DRIVER Dual Motor Configuration_adv.h: It seems to be driving ok apart from the steps per unit seem to be out. i.e. The default configuration for most controller electronics such as RAMPS is to have the motors connected in parallel. 3. Two, 2 Z axis motor can be connected to the Z motor 1, Z motor 2, other functions and MKS-Gen is the same. Tevo were kind enough to send along a dual axis upgrade kit as well as the TMC2208 upgrade kit. It is likely that one of the Z-Axis is out of level after a while. Already on GitHub? None of ours define the micro-stepping CS pins. @thinkyhead , @Roxy-3D - I'm out of ideas on this one. 3. 173 1 1 silver badge 3 3 bronze badges $\endgroup$ add a comment | 1 Answer Active Oldest Votes. Without a doubt, setting the amount of steps a stepper motor needs to move per mm is important for dimensional accuracy. Dual Z Stepper Motor Adapter w/Cable $ 4.99. It doesn't matter if one or more motors are actually connected. Here's a long shot. 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. Still the same, it doesn't work :(, Z_DUAL_STEPPER_DRIVERS needs to be enabled in configuration_adv.h. In my experience printing with a single lead screw on the Z-axis, it works fine with just one. speed, Marlin bugfix-1.1.x - same problem as Marlin 1.1.0. Have a question about this project? But it would exhibit the same behavior. Marlin - Rumba - Dual Z drivers, z movement breaks movement on all axis December 12, 2015 12:50PM Registered: 4 years ago Posts: 7 ...
