I use this board in standalone on a mendelmax and it is very nice. You turn the knob and the speed increase while printing. It is a big plus. Only thing I havent found is how to retract some filament while the machine is home positioned ? Before to launch a print No more connection with the computer and that is much better. I use it to slice only. With a 24 V bed, it heat very quick (3mn to get 70°), and same for the hotend. Thanks to Reprapdiscount to furnish 24V Thermistance in the kit.
