Marlin 2.0.6 build for Ender-3 and BTT mini E-3 v1.2

thingiverse

<b>Updated 2020-10-07</b> Removed older Marlin 2.0.3 firmware and added new build configuration files and binary for Marlin 2.0.6. Attached a zip file with 'Configuration.h' and 'Configuration_adv.h' to review, along with a compiled binary ('firmware.bin') for testing. <b>IMPORTANT:</b> Use the binary at your own risk! It works on my BigTreeTech SKR mini E-3 v1.2 board with genuine BL-Touch. I have swapped out custom modifications that won't apply to a 'vanilla' Ender-3 / Ender-3 Pro. Read through the 'Configuration.h' and 'Configuration_adv.h' files carefully, noting what options are present and what are omitted. If you use this binary directly on your printer and it causes problems, it's your responsibility. To build, place 'Configuration.h' and 'Configuration_adv.h' in the Marlin folder within a download of the Marlin 2.0.6 firmware. Note that this assumes version 2.0.6, so there may be differences that cause issues if you use a different version. This setup is designed for BL-Touch using the Z-Axis end-stop pins (not the pProbe pins). If not used, comment out '#define BLTOUCH' in 'Configuration.h'. The probe offsets have been set to -43 x, -8 y, and -2.5 z (mm) from the nozzle. Check these offsets, particularly your z axis offset, to ensure you don't experience problems like crashing into the print bed. [The STL is a basic part designed for an obscure Airsoft rifle magazine – included to meet this website's requirements.] <i>Deprecated text follows</i> Customised firmware created specifically for Ender 3 (Pro) with BigTreeTech SKR mini E-3 v1.2 board and BL-Touch. This firmware was built from the standard Marlin repository (version 2.0.3, dated 2020-01-31). Replace the 'Marlin' folder in a download of the Marlin 2.0.x firmware with this customised version. Note that I used 2.0.3, so there may be differences that cause problems if you use a different version. This setup is designed for BL-Touch using the Z-Axis end-stop pins (not the pProbe pins). If not used, comment out '#define BLTOUCH' in 'Configuration.h'. The probe offsets have been set to -43 x, -8 y, and -2.5 z (mm) from the nozzle. Check these offsets, particularly your z axis offset, to ensure you don't experience problems like crashing into the print bed! <i>Edit: found that the bed dimensions were accidentally left set to 200 x 200 mm – Doh! Fixed in new archive: "Marlin_2.0.x_custom_20200202.7z".</i> Good luck with your build!
