Within Marlin firmware, there are virtual software-based endstops. These are not a replacement for physical endstops. Especially as a homing sequence first needs completing beforehand to know where the minimum position would be. Instead, they act to prevent each axis from travelling further than it should.

Unquestionably the stepper drivers defined within the Marlin firmware need to match those used on the 3d printer’s mainboard. To use the USART connection we have to connect the UART-TX pin of our Raspberry with the USART-RX2 pin of our board, the UART-RX pin of our Raspberry with the USART-TX2 pin of our board.

Without a doubt being able to change settings and displayed colours of the NeoPixel LEDs make perfect sense. So let’s enable the LED_CONTROL_MENU option. #define LED_CONTROL_MENU Support for expansion: Touch screen, filament runout detection, BLTouch + dual Z-axis (running of a single driver) You want to make sure you uncomment this line. The default value may be different between versions. Although, the alternative method requires some firmware changes. However, it does t Next step on the setup guide to installing the SKR MINI E3 V2, is connecting the LCD screen. Furthermore for many this is likely to be the Creality Ender display, known as the CR10 display.

There are also cut sensors that various manufacturers sell encapsulated and ready to plug. It is certainly the most comfortable, but sometimes the prices are excessively high. At this point, everything should be in place and connected, so the next step will be to test everything. When you power on the printer, you will see the lights rotate through the colors (assuming you enabled the startup test). If everything looks right, your all set. The motherboard was specially created for a trouble-free upgrade and can be used very easily instead of the original.

Note about new version updating strategy

However, for reference, the pin configuration is in your electronics file, in the \Marlin\src\pins folder. Then, you must go to the folder that corresponds to the microprocessor of your board and select the file.
