Name abbreviations were required for the Creality boards due to limitations in their toolsets handling of long filenames in Windows. That's why they look different from the SKR entries.
Key to Filename Feature Indicators:
- BIL - Bilinear Bed Leveling
- UBL - Unified Bed Leveling
- DD - Direct Drive (short path from extruder to hotend)
- DZ - Dual Z Steppers; One Z stepper motor cable in Z1 or Z2, the other in E1
- GR - Graphical Display (TFT35)
- SKR14 - BigTreeTech SKR 1.4 Main Board
- SKRMINIE3_20 - BigTreeTech SKR Mini E3 v2.0
- Slnt - Creality Silent Board
- Stck - Creality Stock Board
Pinouts for the connection of the Creality touchscreen to the BTT SKR boards can be found here: https://imgur.com/rGRCmfs. Please note that the Mini E3 pinouts on the TFT socket are the same as the SKR 1.4.
If you're using a Creality board, no wiring modifications are needed.
The screen flash files have been extracted from the original Insanity Automation distribution and are in the file list above as DWIN_SET.7z. You'll need 7-Zip to decompress them. Copy the extracted DWIN_SET directory to a 4k-sector FAT32 formatted micro SD card, insert it into the display's card slot (you'll have to open the PSU case to get to it), and power on the printer. You'll see a lot of text and images flash on the display; it will tell you when it's complete in the upper left corner of the screen. Remove the SD card once it completes.
For the BTT SKR board configuations: These builds assume that you are using the SERVO and PROBE ports for the BLTouch and not the Z endstop port. Also, please make sure that you follow the wires back to the BLTouch itself to verify correct wiring. There's a diagram in the respective board's documentation. IMPORTANT: The pins for the PROBE port are the reverse of what Creality uses. If you simply plug the 2 wire connector into the PROBE port, it will not work. You will neeed to either swap the pins in the plastic shell at the end of the wires, or cut off the plastic tab that aligns the plug in the socket and rotate the plug 180 degrees to insert it "backwards."
Additional documentation can be found at the Marlin Home Page. Please test this firmware and let us know if it misbehaves in any way. Volunteers are standing by!
Marlin 2.0 takes this popular RepRap firmware to the next level by adding support for much faster 32-bit and ARM-based boards while improving support for 8-bit AVR boards. Read about Marlin's decision to use a "Hardware Abstraction Layer" below.
Download earlier versions of Marlin on the Releases page.

Marlin is published under the GPL license because we believe in open development. The GPL comes with both rights and obligations. Whether you use Marlin firmware as the driver for your open or closed-source product, you must keep Marlin open, and you must provide your compatible Marlin source code to end users upon request. The most straightforward way to comply with the Marlin license is to make a fork of Marlin on Github, perform your modifications, and direct users to your modified fork.
While we can't prevent the use of this code in products (3D printers, CNC, etc.) that are closed source or crippled by a patent, we would prefer that you choose another firmware or, better yet, make your own.
