I am using PetG at 245 degrees printing on Buildtak heated to 100 degrees. I use a raft and print with no problems. Without a raft the first layer will not stick. Am using maker desktop to print with my Flashforge Creator Pro.

It doesnt matter if the surface area of the print is large or small. I am printing first layer at 30mm/s (same as raft printing speed). I have leveled and re-leveled with a piece of paper barely able to slip under printhead with the slightest resistance.

Why will the raft stick but a non raft first layer not? What logic am I missing in my settings?

Thanks in advance.
