    You are happy with a .0015 error? What are you, a woodworker?

    Okay, just pulling your leg. That's pretty good. How is squareness ?

      I have a Creality glass bed with a coating that is similar to PEI. Grips well with a raft or brim, might lift in a corner without. Prints pop right off after they cool. It does have a heated plate but since I have only printed a few items I have not cleaned it yet and so far no problems. I have only trammed it the one time too. I'm trying to see how long I can go without problems. I probably will use IPA too clean the bed. The alcohol not the beer, that would be a waste but the prints would smell interesting. 3D printing Canada had the filament at my door in 22 hours by courier but I'm only 200-ish miles away. Still that is good service.

      I plan to move on to PETG at some point in the future after I get enough experience with PLA. I'm not printing stature and figurines, my focus is on mechanical things. Right now I'm trying to do a PLA pattern to make a casting mould. The pattern will be burned out.


      P.S. the only problem I have had so far is the filament sometimes get hung up and stops extruding, I will print out a better spool stand or dry box that takes the stress off of the filament and cold extruder. Lots off those on Thinaverse.

      The shortest distance between two points is a circle of infinite diameter.

        Not a woodworker, ever!

        For plastic printing that seems a reasonable error. It is a subjective measurement because your not dealing with machined faces so I expect it will vary over printings.

        Squareness? I've always been a bit of a square, your basic nonconformist. Probably should be on somebodies watch list. HE HE HE......💣 Oh you meant the cube, it looked OK. Again its is printed so it will be different according to what shape you are printing.

          IPA is like cleaning with water, DNA home improvement stores carry for shellac brush cleaning. Takes off grease and fingerprints etc.

            Good to know.

            I had a print pop of the bed so I guess I reached the point where it needed cleaning.

              My bed gets wiped down before every print I have a new green Scotch bright pad cut in 1 inch wide pieces I use to wipe off the nozzle at the same time... after its heated up.

                Darn it, I just started a thread when I could have added to this one.
