Bltouch?

Is there a way to get bltouch to work?

@IoakeimSogiakas short answer? Nearly impossible.

Anycubic ripped out all the support libraries required by a BLTouch (and other library modules as well) to keep the memory requirement down so the compiled code would actually fit on their severely RAM limited 32 bit controller board.

When you try to add in the libraries required for the BLTouch you end up re-writing a LOT of their other libraries because of the dependancy of the BLTouch module.

The best way to get a BLTouch to work? Replace the motherboard, figure out all the wiring for the hot end/end stops/etc, start from scratch with a stock Marlin setup that has all the modules and will compile and fit on the new motherboard.

And sadly at the end of the day, the BLTouch that's usually wanted because of the horrid bed warpage isn't going to fix anything other than confirm the bed is so badly warped the firmware can't compensate for it.

My 2-cents - In my personal experience I noticed that the bed itself is not warped, it's the supports underneath. I bought a manual leveling kit including knobs and springs (or silicone spacers) and was able to finally get the bed level manually ( including two center bolts - 8 adjusters in total)! I'm not sure if the auto bed leveling (LeviQ) contributes anything...

@fubar-life123 In testing we found the same on one of the Kobra's and used a dial micrometer to get it as close as we could and it resumed service.

On another two we ended up replacing the whole bed itself since it was too badly warped. They are working again.

Yet another Kobra refused everything we tried and the end user got fed up with it and parted it out. He later told us the open beam extrusions were warped and that's why we never found the problem.

Pretty much a complete lack of quality control though. Sad to say.
