Unfortunately it means you'll have to translate the config files as names and options have changed between RC8 & 1.1.x. //#define Z_MULTI_ENDSTOPS If you have a single nozzle, a switching extruder, a mixing extruder, or dual X carriages, specify that below. 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). Has he the same micro-stepping jumpers installed for both stepper drivers (Z and E1)? https://www.youtube.com/watch?v=sZuyGD4ciwk. Just ZIP them up and drop them on your reply. Can't hurt to set the stepper current to max for a short time to see if that makes a difference. I have the same problem with Marlin 1.1.0 (branch «1.1.x»), one motor turns much more faster than another «original» z-axis, being connected to «Z-mot » port. The speed issue follows the channel. You can connect the second motor to E0 or E1 and modify Marlin. The ZIP file contains pins_RAMPS.h files with that done. Do both motors turn in the same direction at the same speed? Tevo were kind enough to send along a dual axis upgrade kit as well as the TMC2208 upgrade kit. 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 … Do both motors turn in the same direction at the same speed? With these drivers you can only set 1x, 8x, 16x, or 128x 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. Tried to enable the "#define Z_DUAL_STEPPER_DRIVERS", from which the second motor is operating, but he has mad speed. I glued radiators on top of them so it's pretty hard to see. Which versions of the MKS BASE board has them and which don't? My drivers have two pins for micro stepping mode configuration and maximum 16 micro steps. on/off. And if you find that you have non-Heroic stepper drivers, then we will need to add a new board, BOARD_MKS_BASE_15. (We're only supporting up to MKS BASE 1.4.). 3D printer stepper motors only going one direction and skipping in the other. 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. Z0 and Z1 appear to run off the same stepper driver, but I can't find any information on how to enable Z1. Define #define USE_YMAX_PLUG. can you tell me how to modify on the program MKS BASE v1.5? Only one of the ports can be used for independent motor leveling. For my part I try to do the opposite. Thanks man 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 how to modify microstepping directly in marlin? After replacing the belts with lead screws I need to pass X Y on 1/4 step. I activated DualZMotor and can now use DualZ Endstops. Does this require 2 z-endstops? pins_RAMPS.zip. 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. I'll as SKR arrives... damn a month and a half waiting. If you want use endstops you need to cut the drag pin. #define Z_DRIVER_TYPE TMC2209 // This would drive BOTH Z Motors plugged in at Z1 and Z2 // 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. When I issue M43 I, there are no extra functions assigned to the Z and the E1/Z2 pins. @code fantôme I'm actually about to compile bugfix and see what I can do about it then do it all over again for my Ender. We’ll occasionally send you account related emails. @shawnsm Thanks!! Set Configuration.h like: Merge in any Bukobot Configuration.h changes. If that same combination sets X micro-stepping to 4x (in testing, G1 X... will move farther) then you have non-Heroic drivers. @thinkyhead honestly, I don't remember. Z_STEP and E1_STEP have no other functions assigned to those pins. Jumpers must be installed on the second port when a motor is not plugged in. #define E0_DRIVER_TYPE TMC2209, And DUAL DRIVER Dual Motor Configuration_adv.h: A lot faster (4x-10x?) 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. #if NUM_Z_STEPPER_DRIVERS > 1 Hello Successfully merging a pull request may close this issue. asked Jan 11 '19 at 16:04. 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.? Does it matter if I change that value to 0? Hi Ok, hopefully this clarifies a bit more from what I have gotten via "translation" and trial and error regarding dual Z motors. Marlin firmware 1.0.x by Sunhokey. #define Z_DUAL_STEPPER_DRIVERS. I'd like to jump in here for a second. 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 . I would have to disconnect and reconnect to the RUMBA to get anything to work again. // For Z set the number of stepper drivers I wonder if this is why there are apparently more steps than should be. Bottom line, if you are using ONE driver for TWO Z Motors then plug Z1 into Z1 and the 2nd motor into Z2. In my experience printing with a single lead screw on the Z-axis, it works fine with just one. See M422 for Z-Stepper automatic alignment parameter selection. Rough diagram _X_ _Y_ _Z1_ _Z2_ _E0_ _Null_ 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. 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???) pins_RAMPS.h.swapped.zip. I was just looking through the A4988 data sheet and it'll try to recover from an over current event every 20-40uS. - 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.? Z-Axis doesn't work only during printing. The driver ICs are soldered to the board. I have MKS Base v1.5 with 5 drivers on my Sunhokey Prusa i4 (clone of prusa i3). So… please help! It can get a high printing speed and higher printing precision. 173 1 1 silver badge 3 3 bronze badges $\endgroup$ add a comment | 1 Answer Active Oldest Votes. 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. There's not an obvious firmware reason why they'd rotate at different speeds since both step pins are written with the same macro. 3. Sign in I want to get my NEMA17 on 1/4. I use tmc2208 Standalone. 4. @webhive I'm glad it helped. i.e. I'm not an electronics engineer, just a programmer. they are programmed on 1/16. It's about as easy to hack the hardware, too. @Phantom-Code Thank you! SKR 1.3 with TMC2208 in UART mode on AM8. But I don't have any idea how to fix it. I have enabled #define NUM_Z_STEPPER_DRIVERS 2 and am running all my drivers in UART with jumpers set properly. I didn't read this issue even though you flagged me on it. 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. The biggest improvement in this kit are the Trinamic drivers, which make the machine run smoothly and quietly. My DUAL DRIVER DUAL Z Motor Configuration.h: 1 is the minimum for that chip. Line 496: Enable this since we have 2 z stepper motors. The board controls both motors as one motor, so you only need to config Z0. 9. Save your current pins_RAMPS.h file and then drop in one out of the ZIP file. The skr 1.4 has Z0 and Z1 in addition to E0 and E1. in later versions of Marlin, this changed to NUM_Z_STEPPER_DRIVERS which we would want to set to a value of 2 . Should I open different issue for my case? I have de same problem. The way I read emails and issues caused me to miss this one. May be their engineers modified some settings elsewhere excepting Configuration.h and Configuration_adv.h. You signed in with another tab or window. Wasted lot of time until found your solution. privacy statement. Already on GitHub? Thanks!

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. Did you transfer your machine specific items to the config files that came with 1.1.0 ? Maybe they should be defined in another file, I don't know. Please try Marlin RC8. Align multiple Z stepper motors using a bed probe by probing one position per stepper. // For Z set the number of stepper drivers Have a question about this project? How do I enable Z1, only one stepper is moving. Two, 2 Z axis motor can be connected to the Z motor 1, Z motor 2, other functions and MKS-Gen is the same. Warranty & Support Information. Just unplug one & see if the other is spinning at the normal or the fast speed. 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.

RAMPS boards have jumpers that can be set up for various amounts of micro-stepping, and some boards have digital control. Going back and forth between the extremes a few times is usually enough to clear the corrosion/dirt out. Where do I tell Marlin 2.0 that the assigned board has the DRV8825 drivers? @shawnsm any chance you can share your configs? If you have an MKS BASE with Heroic HR4982 stepper drivers then you would first set your MOTHERBOARD to BOARD_MKS_BASE_HEROIC. speed, Marlin bugfix-1.1.x - same problem as Marlin 1.1.0. I'm doing the same mod on my SWX1 and having some issues. 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. If your config files are up to date then please post them here. This value should be set to the total number of E stepper motors on the machine, even if there’s only a single nozzle. All you need to do is swap the cables But if you want, I'll start digging in and we can bounce ideas back and forth. Sign in By clicking “Sign up for GitHub”, you agree to our terms of service and 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. 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. 4. 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. 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. A fresh perspective is needed. And the Z2 Endstop are at 'Y_Max' / E1DECT / Pin1.25. With DualZ Motor control and DualZ Endstops each ZMotor is driven until it reaches its own endstop. By default Marlin will assume separate nozzles all moving together on a single carriage. #define E0_DRIVER_TYPE TMC2209, My single motor dual Z Marlin Configuration_adv.h: 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. The second 'Z2' Motor must plug to the E1 Port and UART make after your changes all needed things. 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? So, thank you @kizill! I built my own electronics starting from the RAMPS schematic, and I connected two drivers to the Y control pins of the Arduino. It's possible. for marlin 1.1.9 - does this work on MKS Gen L board, setting Z_DUAL_STEPPER_DRIVERS using E1 as Z2? Yes, I also was the one who added them in the first place. Here's a long shot. Have a question about this project? Yes, I cooked it from the scratch :) One-by-one, taking care about deprecated parameters. #define Y_DRIVER_TYPE TMC2209 Add to cart. Connect 2 motors on one side of X in series to Z stepper driver and connect 2 other motors in series to E1. 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 am playing with this on an Artillery Sidewinder X1, with a BL Touch. Do both motors turn in the same direction at the same speed? Maybe the pot has some corrosion/dirt in it. Dual Z Stepper Motor Adapter w/Cable $ 4.99. You signed in with another tab or window. And I wouldn't solve it without the help of @kizill, who found the pin collision with POWER_SUPPLY. If the stepper current is too low then we'd be losing steps, not gaining them. Any thoughts? I will try my best to help out with the configuration. Dual Z Stepper Motor Adapter w/Cable quantity. @Phantom-Code — Can you tell what kind of stepper drivers are on your board? Before I kick this up to more experienced people, lets see if we can better identify when things went wrong. Alignment of dual Z-axis steppers. I apologize. privacy statement. Top. @thinkyhead I'm pretty sure I have A4982 drivers.

It's still working via Octoprint and the TFT works however it only sees its internal sdisk atm. @Phantom-Code — Please share your pins file. Thanks appswert Was trying to avoid going through the new Marlin firmware, Geeetech must have removed some stuff from the code. Instead of messing with regular endstops I chose to use Z-Min as the BLTouch Probe pin for my Z Probe and End Stop. 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've copied the RAMPS section out of the firmware from a MKS reseller site . 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 … Are they A4982 or are they HR4982? 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.

Z Axis getting stuck with Marlin 1.1.0-RC7. Increasing Vref might actually be a solution. People using RAMPS with RepRaps, ORD Bots and other 3D printers wire their two Z motors in parallel. Well, I cant tell about other boards but the MKS BASE v1.5 that I have can control its microstepping pins. 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. 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. // Uncomment this option to use a separate stepper driver for each Z axis motor. Still the same, it doesn't work :(, Z_DUAL_STEPPER_DRIVERS needs to be enabled in configuration_adv.h. @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. @thinkyhead , @Roxy-3D - I'm out of ideas on this one. I used your configuration files, downloaded it and printed out a list of the pins and the functions assigned to them. Bla, Bla, Bla. Add to wishlist Search for: Product categories. The text was updated successfully, but these errors were encountered: see this video 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. If you find that you have HR4982 drivers, then you should set MOTHERBOARD to BOARD_MKS_BASE_HEROIC. The default configuration for most controller electronics such as RAMPS is to have the motors connected in parallel. You need only the jumper on MS3. I can't figure out why that's happening. share | improve this question | follow | edited Jan 12 '19 at 15:11. This issue has been automatically locked since there has not been any recent activity after it was closed. But it would exhibit the same behavior. Sunhokey Prusa i3 axis x, y, z? To set 8x on X and Y axes the command would be M350 X8 Y8. to your account. @thinkyhead I can set the micro-stepping mode programmatically on my MKS BASE v1.5. See if it's better behaved with this file when using bugfix-1.1.x Just got the skr 1.4 turbo and have been pulling my teeth trying to configure it to work with my Ender 5 plus. Usually if the pulse is too narrow then we'd be losing steps. to your account. Without a doubt, setting the amount of steps a stepper motor needs to move per mm is important for dimensional accuracy. chris33 Posts: 51 Joined: Sat May 25, 2013 6:36 pm. 3. Re: RAMPS 1.4 & Marlin driving dual Y steppers. I've installed them both and updated the firmware and the machine runs great! Whomever was my helpful authority on MKS BASE at the time didn't seem to know about different board versions. If you use no UART Mode then you need to set the vref up to the double of the vref for the first motor. Already on GitHub? @Bob-the-Kuhn, I'll try your seggestions ASAP. Description. 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. @JRosello it should be damn near the same, other than E-Step values I think. with little torque. how to modify microstepping directly in marlin? 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. I'm using dual Z with the TMC2130 on all axis. Swap the cables for the two Z motors AT THE CONTROLLER. Z axis Stepper motors not working correctly. Please send a photo of how the Z2 motor is attached to the controller. We’ll occasionally send you account related emails. Marlin will see a single stepper motor. 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 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. I assume that it will be no difference with this setup between your Sidewinder and the CR10s, right? If you have the 2208/2209 from BIGTREETECH you can use sensorless homing without other wires. 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? #if NUM_Z_STEPPER_DRIVERS > 1 I just tried Marlin bugfix-1.1.x (c262ea9) with this configuration. If you just dropped in the ones from RC8 and older can get strange results (and a lot of compiler errors). I don't need custom values now and use the default ones (16 micro-steps). Download the dual x-carriage Marlin firmware (see link at top). // The next unused E driver will be assigned to the second Z stepper. The only thing I can think of that the firmware change might have affected is the step pulse width to the controller chips. I just tried Marlin-bugfix-1.1.x from yesterday and my dual Z is working correctly. Using ATX PS on/off via RPi/OP happens upstream of control board so is completely independent of POWER_SUPPLY feature of Marlin. Marlin 1.0.? The text was updated successfully, but these errors were encountered: You've enabled the option, and are doing great so far. @thinkyhead you cut out these pin definitions from the bugfix-1.1.x branch yourself. Swap the cables for the two Z motors AT THE CONTROLLER. #define NUM_Z_STEPPER_DRIVERS 2 // (1-4) Z options change based on how many Disconnect the two Z motors from the belts/screws so the motors can turn freely.

ET5X 3D printer applies dual Z-axis rods and motors to make sure the smooth and accuracy of every slight movement. You've definitely got me scratching my head. 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. A fresh perspective is needed. Make sure the current limiting trimpot on the X axis pololu (and the second pololu you swapped out with) isn’t set too low. See this commit, file pins_MKS_BASE.h. In that case I guess we'll add MKS_BASE_15 for a board that has digital micro-stepping, but not the HR drivers. You can also try setting MINIMUM_STEPPER_PULSE to 10. The over current threshold is dependent on the Vref setting. 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. https://www.youtube.com/watch?v=sZuyGD4ciwk, Hi, you are on the right way. You will need to increase the current for the z axis, but not double it. Successfully merging a pull request may close this issue. 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). Swapping stepper cables moves the extra speed to the other stepper. Digging it out would be a challenge. LinuxFerLife LinuxFerLife. Technical Support: TH3D Community Support. How to make driver of E1 for motor Z2 on RAMPS 1.4? Hmmm, I'm sorry, but I didn't mentioned yet, that I used Marlin 1.0.0 provided by Sunhokey.
