Any thoughts? Rough diagram _X_ _Y_ _Z1_ _Z2_ _E0_ _Null_ Will also have NEO Pixel info and using "extra" pins for fan control as these are things that bugged me... P.S. they are programmed on 1/16. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. ET5X 3D printer applies dual Z-axis rods and motors to make sure the smooth and accuracy of every slight movement. 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. How do I enable Z1, only one stepper is moving. on/off. pins_RAMPS.zip. RAMPS boards have jumpers that can be set up for various amounts of micro-stepping, and some boards have digital control. Did you transfer your machine specific items to the config files that came with 1.1.0 ? 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. It can get a high printing speed and higher printing precision. 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. But I don't have any idea how to fix it. @webhive I'm glad it helped. May be their engineers modified some settings elsewhere excepting Configuration.h and Configuration_adv.h. I have MKS Base v1.5 with 5 drivers on my Sunhokey Prusa i4 (clone of prusa i3). We’ll occasionally send you account related emails. You will need to increase the current for the z axis, but not double it. // Uncomment this option to use a separate stepper driver for each Z axis motor. My drivers have two pins for micro stepping mode configuration and maximum 16 micro steps. I apologize. With DualZ Motor control and DualZ Endstops each ZMotor is driven until it reaches its own endstop. 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 NUM_Z_STEPPER_DRIVERS 1 // (1-4) Z options change based on how many I was just looking through the A4988 data sheet and it'll try to recover from an over current event every 20-40uS. If you use no UART Mode then you need to set the vref up to the double of the vref for the first motor. with little torque. @thinkyhead I'm pretty sure I have A4982 drivers. I'm using dual Z with the TMC2130 on all axis. Already on GitHub? A fresh perspective is needed. If you have a single nozzle, a switching extruder, a mixing extruder, or dual X carriages, specify that below. A fresh perspective is needed. Only one of the ports can be used for independent motor leveling. #define Y_DRIVER_TYPE TMC2209 I have Allegro driver In my experience printing with a single lead screw on the Z-axis, it works fine with just one. We’ll occasionally send you account related emails. You've definitely got me scratching my head. By clicking “Sign up for GitHub”, you agree to our terms of service and I'm actually about to compile bugfix and see what I can do about it then do it all over again for my Ender. I've installed them both and updated the firmware and the machine runs great! Post by chris33 » Sat Nov 01, … I am playing with this on an Artillery Sidewinder X1, with a BL Touch. There's not an obvious firmware reason why they'd rotate at different speeds since both step pins are written with the same macro. @code fantôme When I have more time I'll post my full Marlin configs and pictures here and on Thingyverse. Hi Top. Increasing Vref might actually be a solution. Where do I tell Marlin 2.0 that the assigned board has the DRV8825 drivers? Successfully merging a pull request may close this issue. Usually if the pulse is too narrow then we'd be losing steps. People using RAMPS with RepRaps, ORD Bots and other 3D printers wire their two Z motors in parallel. We could set the step pulse width to 100uS and see if that fixes it. Using ATX PS on/off via RPi/OP happens upstream of control board so is completely independent of POWER_SUPPLY feature of Marlin. Marlin will see a single stepper motor. Technical Support: TH3D Community Support. You need only the jumper on MS3. #if NUM_Z_STEPPER_DRIVERS > 1 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. Z axis Stepper motors not working correctly. how to modify microstepping directly in marlin? Add to cart. I just tried Marlin bugfix-1.1.x (c262ea9) with this configuration. It's still working via Octoprint and the TFT works however it only sees its internal sdisk atm. Just ZIP them up and drop them on your reply. Should I open different issue for my case? Marlin 1.1.? And the Z2 Endstop are at 'Y_Max' / E1DECT / Pin1.25. //A single Z stepper driver is usually used to drive 2 stepper motors. 3. 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? 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. Swapping stepper cables moves the extra speed to the other stepper. Already on GitHub? privacy statement. After replacing the belts with lead screws I need to pass X Y on 1/4 step. SKR 1.3 with TMC2208 in UART mode on AM8. And what if I do have an ATX PSU? If you find that you have HR4982 drivers, then you should set MOTHERBOARD to BOARD_MKS_BASE_HEROIC. Jumpers must be installed on the second port when a motor is not plugged in. The way I read emails and issues caused me to miss this one. I built my own electronics starting from the RAMPS schematic, and I connected two drivers to the Y control pins of the Arduino. Have a question about this project? I assume that it will be no difference with this setup between your Sidewinder and the CR10s, right? All Products (141) 3D Printer Boards & Addons (9) Auto Bed Leveling Kits (4) Build Sheets/Flex Systems (6) Cables (9) Dual Extrusion Parts (7) eBooks/Books (2) Extruders (6) EZABL/ABL Accessories (8) EZOut Kits/Packages (11) Fans (10) … This value should be set to the total number of E stepper motors on the machine, even if there’s only a single nozzle. Re: RAMPS 1.4 & Marlin driving dual Y steppers. Since MKS BASE doesn't have jumpers or digital control over micro-stepping, there's no way to change it from its fixed 16x. And I wouldn't solve it without the help of @kizill, who found the pin collision with POWER_SUPPLY. Note that the Z driver (drive 2 on Duet2) has a dual socket wired in series for powering two z motors at once. 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. Disconnect the two Z motors from the belts/screws so the motors can turn freely. I use tmc2208 Standalone. I will try my best to help out with the configuration. You signed in with another tab or window. To set 8x on X and Y axes the command would be M350 X8 Y8. 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. My DUAL DRIVER DUAL Z Motor Configuration.h: A lot faster (4x-10x?) 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 … 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. 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. I didn't read this issue even though you flagged me on it. Maybe the pot has some corrosion/dirt in it. Marlin 1.0.? Do both motors turn in the same direction at the same speed? https://www.youtube.com/watch?v=sZuyGD4ciwk, Hi, you are on the right way. I used your configuration files, downloaded it and printed out a list of the pins and the functions assigned to them. 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. - 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.? one of the motors is turning further than the other per demanded distance and the bed goes out of true. Are they A4982 or are they HR4982? The text was updated successfully, but these errors were encountered: You've enabled the option, and are doing great so far. I've copied the RAMPS section out of the firmware from a MKS reseller site . Description. This is not needed but a cool feature. 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. Tried to enable the "#define Z_DUAL_STEPPER_DRIVERS", from which the second motor is operating, but he has mad speed. 4. Thanks appswert Was trying to avoid going through the new Marlin firmware, Geeetech must have removed some stuff from the code. can you tell me how to modify on the program MKS BASE v1.5? When I was investigating my issue, I used the datasheet from the A4982. Whomever was my helpful authority on MKS BASE at the time didn't seem to know about different board versions. Make sure the current limiting trimpot on the X axis pololu (and the second pololu you swapped out with) isn’t set too low. 1 is the minimum for that chip. Have a question about this project? 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. 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). Yes, I cooked it from the scratch :) One-by-one, taking care about deprecated parameters. You don't have to tell the printer that there are two motors connected. Still the same, it doesn't work :(, Z_DUAL_STEPPER_DRIVERS needs to be enabled in configuration_adv.h. Also, I can upload ZIP, if it still needed :) If you need any help, please let me know. 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. Press question mark to learn the rest of the keyboard shortcuts //#define Z_MULTI_ENDSTOPS speed, Marlin bugfix-1.1.x - same problem as Marlin 1.1.0. @thinkyhead honestly, I don't remember. Two, 2 Z axis motor can be connected to the Z motor 1, Z motor 2, other functions and MKS-Gen is the same. 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. Sunhokey Prusa i3 axis x, y, z? 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. You must use the M671 command to define the X and Y coordinates of the leadscrews. 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. Hi, yes of course! So… please help! The driver ICs are soldered to the board. Z-Axis doesn't work only during printing. But it would exhibit the same behavior. Do both motors turn in the same direction at the same speed? #if NUM_Z_STEPPER_DRIVERS > 1 I activated DualZMotor and can now use DualZ Endstops. to your account. Z motors spin at different speeds in same direction I'll as SKR arrives... damn a month and a half waiting. It is likely that one of the Z-Axis is out of level after a while. @Phantom-Code Thank you! Press J to jump to the feed. Marlin 1.0.? I wonder if this is why there are apparently more steps than should be. When I issue M43 I, there are no extra functions assigned to the Z and the E1/Z2 pins. 4. asked Jan 11 '19 at 16:04. @Phantom-Code — Please share your pins file. By default Marlin will assume separate nozzles all moving together on a single carriage. Does it matter if I change that value to 0? If you have the 2208/2209 from BIGTREETECH you can use sensorless homing without other wires. On 1.0.x torque is high enough, I can't block it even with three fingers when it connected to the axis rod. 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. Here's a long shot. You can connect the second motor to E0 or E1 and modify Marlin. By clicking “Sign up for GitHub”, you agree to our terms of service and Swap the cables for the two Z motors AT THE CONTROLLER. Yes, I also was the one who added them in the first place. How to make driver of E1 for motor Z2 on RAMPS 1.4? i.e. 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. TMC lib is 0.7.1. Warranty & Support Information. Ok, hopefully this clarifies a bit more from what I have gotten via "translation" and trial and error regarding dual Z motors.
