Similar fix but a bit easier to apply https://youtu.be/6yggQ2xOTqc It gets more likely that not only the OLED gets issues with the bad 3V3 rail design... missing steps likely because...

normally, one would need 1x 4.7uF "global" +4x 100nF per pin of the STM32. The buck requires at least 10uF itself for stable operation. So, I soldered just one more...

I think, you should maybe read a summary on NEMA17 motor wiring and working principle. You have to connect A and A' (coil A) as well as B and B'...

there is no BOM (part list) provided, afaik.

I experience the same issue for my FDM extruder after powerdown and enabling again. It always stripped my filament as it retracted with max speed x100m of filament. ;) Simple...

I flashed today the latest firmware out of this repo to adjust the PID values a bit and now the enabling/disabling of the stepper driver does not result in any...

Took the pinout from here: https://github.com/bigtreetech/BIGTREETECH-S42B-V1.0/blob/master/Item-Pinmap.PDF  Read carefully the pins as there are two rows of pins (OLED and aux. connector) and one column of pin descriptions depicted SWCK,...

depending on the dongle you have, it should show up as a generic USB device "STM32 STlink" or as a "ST-Link Debug" (STLink v3) with an additional COM-port. If you...

@AbeFM I had also many connection problems in the beginning but quickly noticed, that this happens, if the board was powering the motor (driving the PWM stage). Disconnecting the motor...

I do not see any pins on the nanodlp shield below v2.2 to hook it up. So, I would say, it is only working for v2.2 upwards?
