If I have Cohesion3d what Controller is good

Hi, my problem is my laser controller, you know that piece of hardware that raises and lowers the bed, and strengthens and weakens the laser ect ect. Well the circuit board fried today luckily my cohesiob3d and other circuit boards survived. I am new to the laser world and I’m unsure of what to get now. Do I need the full kit out of a new controller, or is it because I have Cohesion3D do I just need a circuit board and display. I was looking at RUIDA
