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. I have MKS Base v1.5 with 5 drivers on my Sunhokey Prusa i4 (clone of prusa i3). I wonder if this is why there are apparently more steps than should be. This issue has been automatically locked since there has not been any recent activity after it was closed. 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. #define E0_DRIVER_TYPE TMC2209, My single motor dual Z Marlin Configuration_adv.h: Re: RAMPS 1.4 & Marlin driving dual Y steppers. asked Jan 11 '19 at 16:04. This is not needed but a cool feature. Here's a long shot. I just tried Marlin-bugfix-1.1.x from yesterday and my dual Z is working correctly. The board controls both motors as one motor, so you only need to config Z0. On 1.0.x torque is high enough, I can't block it even with three fingers when it connected to the axis rod. 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). with little torque. To set 8x on X and Y axes the command would be M350 X8 Y8. Thanks appswert Was trying to avoid going through the new Marlin firmware, Geeetech must have removed some stuff from the code. #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. Which versions of the MKS BASE board has them and which don't? And if you find that you have non-Heroic stepper drivers, then we will need to add a new board, BOARD_MKS_BASE_15. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. @Phantom-Code âÂ Can you tell what kind of stepper drivers are on your board?

Set Configuration.h like: - 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.? 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. 3. 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. Rough Diagram _X_ _Y_ _Z1_ _Null_ _E0_ _Z2_ marlin stepper-driver. Do both motors turn in the same direction at the same speed? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. I don't need custom values now and use the default ones (16 micro-steps). This fix work well on my Sunhokey Prusa I4. The 5160 can work with 60 V & up to 20A so you can say he has no limit. @shawnsm Thanks!! Hi Since MKS BASE doesn't have jumpers or digital control over micro-stepping, there's no way to change it from its fixed 16x. Rough diagram _X_ _Y_ _Z1_ _Z2_ _E0_ _Null_ Works with the Ender 3, Ender 3 Pro, and CR-20 . See if it's better behaved with this file when using bugfix-1.1.x #define Z_DRIVER_TYPE TMC2209 // This will STILL send juice to Z2 but don't use if using 2 Drivers @JRosello it should be damn near the same, other than E-Step values I think. But I don't have any idea how to fix it. See M422 for Z-Stepper automatic alignment parameter selection. Have a question about this project? 4. SKR 1.3 with TMC2208 in UART mode on AM8. By default Marlin will assume separate nozzles all moving together on a single carriage. Weâll occasionally send you account related emails. Swap the cables for the two Z motors AT THE CONTROLLER. Well, I cant tell about other boards but the MKS BASE v1.5 that I have can control its microstepping pins. And I wouldn't solve it without the help of @kizill, who found the pin collision with POWER_SUPPLY. Z-Axis doesn't work only during printing. LinuxFerLife LinuxFerLife. Thanks! Have a question about this project? // 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. // Bottom line, if you are using ONE driver for TWO Z Motors then plug Z1 into Z1 and the 2nd motor into Z2. I'd like to jump in here for a second. If you want use endstops you need to cut the drag pin. Successfully merging a pull request may close this issue. If the stepper current is too low then we'd be losing steps, not gaining them. Thanks for the update. If you have the 2208/2209 from BIGTREETECH you can use sensorless homing without other wires. But if you want, I'll start digging in and we can bounce ideas back and forth. If you need any help, please let me know. I apologize. privacy statement. 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. @Roxy-3D - I'm out of ideas on this one. 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. Has he the same micro-stepping jumpers installed for both stepper drivers (Z and E1)? 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. #define X_DRIVER_TYPE TMC2209 I built my own electronics starting from the RAMPS schematic, and I connected two drivers to the Y control pins of the Arduino. I will try my best to help out with the configuration. It's about as easy to hack the hardware, too. 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 And what if I do have an ATX PSU? Just got the skr 1.4 turbo and have been pulling my teeth trying to configure it to work with my Ender 5 plus. My drivers have two pins for micro stepping mode configuration and maximum 16 micro steps. When I issue M43 I, there are no extra functions assigned to the Z and the E1/Z2 pins. Connect 2 motors on one side of X in series to Z stepper driver and connect 2 other motors in series to E1. A fresh perspective is needed. RAMPS boards have jumpers that can be set up for various amounts of micro-stepping, and some boards have digital control. The text was updated successfully, but these errors were encountered: see this video Wasted lot of time until found your solution. Where do I tell Marlin 2.0 that the assigned board has the DRV8825 drivers? May be their engineers modified some settings elsewhere excepting Configuration.h and Configuration_adv.h. @Phantom-Code Thank you! Marlin will see a single stepper motor. 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. Press question mark to learn the rest of the keyboard shortcuts Don't know what the pulse width is when it's set to zero. Define #define USE_YMAX_PLUG. #define Z_DRIVER_TYPE TMC2209 // This would drive BOTH Z Motors plugged in at Z1 and Z2 @webhive I'm glad it helped. Top. By clicking “Sign up for GitHub”, you agree to our terms of service and Hmmm, I'm sorry, but I didn't mentioned yet, that I used Marlin 1.0.0 provided by Sunhokey. Marlin 1.0.? I assume that it will be no difference with this setup between your Sidewinder and the CR10s, right? Tevo were kind enough to send along a dual axis upgrade kit as well as the TMC2208 upgrade kit. 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. 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???) 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. share | improve this question | follow | edited Jan 12 '19 at 15:11. Post by chris33 » Sat Nov 01, â¦ //#define Z_MULTI_ENDSTOPS I have enabled #define NUM_Z_STEPPER_DRIVERS 2 and am running all my drivers in UART with jumpers set properly. If you just dropped in the ones from RC8 and older can get strange results (and a lot of compiler errors). Just ZIP them up and drop them on your reply. works speed, Marlin bugfix-1.1.x - same problem as Marlin 1.1.0. Add to cart. 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. Please try Marlin RC8. Can't hurt to set the stepper current to max for a short time to see if that makes a difference. 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 . You need only the jumper on MS3. Whomever was my helpful authority on MKS BASE at the time didn't seem to know about different board versions. For my part I try to do the opposite. in later versions of Marlin, this changed to NUM_Z_STEPPER_DRIVERS which we would want to set to a value of 2 . People using RAMPS with RepRaps, ORD Bots and other 3D printers wire their two Z motors in parallel. #define Y_DRIVER_TYPE TMC2209 You've definitely got me scratching my head. And the Z2 Endstop are at 'Y_Max' / E1DECT / Pin1.25. 4. Using ATX PS on/off via RPi/OP happens upstream of control board so is completely independent of POWER_SUPPLY feature of Marlin. Weâll occasionally send you account related emails. Better idea is the second one on E1. Download the dual x-carriage Marlin firmware (see link at top). I have de same problem. Description. #define NUM_Z_STEPPER_DRIVERS 2 // (1-4) Z options change based on how many Align multiple Z stepper motors using a bed probe by probing one position per stepper. they are programmed on 1/16. 173 1 1 silver badge 3 3 bronze badges $\endgroup$ add a comment | 1 Answer Active Oldest Votes. // For Z set the number of stepper drivers In my experience printing with a single lead screw on the Z-axis, it works fine with just one. Successfully merging a pull request may close this issue. 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. With DualZ Motor control and DualZ Endstops each ZMotor is driven until it reaches its own endstop. I want to get my NEMA17 on 1/4. We discussed micro-stepping pins for MKS BASE 1.5 earlier in this thread and I was able to change them programmatically before I solved my issue. 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? Maybe the pot has some corrosion/dirt in it. He's running dual Z drivers on a MKS Base v1.5 controller and seeing the following: I'm sorry. So, thank you @kizill! None of ours define the micro-stepping CS pins. 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. Z0 and Z1 appear to run off the same stepper driver, but I can't find any information on how to enable Z1. The skr 1.4 has Z0 and Z1 in addition to E0 and E1. // The next unused E driver will be assigned to the second Z stepper. 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. If your config files are up to date then please post them here. Swapping stepper cables moves the extra speed to the other stepper. The driver ICs are soldered to the board. Jumpers must be installed on the second port when a motor is not plugged in. A lot faster (4x-10x?) TMC lib is 0.7.1. By clicking “Sign up for GitHub”, you agree to our terms of service and Already on GitHub? Hi, yes of course! Maybe they should be defined in another file, I don't know. Already on GitHub? I glued radiators on top of them so it's pretty hard to see. You can connect the second motor to E0 or E1 and modify Marlin. The speed issue follows the channel. #define Y_DRIVER_TYPE TMC2209 Press J to jump to the feed. // Uncomment this option to use a separate stepper driver for each Z axis motor. We could set the step pulse width to 100uS and see if that fixes it. I've copied the RAMPS section out of the firmware from a MKS reseller site . Going back and forth between the extremes a few times is usually enough to clear the corrosion/dirt out. // For Z set the number of stepper drivers Sign in But it would exhibit the same behavior. how to modify microstepping directly in marlin? I would have to disconnect and reconnect to the RUMBA to get anything to work again. Soâ¦ please help! I can't figure out why that's happening. Digging it out would be a challenge. Z motors spin at different speeds in same direction Merge in any Bukobot Configuration.h changes. A fresh perspective is needed. privacy statement. The biggest improvement in this kit are the Trinamic drivers, which make the machine run smoothly and quietly. Will also have NEO Pixel info and using "extra" pins for fan control as these are things that bugged me... P.S. @thinkyhead you cut out these pin definitions from the bugfix-1.1.x branch yourself. The way I read emails and issues caused me to miss this one. 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). After replacing the belts with lead screws I need to pass X Y on 1/4 step. Warranty & Support Information. ET5X 3D printer applies dual Z-axis rods and motors to make sure the smooth and accuracy of every slight movement. You must use the M671 command to define the X and Y coordinates of the leadscrews. My DUAL DRIVER DUAL Z Motor Configuration.h: 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. 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. Are they A4982 or are they HR4982? It is likely that one of the Z-Axis is out of level after a while. Only one of the ports can be used for independent motor leveling. 1 is the minimum for that chip. Please send a photo of how the Z2 motor is attached to the controller. There's not an obvious firmware reason why they'd rotate at different speeds since both step pins are written with the same macro. Note that the Z driver (drive 2 on Duet2) has a dual socket wired in series for powering two z motors at once. You signed in with another tab or window. Hello I use tmc2208 Standalone. 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. Disconnect the two Z motors from the belts/screws so the motors can turn freely. Yes, I cooked it from the scratch :) One-by-one, taking care about deprecated parameters. If you find that you have HR4982 drivers, then you should set MOTHERBOARD to BOARD_MKS_BASE_HEROIC. https://www.youtube.com/watch?v=sZuyGD4ciwk, Hi, you are on the right way. I'm using dual Z with the TMC2130 on all axis. 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. If you use no UART Mode then you need to set the vref up to the double of the vref for the first motor. Sign in @thinkyhead I'm pretty sure I have A4982 drivers. I activated DualZMotor and can now use DualZ Endstops. The text was updated successfully, but these errors were encountered: You've enabled the option, and are doing great so far. All you need to do is swap the cables Also, I can upload ZIP, if it still needed :) Bla, Bla, Bla. Z axis Stepper motors not working correctly. If that same combination sets X micro-stepping to 4x (in testing, G1 X... will move farther) then you have non-Heroic drivers. bugfix-1.1.x Z motors spin at different speeds in same direction. #define NUM_Z_STEPPER_DRIVERS 1 // (1-4) Z options change based on how many 3D printer stepper motors only going one direction and skipping in the other. 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. I'll as SKR arrives... damn a month and a half waiting. Swap the cables for the two Z motors AT THE CONTROLLER. Thanks man Dual Z Stepper Motor Adapter w/Cable $ 4.99. With these drivers you can only set 1x, 8x, 16x, or 128x micro-stepping. It seems to be driving ok apart from the steps per unit seem to be out. 0scar â¦ 24.7k 6 6 gold badges 38 38 silver badges 103 103 bronze badges. Do both motors turn in the same direction at the same speed? 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 â¦ The only thing I can think of that the firmware change might have affected is the step pulse width to the controller chips. It can get a high printing speed and higher printing precision. chris33 Posts: 51 Joined: Sat May 25, 2013 6:36 pm. Look to enable âZ_DUAL_STEPPER_DRIVERSâ in Configuration_adv.h in Marlin. #define Z_DUAL_STEPPER_DRIVERS. pins_RAMPS.h.swapped.zip. Alignment of dual Z-axis steppers. See this commit, file pins_MKS_BASE.h. I used your configuration files, downloaded it and printed out a list of the pins and the functions assigned to them. for marlin 1.1.9 - does this work on MKS Gen L board, setting Z_DUAL_STEPPER_DRIVERS using E1 as Z2? #if NUM_Z_STEPPER_DRIVERS > 1 When I have more time I'll post my full Marlin configs and pictures here and on Thingyverse. Unfortunately it means you'll have to translate the config files as names and options have changed between RC8 & 1.1.x. how to modify microstepping directly in marlin? Rough diagram _X_ _Y_ _Z1_ _Z2_ _E0_ _Null_ I just tried Marlin bugfix-1.1.x (c262ea9) with this configuration. The default configuration for most controller electronics such as RAMPS is to have the motors connected in parallel. 3. @shawnsm any chance you can share your configs? 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¦ I've installed them both and updated the firmware and the machine runs great! Z_STEP and E1_STEP have no other functions assigned to those pins. When I was investigating my issue, I used the datasheet from the A4982. In that case I guess we'll add MKS_BASE_15 for a board that has digital micro-stepping, but not the HR drivers. @thinkyhead , @Roxy-3D - I'm out of ideas on this one. The over current threshold is dependent on the Vref setting. Tried to enable the "#define Z_DUAL_STEPPER_DRIVERS", from which the second motor is operating, but he has mad speed. Should I open different issue for my case? Ok, hopefully this clarifies a bit more from what I have gotten via "translation" and trial and error regarding dual Z motors. 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. How do I enable Z1, only one stepper is moving. Sunhokey Prusa i3 axis x, y, z? Before I kick this up to more experienced people, lets see if we can better identify when things went wrong. https://www.youtube.com/watch?v=sZuyGD4ciwk. Just unplug one & see if the other is spinning at the normal or the fast speed. You Could define 2 endstops, however I'd STILL recommend using the BL Touch in this case and using Marlin 126.96.36.199 you can play with this code if you remove the belt (on Sidewinders/Genius's) that connect them to set individual Z-offsets. I'm doing the same mod on my SWX1 and having some issues. 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. Dual Z Stepper Motor Adapter w/Cable quantity. Usually if the pulse is too narrow then we'd be losing steps. Did you transfer your machine specific items to the config files that came with 1.1.0 ? 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. Instead of messing with regular endstops I chose to use Z-Min as the BLTouch Probe pin for my Z Probe and End Stop. You can also try setting MINIMUM_STEPPER_PULSE to 10. @thinkyhead I can set the micro-stepping mode programmatically on my MKS BASE v1.5. 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. to your account. [1.1.x] Add BOARD_MKS_BASE_15 with digital micro-stepping, [2.0.x] Add BOARD_MKS_BASE_15 with digital micro-stepping. 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. @Bob-the-Kuhn, I'll try your seggestions ASAP. Yes, I also was the one who added them in the first place. on/off. I'm actually about to compile bugfix and see what I can do about it then do it all over again for my Ender. @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. Save your current pins_RAMPS.h file and then drop in one out of the ZIP file. You will need to increase the current for the z axis, but not double it. It's still working via Octoprint and the TFT works however it only sees its internal sdisk atm. Marlin 1.1.? The ZIP file contains pins_RAMPS.h files with that done. I didn't read this issue even though you flagged me on it.

Increasing Vref might actually be a solution. It doesn't matter if one or more motors are actually connected. I'm not an electronics engineer, just a programmer. Without a doubt, setting the amount of steps a stepper motor needs to move per mm is important for dimensional accuracy. Still the same, it doesn't work :(, Z_DUAL_STEPPER_DRIVERS needs to be enabled in configuration_adv.h. can you tell me how to modify on the program MKS BASE v1.5? I was just looking through the A4988 data sheet and it'll try to recover from an over current event every 20-40uS.
