I try to remake my Ender 5 3d printer into a ceramic printer. I added second stepper motor (ender only had 1) but when I connect both stepper motors directly into the board it wasn't enough power for one of the motors. I tried to power this motor from power supply unit but it doesn't work correctly (motor skip stepps). How should I connect everything so that it works? Is it even possible in this configuration? I have arduino but I prefer not to use it if it isn't necessary.

Thank you in advance
