Although inserting a jumper over the X-DIAG and Y-DIAG pins enables the hardware side of the sensorless homing. But further configuration will be required within the 3D printer’s firmware.

It should be noted that although I have a hybrid TFT screen, the detection sensor only works in Marlin mode , since it is not yet fully supported in Touch Screen mode. However most Nema 17 stepper motors has two coils that control the direction of movement. Furthermore the A in diagrams normally represents the positive and the B the negative wires. Moreover each coil has its own set of A and B wires and these should be paired as shown in the diagram above. Limit Switches for Endstops Whereas those who wish to utilise the onboard ESP-07S Wi-Fi module, then a serial port needs defining to 3. #define SERIAL_PORT 3 //Wi-Fi But for those not using a Creality setup, writing a guide for the correct stepper motor wiring becomes difficult. Moreover with so many stepper motors on the market and each seemingly with their own colour coding pattern. Because of this the task is near impossible. Furthermore, some filament sensors use an internal pull-up resistor and require the FIL_RUNOUT_PULLUP option to be enabled. #define FIL_RUNOUT_PULLUP

Similar to the SKR E3 DIP, the DCIN or power in connector on the board is the power connection on the left hand side. Importantly the position of the wiring remains the same regardless of wether you power the SKR MINI E3 V2 with either 12v or 24v.

While enabled by default, there aren’t any 3D printer slicers that I am aware of that actively support ARC movements. As a result, disabling the option saves 3226 bytes of memory, best put to other uses. //#define ARC_SUPPORT BUFFERS

But for those using a standard setup without a TFT display or Wi-Fi module. Then the below example is perfect for the E3 RRF from Bigtree-Tech. #define SERIAL_PORT -1 //USB Základní deska byla speciálně vytvořena pro bezproblémový upgrade a velmi jednoduše nahradí originál.

For example, the X-Axis stepper motor cable will plug into the XM connector on the SKR Mini E3 V3 mainboard.
