I smoked one of the stepper drivers trying to tune motor wife startled me and i shorted it out so bought this BIQU KFB3.0 3D Control Board +LCD 12864 Module Display Monitor Motherboard + A4988 Stepstick Stepper Motor Driver Module thought i found right info 3 times but none of them seem to work. I flashed the board with latest marlin tried the different com speeds with three different MB setting. lcd screen lights up but no data. any help would be appreicated either here or by email Not new to 3d world built my own cnc router and foam cutter for building model airplanes and learning Solidworks too.
thanks don
