For the SKR-Mini-E3-V3.0, the run_current for x, y, z stepper motors has been reduced in the printer.cfg, because the standard current seems to make the steppers dangerously hot. You may have to increase the current, or if the motors are still too hot, you may have to decrease it.

💡 Although stepper motors can withstand upwards of 125C, they should at the most get hot to the touch (~55C), not very hot.

Flash Firmware

💡 If you have already flashed klipper onto your motherboard in the past, you can skip this step.

Please note:

The firmware file must be named firmware.bin.
The firmware files are located in misc/skr-mini.
Many users have reported having issues flashing Klipper using the Sovol microSD card.

Select Your Firmware

klipper-USB.bin compiled by BTT.
klipper-v0.11.0-198-g33b18fd6-latest-UNTESTED.bin that I compiled, however, it is untested.

Build Your Own

Find instructions on how to build the firmware yourself here.

1. Prepare the microSD Card for Flashing with These Parameters

Size: 16GB maximum.
File system: FAT32.
Allocation unit size: 4096 bytes.
Must not contain any files except the firmware file.

2. Flashing Procedure

Disconnect any USB cables that might be connected to the motherboard.
Copy firmware.bin to the microSD card.
Make sure the printer is off.
Insert the microSD card into printer.
Turn on the printer and wait a minute (usually takes 10 seconds).
Turn off the printer and remove the microSD.

Download Klipper Configuration

You can choose either of the 2 following methods.

Method 1: Clone the Repository

cd ~/printer_data/config
Empty entire ~/printer_data/config folder.
- In linux, you can delete files via rm fileName and directories via rmdir directoryName.
git clone -b skr-mini-e3-v3 --single-branch https://github.com/bassamanator/Sovol-SV06-firmware.git . ⚠️ Don't miss the period!

Method 2: Download the ZIP

Download the ZIP file containing the Klipper configuration.
See Step 2 in Method 1.
The parent folder in the ZIP is Sovol-SV06-firmware-skr-mini-e3-v3. This is relevant in the next step.
Extract only the contents of the parent folder into ~/printer_data/config.

Initial Steps

Once you've cloned or downloaded the configuration, please follow instructions found in Initial Steps.
