voron2.4_skr2's Introduction

Voron2.4_SKR2

Tentative Configs and changes to add use of SKR2 boards in Voron Documentation.

20JUN: Added Default configuration, Wiring Diagram PDF, images used in Wiring Diagram.

SUMMARY OF CHANGES:

File: SKR2_Config.cfg

Original file was Voron2_SKR_14_Config.cfg

Remapped all pins to new naming convention on SKR2 board.
- Lines: Multiple
Added [output_pin motor_power] and a multi-pin named "output_power"
- Lines: 95-100
[output_pin motor_power] only allows for one pin to be listed, but both boards must have power applied or UART will fail. Multi-pin solves issue without over-complicating the fix.

File: SKR2 (Rev B) Wiring Diagram.pdf

Mimic'd file Voron2_SKR_14_Wiring.pdf

Generated new diagrams using SKR2 board image.
Added Board Revision check and Addendum A with reference images of MOSFETs.

Don't use the REV A boards. The workaround is annoying, and users are better off returning their boards to the vendor.

Added green "Install Jumpers" box around "U disk/RRF Wifi" jumper pad.

Tested with jumpers in both positions, no change in activation or features for Klipper.

Added stepper driver diagrams, with guidance to NOT cut diag pins.

Sensorless homing now requires a jumper on the pins to the side of the diag pin. Jumper not installed, no need to cut pin.

Moved Probe Power pins on Z board from FAN2 from SKR 1.4 to FAN3 on SKR2.

-NOTE: No Activation Pin required in Firmware to power the Probe with this change. Probe will always receive 24v (if board powered by 24V)

TO DO:

Add section noting which settings to use for "make menuconfig" for proper firmware for SKR2

Need to copy data from Kevin's generic SKR2 cfg. As follows:

# This file contains common pin mappings for the BigTreeTech SKR 2.
# To use this config, the firmware should be compiled for the
# STM32F407 with a "32KiB bootloader".
