Using PLA as for settings will have to check. I am assuming you want temp and speed?
That is one of my issues as a new guy and not having a manual for this unit, what the heck are they supposed to be? It looks to me like it would be nice to have some kind of temp reading unit.

Thanks for the advice on the nozzle I will get a few otw!

Being everything is used it could have moisture I will bake also.
