I'm sorry if this has been asked a thousand times before, but I can't find it. What is the difference between the TMC2130 V1.0 and the TMC2130 V1.1? Is it just the fact that one of them has a jumper soldered in from factory whereas the other one doesn't? If so then they'd practically be identical, no?by sevs - RAMPS Electronics
I need a dual extruder capable board for my UM2. Mine came without its main board so i don't know how it's originally supposed to look/perform. Is there any pitfalls to avoid? I don't want to buy something that I just can't use. Is this one good? Geeetech should be an ok brand afaik. Also what are the headers in the top right corner? What do I have to search for to try to find blueprints or sby sevs - Controllers
