PWM at 187.5kHz might explain, why the OLED communication gets confused. The default setting ist 380kHz (+/-tolerances) which is quite close to the first harmonic at 375kHz of the PWM...

Somebody with more embedded coding skills and time than me might be able to track down the reason for this kind of rare SCLK glitches as they are likely throwing...

@kablek for my setups the OLED corruptions are very rare and I did not manage to capture any glitch that actually resulted in a corruption. Even the SCLK glitches are...

Unfortunatelly, I did not save all the raw data streams and only snipped a few shots. Also not sure, if we would have to completely rewrite the SSD1306 communication as...

> Well... In that case it really calls for complete rewrite... I am probably going to modify OLED code to also support HW SPI with asumption people use wires to...

I am not sure, if we should put too much effort in v1 boards before we know what v2 brings. In my experience, old revisions will just vanish form the...

@swanepoeljan I think, I was mistaken on the optical feedback nema17 motors as I mixed this with the original nanostepper price tag (~40€). But this one is optical hybrid for...

Ok, so I would conclude that BTT sees quite market potential in going forward with this product family. Maybe, they invest also in a senior programming team to get something...

Maybe we really first check that the actually implemented F030 with only an M0-core @48MHz is RTOS capable as it is unfortunately not an F130 with an M3 core. :)...

above it is stated that one could achieve superior print results. I understand better reliability but I am totally unaware of any quality improvment open vs closed in 3d printing....
