## Overview

The BIGTREETECH SKR 3 DC Mode CNC Fan Voltage Control Expansion Module is a precision add-on designed for SKR 3 and SKR 3 EZ motherboards. It allows users to select fan voltages of 5V, 12V, or 24V via an external power supply, optimizing heat dissipation and reducing motherboard damage by eliminating the need for external transformers. This module plugs directly into the motherboard’s 2x4 pin header, offering a straightforward installation that enhances printer performance, reliability, and longevity.

## Description

DC MODE FOR SKR 3 CNC FAN

Review: Best upgrade I've done - It took me a long time to fully configure it with Klipper but when I was done, my printer works better than it ever has and it prints faster and quieter then it did with the silent board I replaced.
Review: Upgraded from SLR 1.4T - The SKR3 controller board is quite a bit faster @ 480 MHz "claimed" clock rate than BTT’s previous controller line up. Installation requires a different board enclosure, since the SKR3 EZ hole pattern has changed. I believe the SKR3 non EZ has the same hole patter as before. There are plenty of SKR3 EZ enclosure model on the Internet, essentially ready to print. The controller has some firmware installed, but who knows what it does. So you'll need to compile firmware that matches your printer. * Don't disassemble your existing printer yet, if you have only one, hi, hi. * ********************************************************************************************************************** For those that upgraded from a previous version, using sensor-less homing on Y / X axis, *** be aware if you removed the Diagnostics pin (TMC2209) in one or another way, you'll need to reinstall it again. *** Otherwise your sensor-less homing will not work. It requires the diagnostic pin to be connected to the socket. The small jumper, used on the SKR3 EZ, will direct the signal. This is not required with the EZ TMC2209 driver, aside they don' have these pins. ********************************************************************************************************************* Other than that, it will work just as your previous setup. Perhaps you may have had the hot-end cooler fan connected to the HE1 header. In this case the fan runs on "board voltage supply". If the DC/DC module is installed, one has now the choice to select 5V or 12V fan supply (buck converter) as supposed to the board voltage. The Hot-End fan can also be moved to one of the fan header (requires modification of firmware). There are now 3 controllable fan header that will get their supply voltage from the DC/DC module (if Installed and setup). I guess this option is useful to original Prusa printer having 5V fans. I have another printer that runs the SKR3EZ board with TMC2209EZ driver, for a while. The only thing, I believe, that has not caught up to these boards, is probably the Marlin Firmware. This printer does on occasion some unexpected stuff (deviating from a certain sequence), but I think it is firmware related. Otherwise it prints flawless! I recommend some form of cooling to the driver, perhaps simply a fan blower at the bottom opening of the board enclosure?

## Features

- 【CNC Fan Voltage Control Mode】BIGTREETECH DC mode is an add-on CNC fan voltage control expansion mode installed on SKR 3 /SKR 3 EZ motherboard for better heat dissipation.
- 【Voltage to Choose】It will be easy to choose 24V, 12V or 5V voltage with this DC module through external power supply while using BIGTREETECH SKR 3 or SKR 3 EZ mainboard.
- 【Reduce Mainboard Damage】BIGTREETECH DC mode will keep you away from the trouble of external transformer and thus reduce damage to the SKR 3/SKR 3 EZ motherboard.
- 【How to Use】If you choose DCIN as the power supply of CNC fan, short circuit the two pins of VIN via jumper cap; If you choose 12V or 5V as the power supply, short circuit the two pins of VOT via jumper cap, and insert SKR 3-DC MODE to the 2*4Pin female row of VOT and VIN.
- 【Tip】Please let us know directly through desertcart if you have any problems about our products, BIQU customer service team are always ready to offer help!

## Questions & Answers

**Q: Does this board support a dual extruder / hot-end setup?**
A: Yes it does.

**Q: Will this work on an ender 2 pro?**
A: Yes

**Q: Will this work with the bigtreetech pi tft43 tft lcd display (https://www.amazon.com/dp/b09791zg1b)?**
A: Not directly. The pi tft43 needs to connect to a Raspberry Pi via dsi cable. And the Raspberry Pi needs to connect to the BTT Manta mainboard via usb cable for touch screen functionality and more.

If you want a display to work directly with the BTT Manta mainboard, Look at BIGTREETECH Direct TFT50 V3.0.1 5.0.

**Q: I had an skr3 with the 743 chip, what do I change in the firmware for the 723 chip?**
A: Please go to our Gitup for the firmware update

### ⭐⭐⭐ I WANT to like it
*by C***D on January 5, 2025*

So, it's a neat idea. Compact form factor and all the output and functionality you need with nothing you don't. I got it working, but would I do it again? Well, it's supposed to work with Marlin, but good luck with that. If you have the skill to make it work, why would you. I tried while I was tinkering because I'm well versed Im marlin and wanted to troubleshoot before adding klipper while my CB2 was shipping. So, it must be good once klipper is installed right? Well, not really. it's more compact than a board and a pi, sure. But if you're building it into anything larger than an stock ender that doesn't really matter and even then, you have to print a custom case which by the way, the one big tree tech provides an STL for is terrible. Go on thingiverse and find a better one, which make the electronics enclosure larger, which kills the point of the board. The whole size of a stock board thing is sort of a salesman lie. It bolts up the same, but it is larger and the wiring is TIGHT and you won't have access to some of the ports if you use the provided case. Oh also, it's a lot easier to use auto power off features if you use an external pi because it's much trickier to shut down a compute module, before powering off the computer. It might not be possible at a, I'd have to dig more but if it is possible big tree tech should have that info in the github because it would be very useful, the fact that it's not makes me think they didn't think that through. A normal raspberry pi has it's own power supply so you can power it separately from the printer to use a clean power off cycle. it works, but it's not what they advertise and a version 2 will hopefully fix that, but it will be too late for me. I won't be using this or any manta again for another build without a HUGE overhaul.
