For PLA you would typically use temperatures in the range of 190-210 Celsius. Printing speeds of 40 mm/s to start with is a good guess. Depending on results you can tweak either temperature or speed.

For ABS you need temperatures around 230-240 C. If you use ABS and then switch back to PLA, make sure you flush the nozzle thoroughly with PLA at 230 C (or your ABS printing temp) to get rid of all the ABS in the nozzle (use the load filament option and let it run a while at the higher temp). Otherwise the ABS may stick there and when printing at the lower PLA temperatures come loose once in a while and blob/block.
