Q: DC Buck Converter for uTracerNXT/Filament Recommendation

[Andrei V]

Hi,

What external DC buck converter from Aliexpress would you recommend for external filament supply? My previous experience with several of them was quite problematic - along with power supply they deliver huge amount of HF noise, which made sensitive circuit unusable. No CLC filter was able to reduce it to meaningful level. I've got 30mV of noise from output (with shorted input) instead of 0.3.

Thanks in advance

Andrei
