S42B v2 firmware not working #8

Open rocko1337 opened 3 years ago

rocko1337 commented 3 years ago

The firmware of S42B v2 can be found here: BIGTREETECH-Stepper-Motor-Driver/S42B/firmware/

I flashed it using stlink but it is not working (motor is not spinning correctly). I also compiled it from source code, but I have the same problem. The source code is not working properly.

Bigtreetech, can you please upload the working source code? I would like to adjust the code to send the current position (angle) over uart. Thank you.

I am also having this same issue with compiling. The compiled bin (using the code found here: LINK ) is much smaller than the bin that was originally on the S42B v2.

After flashing the firmware the motor is bricked. Luckily I have two motors and I dumped the firmware from the functioning one (STLINK) and transfered it to the bricked motor, after that the bricked motor worked again. I am 100% sure the source code on github is old and was not updated. Please update the code bigtreetech. Thank you.

I got this from messaging "Btt Tony" on their Facebook page: "Hi, the S42B firmware on our official website is currently an old version, there is a problem. I have given feedback to our engineers and are planning an update."

When will the corrected firmware be released? To adapt to the engine with a step of 0.9 degrees, the original working code is required.

Thank you jubjub64 for asking on facebook! Can you please poke Btt Tony again? I really would like to get the working source code.

I just sent him a request for another update on when it will be fixed. Will report back if/when I get an answer.

I heard back from Btt Tony: "Hi, I'm sorry, I asked him again, he said that he is busy developing S42T recently. He will update the firmware as soon as possible."

Thank you!

Thanks! We are waiting for an update.

Would be really nice if Btt Tony could finally upload it :-|

I am having the same problem, did this ever get resolved?
