Hello all. Thank you for everything, it everything running. Now I wish to turn off hotend fan below 60C and install a second MCU (a Makerbase robin e3d 2209 drivers) for the mecanical parts (X, Y, Z, extruder) so I can get all the advantages of modern drivers without leaving the PT100 sensors uncovered.
I can't find a cfg that correctly works to turn off the hotend fan and can't find a way of powering the second board using de ultiboard. Any suggestion?
