* Lower value make the system MORE sensitive. The first file that we are going to modify is the “Platformio.ini” to indicate to our compiler what type of microprocessor we have in our electronics. Your email address will not be published. In about line 593, I'm changing X_HOME_BUMP and Y_HOME_BUMP to zero as we are going to configure sensorless homing for this printer and that won't work with home bump anymore. With this parameter we will have a more accurate signal for our drivers. And that also tells Marlin that it's used in UART mode, otherwise it would be standalone. If you are a maniac with cables, you will appreciate being able to remove all that extra wiring from your machine and leave everything cleaner. If your power supply is 24V, the fans you use must be 24V (otherwise you can irreparably damage them). I only have X, Y, Z and E0, so I will modify the values ​​in the corresponding section. If your are using a LCD with SD Card adapter, Aux 3 is not available and wiring for that situation will be discussed in the next Step. Now we are going to tell Marlin exactly what type of electronic board our printer has. This file is located inside the Marlin firmware, exactly in the root directory. Marlin can use this to automatically reduce the driver current if your steppers overheat for some reason. Probably it was not necessary to remember it but it never hurts, since there are several components to consider. It is my duty to inform you that they are affiliate links to different online marketplaces online stores. This feature is so sensitive that it can actually take the place of traditional endstops. 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. 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. The next thing you should do, of course, is download the Marlin sources – or source code – to your computer. The rest of the components of the printer such as the number of extruders, speeds, printer size, temperature parameters and many other things we already explained previously in the article that I indicated a few lines above (Complete guide of Marlin). 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. 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. To do this, there is a configuration section in the printer's menus. Here around line 2236, make sure STEALTHCHOP is enabled for all stepper motors. The middle and right solder connection works on the skr 1.3 but not the 1.4. Regards! Or if you wish, through our social networks. 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. 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. For your hard work Good, the new firmware is flashed, it's running and the display is also working. And with this, we would already have everything configured. And although it is hard to believe, that function exists since version 1.x.x of Marlin!. ─║║║║║╬╚╣║║║═╣ As you can see in the following image (click to enlarge), they changed the position of the DIAG of the vertex of the triangle to another position, which turns out to be the same as that of DIAG1 of our SKRs, a great success for users of these electronics. If I turn the knob to increase the value, it should move to the right. Very good. ╚╗║╠═╦╦╗ ☆° Also, if you feel like it, you can always visit us at our Telegram channel, and if the necessary information is not documented help us complete the article to facilitate the same process for other users. So, it's actually moving in the wrong direction. You must run these g-code commands one by one (don’t insert them at once) and the problem will be solved. and then I push my carriages to some distance from the endstops. And don’t forget to add us to our social networks (Facebook, Twitter, Instagram), this way you will support the 3DWork project. 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. So officially we can affirm that this is the driver that offers the easiest to mount on our SKR v1.4 electronics. 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. Regardless of the power source you use, you should always use components that match it. Also using the push dial works fine to navigate the menu. By the way, perhaps will be better try to use a more specific electronic board, drivers and motors for build one CNC Mill. You will need a computer with Visual Studio Code installed, and the PlatformIO and Auto Build Marlin Extensions for Vistual Studio Code. We explain it in the next section. Quite deep inside. Another important detail is that the SKR electronics support 12V or 24V. Double interface for the Z axis, support for external power modules, support for LED strips, and some other things. Then I leave you some official images of the manufacturer where you can see all the connections and sockets of the electronic v1.4 and v1.4 Turbo. Using the very latest Marlin 2.0 bugfix, they work as expected on my end. StallGuard™ is a Trinamic patented technology that allows load measurements to be made on our stepper motors. I usually use optical infrared sensors for my printers, but I wanted to try the BLTouch sensors since none had fallen yet by my hands. I have changed the baudrates and ports but the message no printer not connected continues. Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. Sending a GCode of some megabytes can get you desperate, so at this point it is more advisable to use a Raspberry Pi with Octoprint for such a task. ╚══╩═╩═╝ ☆° ─╚╝╚╩╩══╩╩═╩╩╝ Each stepper driver can be configured to have it's own Current setting. When I first read that these displays emulated both modes, I was pleasantly impressed, so I decided to purchase one for myself SKR electronics without hesitation. And we're crashing into both axis, so we are way too low with our values. Modern TMC2209 drivers allow us to perform this function and save us time, money and unnecessary wiring. Sensorless homing up and running on the new Skr v1.4 turbo+TMC2209s! It’s Greatly Appreciated. Hi Devin, Regards! If we do not indicate it Visual Studio Code you would have problems compiling our firmware. SKR v1.4 and v1.4 Turbo boards have an exact size of 110 x 85mm (102 x 76mm between holes). It may seem strange, but in this way we will avoid adding unnecessary cables. Thingiverse is a universe of things. Something vital to calibrate the prints on the first layer correctly. Having different sockets for all types of displays, specific BLTouch/3DTouch connectors, ease of use with TMC drivers without external wiring, specific connectors for LED strips, removable protection fuses and a few other things are just some examples of how it has targeted BigTreeTech the market quite successfully. If someone can give you some recommendations about it that have experience with this will be great. i spent days trying to figure out the UART connection issues on my SKR1.4 turbo / watterott TMC2209 combo. To change your endstop, you must change the M574 command in config.g. 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. For sensorless homing, the default sensitivity setting should be ok for most printers, but of course you can play with it if it is too sensitive or not sensitive enough. 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. 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). MENU -> CONFIGURE -> UART SPEED. 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. And this does not mean in any way that the TouchScreen mode is not complete, vice versa. In the image above you can see how I did it. In my printers I leave microstepping as it comes from Marlin, and drivers I use 850, 850, 850 and 600 (X, Y, Z and E0). Should I set the current values or just ensure the Rsense resistor value is correct? That is correct. I am setting up my drivers as UART without sensorless homing. I leave you a list here of the different SKR models and on your right the parameters that you must enter: I have a v1.4 Turbo, so I indicate it to Marlin as follows: Then we will configure the type of driver we have and the motors on which they are mounted. Then you just have to follow the instructions in this article and you can enjoy your new electronics quickly. For this purpose, the ideal – and recommended by me – is that you install Visual Studio Code. I leave you image below so you can see how it was in a user who made this modification. They are very easily distinguished since, as in the previous driver, the name and version are printed on the top of the plate. If you have followed this manual to the letter you will remember that we set the communication to 250,000 baud in Marlin (#define BAUDRATE 250000). Thanks a lot for share your thoughts with us, and nice to hear that you finally solved it. The support from the programmers is noteworthy. Then, you can give your printer a name that is going to be shown on the printer display later, I am using "AM8" for now. After having left Marlin completely configured, we will proceed with the changes at the hardware level of our electronics (SKR board) and TMC drivers. Now, let's scroll down to the tmc_smart section, around line 2024 and below. You can also configure the sensitivity with the X_STALL_SENSITIVITY and Y_STALL_SENSITIVITY parameters. I also wanna make sure that my serial connection speed is set to 250000, so we have a higher speed. 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. With the Eryone 2209 you can have sensorless homing without the need to bend or modify the pins. And at around line 2031, I have enabled ANET_FULL_GRAPHICS_LCD, and at line 1842, I am disabling the original Anet A8 ZONESTAR_LCD. You simply have to select the brand and model from a dropdown and press the download button (see image above). This option offers us the possibility of using a series of very interesting GCodes to monitor the TMC2209 drivers. 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. This is something that usually happens on TouchScreen displays.
