![]() Make sure to choose the one with the most recent 'Date modified' if in doubt.ġ4. If you have compiled the firmware a number of times, you may be greeted with multiple. ![]() bin file, right-click and check the file properties. VLC media player is installed on the computer being used and is viewing the file as a video file, to make sure it is a. You should find a '.bin' file in this folder. Navigate back to the main 'Marlin-2.0.x' folder. The final step is to take your newly compiled firmware and upload it to your printers mainboard.ġ2. Return to step 17 and double-check the environment is correct. If it fails, it is most likely to be caused by a mismatch between your board and your default environment. You should be greeted with a 'SUCCESS' message similar to this. The process shouldn't take more than a couple of minutes. Click on the tick and the compiling process should begin. If you can't, you can bring it up by right-clicking on the blue ribbon and selecting 'PlatformIO IDE (Extension)'ġ1. You should be able to see a small tick on the left of the blue ribbon at the bottom of your screen. You do this by removing the two forward slashes ( // ) that come before #define.īefore the firmware can be uploaded, it must be successfully compiled.ġ0. In order for changes to the home position values to take effect, you must uncomment them. ![]() That way you will be able to measure the distance yourself and make adjustments accordingly. Unless you know what the exact offset between your old and new nozzle will be, it is a good idea to skip this step and come back to it once you've completed the upgrade and have homed the machine. The discrepancy in your home position before and after the upgrade will vary from user to user as a result of your machine and your choice of mount. By adjusting the manual home positions to -12 in X and -16 in Y, you can accommodate for the discrepancy and the nozzle will end up in the same position as it was prior to your Hemera upgrade. If this isn't accommodated for in the firmware, you will lose 12mm of Build Area in X and 16mm in Y. You find that the Nozzle is no longer in the same position as it was before. Let's say that you've finished installing your Hemera and go to 'home' the printer. To maximise your build area and ensure no space is lost, you may need to adjust your manual home position settings. 1000 is a good balance to start with and can be adjusted further if you wish.ĩ. On the other hand though, the higher the current, the hotter the motor will be to the touch. The lower the current, the more likely the extruder is to begin skipping steps. This saves you having to recompile firmware if you need to adjust them.ġ000 mA should be sufficient. On many printers, the motor currents can now be changed from the LCD screen. Search for 'AXIS_IS_TMC(E0)' in Configuration.h and change: #define E0_CURRENT 650 You will find it alongside 'Configuration.h' in the tree on the left side. To change motor current, you need to navigate to 'Configuration_adv.h'. Hemera is rated to 1.33A (1330mA) of current. If the gcode instructs Hemera to extrude 100mm, it will extrude 100mm, not more or less! This changes the Steps per mm value from 92 to 397, allowing for accurate extrusion. If you are printing in a particularly cold environment where the temperature might drop below this value, then you may want to decrease this value or heat the environment you will be printing in prior to printing. To ensure the safety triggers work, double-check that Heater 0 MinTemp is set to 5. Refer to this guide for information on max temperatures.Ħ. If you are using a higher temperature version of Hemera, you may be able to increase this. Next we must locate the MAXTEMP values, you can set this value to 300. If the Temperature Sensor type is not changed, this may result in incorrect temperature readings.ĥ. It's worth knowing that your line numbers won't always match up with the ones in the guide so it is better to look for keywords rather than line numbers.Ĭhanging the definition here changes the type of thermistor that the board is expecting input from. 'Thermal Settings') can help to speed up navigation. Using CTRL+F on your keyboard and then typing in a keyword (Eg. Scroll through 'configuration.h' until you find the 'Thermal Settings' section or use Ctrl+F. ![]() Locate 'configuration.h' in the explorer tab and open it: Marlin -> configuration.hģ. If you do not have Visual Studio code or a Marlin source firmware to work from, you should work through this guide first.Ģ. You can load higher resolution versions of images by clicking on themġ. This guide will take you through the process of installing these as well as setting up your Firmware specifically for Hemera. Visual Studio Code is used to compile Marlin 2.0 Firmware with the help of the PlatformIO extension. This is a generic guide for getting started with Hemera on Marlin 2.0 Firmware.
