Einsy Rambo Question
Just a quick question about this Board, perhaps someone can chime in.
The MK3 uses 24 Volts as the PSU, and Prusa stated in the Blog post that
"We had to switch to 24V to get the right amount of juice from the motors and the heatbed"
New 24V PSU for 24V Heatbed and Extruder i can understand, with faster heatup times and all, but how didn't 12V work out as a voltage when Stepper Motors are current driven anyway?
Also Ultimachine's green Einsy Rambo is at version 1.1, with the added changes:
Added 2Mb serial flash
Added voltage translators for serial flash
Added tri-state buffer to block 3.3V MISO on the SD Card from the 5V MISO bus
Added barrel-relief to bottom side of thermal vias for TMC2130, FETs and SMPS
Added 3.3V LDO for serial flash
What's the Board revision for the black Prusa Einsy, does it incorporate those changes and are there other changes on Prusa's Board?
