If you have done your homework and read our previous article on how Configure Marlin 2.x from scratch, you will know that this file stores more advanced configurations on Marlin, as well as more experimental or in development ones. For this purpose, the ideal – and recommended by me – is that you install Visual Studio Code. I am also copying my final values to the Configuration_adv.h section into the stepper driver X_STALL_SENSITIVITY and Y_STALL_SENSITIVITY settings. StallGuard™ is a Trinamic patented technology that allows load measurements to be made on our stepper motors. Marlin can be found here. Marlin can use this to automatically reduce the driver current if your steppers overheat for some reason. So officially we can affirm that this is the driver that offers the easiest to mount on our SKR v1.4 electronics. Every stepper driver also has it's own microsteps setting. Bug Description The nature of corexy setup is dual stepper movement on a single axis. Importantly to enable sensorless homing on the board is simple. I only have X, Y, Z and E0, so I will modify the values ​​in the corresponding section. with a single search and very easily. With this simple modification should be enough to have a smart UART and StallGuard™ mode, and we will be able to use X and Y motors without limit switches. and then I push my carriages to some distance from the endstops. So let's reset the printer and try some new values for the sensorless homing. And well, so far everything is ready in the Marlin side. Around line 130 there is the #define MOTHERBOARD statement. So it is possible that when you read this article there is a higher version and its name is different. Before connecting your electronics you must select the power that you are going to supply to your board correctly (5V USB or 12 / 24V VDD). In ANY case – they worked once I did this. Hello, my name is Daniel, welcome to the CrossLink channel. There is a very simple way to determine if we already have UART smart communication. Ok, let's now open up Configuration_adv.h to make some more changes. As I've told you in the hardware installation video last time, I am currently using the Anet full graphics display, so I will make sure, I have enabled #define SPEAKER at around line 1772 so it gives me feedback for example when I save my settings. I can’t get it to recognize the printer in touch mode. The second parameter will allow us to support eeprom storage on our printer, it is also essential to activate it. Then as usual, you must connect the DIAG pin of the driver to DIAG1 of your SKR electronic board. Should I set the micro stepping value or leave it automatic? The common setup TMC2130 setup for marlin assumes that the both Aux 2 and Aux 3 on the RAMPS board are available (like the first image of this step). So let's start to modify Configuration.h for the SKR 1.3, So in the author string, I'm gonna put "Daniel's AM8 SKR 1.3 config" just for my reference. The commands are M502, M500 and M501 in this same order. This is something that usually happens on TouchScreen displays. * Higher values make the system LESS sensitive. Well clarified this point … Let’s start! In the v1.4 model we can find a 100 Mhz ARM Cortex-M3 micro, while in v1.4 Turbo the micro it presents can reach frequencies of up to 120 Mhz. And here you can see that for axis, the default value of 8 has been set and we could now try to do an auto home and try if these default values are anywhere reasonable. …again: f****ing awesome guide. Because we are going to use both modes, we will need to make 3 connections on our display board, which are the ones you can see in the image above (click to enlarge). Thanks a lot for share your thoughts with us, and nice to hear that you finally solved it. Also think that you have to do it in at least 3 or 4 motors, the odds as you can imagine of having made a mistake soar. Today, I'm going through all the Marlin 2.0 configuration steps before we can compile the firmware for the SKR 1.3 and then we'll have to do some fine tuning of the stepper motor settings to get sensorless homing to work on this printer as well. Naturally you'll need to have your min endstops wired up or you'll have a machine crash when it tries looking for said min endstop. Now, the easiest way to flash the firmware to the SKR 1.3 is to plug in the USB cable to the PC and hit the upload button in Auto Build Marlin. While this will require a firmware change, we will be covering that in the Configuration.h Marlin setup of the SKR MINI E3 V2. It also enables monitoring of the drivers for overtemperature. The movement is done at a reduced motor current to prevent breaking parts and promote skipped steps. Using the very latest Marlin 2.0 bugfix, they work as expected on my end. As usual, in our SKR electronics we will only have to jumper the MS3 line with a jumper in each of the motors that we want to activate UART and Sensorless. On the other hand, if my printer would start skipping layers, I would know that this value is too low or that my carriage system has such a high resistance that I would need to fix that physically. M915: TMC_Z_CALIBRATION (Deprecated in Marlin 2.0.) Please note, however, that new updates and revisions are released regularly. In fact, in our Telegram channel of 3DWork often enough people with this type of electronics enter to ask questions. After put the drivers in our electronics, and verifying that it connects the DIAG lines of driver and board completely well, we will have UART + Sensorless available. If the homing speed is too low for StallGuard to work reliably, you might have to increase the homing speed - at least TCOOLTHRS cannot help with that, IMHO. I will expose here the different configurations for each manufacturer of TMC2209 drivers and in case I am missing any, do not hesitate to write me a comment at the end of the article and I will try to add it if I have access to the information. You could also just copy the firmware.bin file to the sd card and then insert it back into the printer. I leave you image below so you can see how it was in a user who made this modification. This is certainly a remarkable 20% increase in process speed, which is no small feat. So let’s get to it without further delay. Whatsapp: 608 361 608, © 2019–2020 3DWork - Todos los derechos reservados, Nuestro sitio web utiliza cookies para mejorar su experiencia. Something vital to calibrate the prints on the first layer correctly. Not that it is better or worse than Pronterface (another alternative), but I used it for many years as a Slicer and I use it when I need to send some g-code command. Brilliant guide. Now, a bit below that, around line 2324, I'm enabling SENSORLESS_HOMING. As in my case it is 24V, I indicate it to Marlin in the following way: We activate various temperature protections for our TMC2209 drivers that Trinamic offers us, among other things: We proceed to activate the StallGuard ™ option in our Marlin firmware. First, I'm trying to move the X-Axis to the right from the printer's Motion - Move Axis - Move X menu. Although, in the previous section we recommend you download Marlin directly from the official page, you can also use our Marlin Builder that we prepared some time ago in 3DWork. Of course, try to do it with great care so as not to excessively damage the pins. This will make sure, you are getting the least motor noise possible with these TMC drivers. The wiring image shows how all wires go to the 2 Aux clusters. Bye bye. I will also make another video showing how to install and configure the Bigtreetech TFT35 Touchscreen Color display with the SKR mainboards, so make sure you're subscribed to the channel and have the bell notifications enabled so you don't miss it. However, in the driver it is in the second position, so when you click it it will not be in the correct position. There might also be an EEPROM related error on your display, that's also an indication to reset the EEPROM. You will also need a copy of the Marlin 2.0 sourcecodes on your computer, pre-configured for your printer model. Hi all, after getting a couple of issues resolved on the Marlin Github, there is now a Marlin build that supports an SKR 1.3 with dual y and z endstops in TMC2209 uart mode with sensorless homing. In an ideal world, when we already click the driver on the board it should match, but in our electronics the DIAG pin does not match in the position that you soldered the pin on the driver. And now. I have only removed the driver on the X motor so that it is exposed and you see exactly which pins are the ones that must be jumpered diagonally. It seems you have the most complete tutorial so far on the SKR 1.4 + TMC2209s. I’m using the Marlin firmware, and it’s a few extra steps to translate the gcode for it, but it’s working well. If you have one of these drivers and manage to locate DIAG and activate UART + Sensorless, do not hesitate to let me know, since I have no confirmation that it will be operational. We will start with the parameters to configure the communication ports (main and secondary) and the communication speed. The second serial port is set to 0 and we need to uncomment that line so it actually gets activated. ─║║║║║╬╚╣║║║═╣ It has an easy explanation, the company Trinamic sells the microcontrollers (chips) to the manufacturers directly and they develop their own boards with the reference they have acquired. Recently a colleague sent me a BLTouch / 3DTouch sensor from the Geeetech brand. Currently that's set to 16 and you can increase it to a maximum of 256 on the TMC drivers. Liked it? That's really nice. After having finished both modifications on the SKR v1.4 / v1.4 Turbo board, we will proceed to make the appropriate modifications to our drivers. So yes they can do stallguard if you connect that pin to the right place. Then, scrolling down a bit, you have to change the Serial port settings. To send the M122 command I usually use Repetier. This requires a specific module for this task, and transmission speeds are certainly quite low. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. The support from the programmers is noteworthy. SKR v1.4 and v1.4 Turbo boards have an exact size of 110 x 85mm (102 x 76mm between holes). Already knowing what values ​​we have to use, we will edit “Platformio.ini” and in the field “env_default” we will put the chord to our electronics. And well, for now this is it, I hope this article has helped you. They are as follows: The command that we are going to use will be the M122, in this way a series of parameters and values ​​established in our drivers will be sent to us on the screen, and thus we will verify that they are communicating via UART with our electronics correctly. To change your endstop, you must change the M574 command in config.g. The upload function of Auto Build Marlin copies the firmware.bin file to the virtual USB drive that you will see once you connect the mainboard to the PC. At around line 1072 you will find the settings for the motor directions. Anet A8 / AM8 SKR 1.3 Upgrade with TMC2209 and sensorless homing - Part 1 - Hardware installation. In the end, it also just lands on the SD Card. You must run these g-code commands one by one (don’t insert them at once) and the problem will be solved. Is it moving the filament out? I recommend removing only the X and Y axis limit switches, leaving a self-leveling sensor in Z. The drivers come with Jumper cables, If you use a cable from the top pin for the Diag and connect it to the Signal pin for the end stop it works. I will give you an example. Good, the new firmware is flashed, it's running and the display is also working. It simply means that the v1.3 versions do not have a specific port to connect them to, but you could plug your WiFi module into the TFT connector and remap it into Marlin (for example). I have currently purchased the board and drivers, but did not purchase the display. Let's upload a new build to the mainboard now, to fix the motor direction changes. So what I'm going to do is reducing the sensorless homing sensitivity to 64, that's again in the middle of 0 and 128. I leave you here an image so that I can get you out of doubt (click to enlarge). Our mission is to help 1 million people getting more successful with 3d printing and if you're here for the first time, subscribe and enable bell notifications so you don't miss anything. And then the TouchScreen connector that SKR will use to communicate with the display, marked as TFT in the image. The second option Marlin Builder offers you to download a series of pre-configured firmwares officially offered by Marlin. After having made every one of the necessary modifications, you must test whether UART is already working correctly. Configuring Marlin is very simple, so there is not much magic to get sensorless homing to work. What do you want all the power and versatility of Marlin? Now you must locate on the display where the communication is configured and indicate this same value. So, in my case, sensorless homing worked fine for X and Y but as I said in the beginning, we wanna have this value as low as possible for both axis so we don't get any false positives during printing. And once you have edited Marlin and the necessary parameters – which you will find a little later – you can compile it and upload your new firmware to the printer. What don’t you want to complicate yourself and you’re only going to print? Those sensitivity values determine the amount of sudden resistance on an axis so the TMC driver will think it's hitting the end-stop. I have to confess that the “hybrid” BIGTHREETECH screens are truly spectacular. Trastornados por la impresión 3D, Arduino y Raspberry Pi. But have your hand on the reset button or the power switch because the motors will most probably just continue to run and not stop. Each stepper driver can be configured to have it's own Current setting. Here you have the values ​​depending on which of the two we are going to install on your printer. This feature is so sensitive that it can actually take the place of traditional endstops. Marlin will then rehome Z axis and restore normal current setting. If we only compare the last two models, the only thing that differentiates the SKR v1.4 electronics from the v1.4 Turbo is that it has a superior microcontroller. To test that, we need to heat up the nozzle first with some filament inserted. As these boards have EXT1 and EXT2 connectors as usual, you can use it for other displays without problem. It is not necessary to get hold of the TFT35 display that appears in the article. I want both serial ports to be available for the future. Marlin hasn’t been great in the past at being right when you combine corner cases like that, but sensorless homing and dual endstops have been out long enough, maybe it will work. I've got the exact same setup, except I don't use the stallguard feature of the 2130's yet. We have to go to Configuration - Advanced Settings - TMC Drivers - Sensorless Homing. I had no issues during this 20 plus hour print of the master spool. And to finish with the edition of the file “Configuration.h” we will edit two other very important parameters that we cannot forget. Furthermore this finishes the second part of the SKR V1.4 Marlin 2 setup guide. ─╚╝╚╩╩══╩╩═╩╩╝ Confirm to init the EEPROM, so everything is reset to the default values. If I would see my motors becoming very hot, I would probably take down these values a bit to see whether that gets rid of the problem. It can absolutely be that you will have to change your motor directions after switching to TMC2209 drivers but this depends on what you were using before, so you can just leave it as it is for now and we're going to test the motor directions later to make any neccessary changes here. It is easy to make a mistake on a pin, especially if you have to do many modifications. Regardless of the power source you use, you should always use components that match it. * Lower value make the system MORE sensitive. Next, I'm enabling MONITOR_DRIVER_STATUS. Obviously you will have to do it in all those that you want to activate UART and StallGuard™ (Sensorless). Looks good, everything is compiling and we have a new firmware file. Marlin Builder offers you two possibilities. Unfortunately in this case the pin does not match either, so you will have to deviate the pin again to fit the one on the board. Sensorless Homing work well for X,Y and Y2, but I can't get it to work on Z. I've tried allmost every settings of sensitivity, current, and speed. In this way, we will allow the TMC2209 driver to do it automatically. Lately the new electronic boards of the company BigTreeTech (SKR V1.4 and SKR 1.4 Turbo) are enjoying quite a notoriety within the world of 3D printing. Ender 3 Upgrades – BLTouch sensor with Marlin 2.0, Anet A8 Plus with Marlin 2.0 - Tom Hofman, Anet A8 (Plus) Marlin 2.0 Installation Upgrade. Moreover you simply need to place a jumper connector on the DIAG pin for the axis that you wish to use. To do this, there is a configuration section in the printer's menus. It is likely that after compiling the Marlin firmware and uploading it to your electronics, an Eeprom error may appear on your Touchscreen or the Marlin emulation screen. Regards! Actually, it should not matter in excess of which manufacturer is the driver that you have acquired, since all the functions are integrated in the chip that they assemble. I get a compilation error, which reminds me friendly that I need to change the pin wiring to use the Anet full graphics lcd on the SKR 1.3. All the steps I'm doing are not really specific to this AM8 but can be applied to almost any other printer that you might have. * Too low values can lead to false positives, while too high values will collide the axis without triggering. Modern TMC2209 drivers allow us to perform this function and save us time, money and unnecessary wiring. Ok, We can now take care of tuning in sensorless homing. A bit below those settings, I'm also enabling TMC_DEBUG, just in case I would like to see some debug output of the drivers if I run into issues later. The XYZ parameters to the M574 command are 0 if there is no homing switch for the axis, 1 if there is a low-end homing switch, and 2 if there is a high-end homing switch. I have the SKR 1.3 and the Eryone steppers and through trial and error figured out what you listed here (would have been nice if I found this first). The value 0 means that it will not stop and the value 255 indicates that the slightest obstacle disables motor movement. Before starting with the Marlin configuration, if you are starting from scratch to prepare your new firmware, I recommend that you read this other article before: Complete guide: Set up Marlin 2.0.x from scratch and not die trying. With the Eryone 2209 you can have sensorless homing without the need to bend or modify the pins. In this way, you will save a lot of work in this regard and then you will only have to finish configuring your SKR electronics with TMC drivers with the information in this article.
