Hi

I’ve bought myself a used Biqu B1 with a BLTouch for a fair price. The seller said that he never got the BLTouch working. Now I`m trying to get the auto leveling to work, but every tutorial and video shows the ABL option in the menu, but i do not have that option. The BLTouch is connected as every video and instruction manual shows, the sensor has flipped down a couple of times so that too is working, and the red led-light i always on. Other menu-guides shown in different internet tutorials also shows minor menu variations from my printer.

Some useful info: System: Marlin 2.1.1 Board: Bigtreetech_TFT35_B1_V3.0 Firmware: TFT35_B1_V3.0.26.x Me: Complete noob with no knowledge of 3D printing lingo

What should be done to get the ABL option in my menu?

    You’re probably on the wrong firmware version for ABL. Check the biqu website to see if there’s a version of the firmware specific for use with an ABL sensor. Bigtreetech also has a GitHub with a lot of stuff you can look for it there.

      Thanks for answering. I’ve been looking at Bigtreetech’s GitHub and under Firmware the readme.md states that the newest firmware is “Marlin 2.0.6 (Jan 25 2021 13:43:58)”, this is older than my 2.1.1. The folder structure under are made with dates as folder names. There is a folder newer than the newest firmware stated in the readme.md. But there is no version number, just firmware.bin in folders named SKR 2-F407, SKR 2-F429 and SKR V1.4. I don’t even know what motherboard i have… On https://marlinfw.org/ they say that the current release is 2.1.2.4. Pretty close to mine, but I’m missing the last digit. So I assume the firmware on my printer is self compiled. I’ve watched some videos on how to compile my self, but I’m afraid that with my noob-knowledge i could brick the printer.
