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?

I bought a bl touch a few years ago. Decent printer. I updated the firmware and added a bl touch. That's when it all went wrong. I now recommend staying away from biqu as their customer service is non-existent. To your problem, as stated by another commenter, get an updated firmware from biqu's site. I compiled my own, which may explain some of my issues. My initial issues came with the probe offset. I dug a deep line in my plate and took several attempts to realize that I need to change my offset only in the machine parameters, not in the abl menu.

Thanks for answering. Found a post on Reddit about getting the BLTouch working on stock firmware, it all went well until the printer stated that "unknown command m851".. I've looked at the firmwares on Bigtreetech's GitHub, but I found it just confusing. The newest I found there is older than mine. After all youtube videos I've watched and all reading i have done, none have mentioned that the offset parameter is just set in machine parameters and not ABL. Thanks for this.

That may have been a quirk due to compiling my own. I believe I did that because I found myself in a similar situation of not seeing a more recent firmware. If you decide to replace this one, I'd recommend an anycubic. Got a Kobra 2 NEO, and it works great straight out of the box. Similar price range, too, $150-$200.

Think I'll try to cook something up, flash it and hope to be able to recover from any failure.. Got the printer a week ago and paid like $80 for it. Looks like the bed isn't 100% flat and sinks a little in the middle so I should be great to have the BLTouch working. Not ready to give up in this one just yet.
