@bear_lab Looks promising! Which ones are you currently using?
I always was a fan of the BTT Octopus - but there seem to be good alternatives today
@brokenminded I'm not a fan of BTT, especially the connectors and I struggle to trust their design (too many customers have been used as beta testers in the past). Other "aliexpress vendors" have the same issues to me. So I use a Prusa Einsy and a Duet Mini 5+ (all genuine obviously).
@bear_lab Yeah, I remember version 1.0 of the Octopus - VCC and GND where swapped on the board's labels. You get what you pay for ;-)
@brokenminded Yeah absolutely, always like this with those brands.
This new board has interesting connectors, looks to have carefully designed power supply and is full of options. I would prefer soldered drivers but I can live with this. I think it's also a good base to fork for a more custom design as well.
@bear_lab That is an insane amount of connectors.
@kevin Correct :D
