How to change printing parameters for PA6 in 3D Systems SPRO 60 ?

Hello,I am a PhD student working on evaluating the mechanical and geometric quality of parts printed using Selective Laser Sintering,I have already printed specimens using PA12 powder, and now I want to change the material to PA6 and then ABS,To do that I need to change the printing parameters in the machine,I work on a 3D Systems SPRO 60,Would you please help me how to set the parameters for each material in the machine? I will appreciate your help !Thank you in advance
