🚨 One-Stop-Shop Sovol SV06 Klipper Configuration

This branch contains the Klipper configuration and firmware for the Sovol SV06 3D printer with the BTT SKR-Mini-E3-V3.0 motherboard.

For the Sovol SV06 with stock hardware, please refer to the master branch.

For the Sovol SV06 Plus, please refer to the sv06-plus branch.

For all other 3D printers, please switch to the any-printer branch.

I am creating these files for my personal use and cannot be held responsible for what it might do to your printer. Use at your own risk.

🙏🏻🙌🏻 A big thanks to transistor1 for getting this printer.cfg up an running to begin with.

Installation Instructions

Electronic Wiring

Wire cables according to the following diagram:

Download Firmware

💡 The firmware files are located in misc/skr-mini. 💡 Be sure to download the raw files. Find out more about this here.

Download klipper-USB.bin compiled by BTT.

Or you can download klipper-v0.11.0-198-g33b18fd6-latest-UNTESTED.bin that I compiled, however, it is untested.

Alternatively, find instructions on how to build the firmware yourself here

Flash Firmware

⚠️ Make sure the microSD card has been prepared using the instructions found here.

1. Rename whatever firmware file you're using to firmware.bin. ⚠️ If the file is not renamed, the bootloader will not be updated properly.
2. Copy firmware.bin to the root directory of the microSD card.
3. Power off the skr-mini-E3-V3.0.
4. Insert the microSD card.
5. Power on the skr-mini-E3-V3.0.
6. After a few seconds, the skr-mini-E3-V3.0 should be flashed, but wait a full minute just to be sure.
7. You can confirm that the flash was successful, by running ls -l /dev/serial/by-id/ or ls -l /dev/serial/by-path/. If the flash was successful, you'll see something like the following:

Download Klipper Configuration

You can choose either of the 2 following methods.

Method 1: Clone the Repository

1. cd ~/printer_data/config
2. Empty entire ~/printer_data/config folder. Unfortunately, for safety reasons I will not post this command here. However, in linux, you can delete files via rm filename.
3. git clone -b skr-mini-e3-v3 --single-branch https://github.com/bassamanator/Sovol-SV06-firmware.git .

Method 2: Download the ZIP

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

⚠️ Important Note About Stepper Motor Current

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.

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