    I recently started having a problem where the perimeter comes loose of the infill as if there is a gap.

    I never had this problem in the past and the rest of the print looks great.

    I am using Simplify3D usually. Is there any settings I can adjust to help with this or anything to look for?

    Thanks!

    Increase the infill overlap percentage, maybe?

    I thought about that, but thought that only affected the infill and not the perimeter.

    I did adjust this yesterday though, but didn't help.

    This is new filament I'm trying. I really don't see why this would matter, but thought I would mention it.

    Yea, outline overlap would be my suggestion too. If it is new filament maybe run a temperature tower and make sure you have the best temperature selected.

    If you are using S3D you can use Manual Width and Extrusion Multiplier to move the extrusions closer together, if it is only on layer one then under the Layer tab you would use First Layer Width instead.

    It appears to be with all layers. Right now my width is set to automatic and the extrusion multiplier is set to 1.00.

    This settings have always worked great until recently. I am going to try printing the same object with a different filament I have had success with in the past and see if the problem persists.

    I guess I find it odd that the settings have always worked in the past. I just don't know what could be causing it if it is related to the filament.

    I will try adjusting the temperature or running a temperature tower and seeing if that helps clear things up.

    Also, if this helps. I did upgrade my nozzle to a hardened steel one.

    I don't see an outline overlap option. Just infill overlap.

    Because the reality is that every spool can be different. Usually this is not a big deal and the differences between spools is subtle, but it happens.

    Right, everything else prints fine though besides the perimeters. I will test out the things you mentioned though and see if I can't figure out how to correct or avoid this problem.

    Appreciate the help!

    Ah okay, I must of overlooked that option. That may fix my problem!

    EDIT: This is the option I actually changed to 60% which seemed quite high, but still had the separation of the perimeters.

    Check that the filament extrusion width is set in auto and not a silly number. For a 0.4 nozzle that would probably ballpark be 0.44--0.48
    If auto is using a silly number set it to manual and try that.

    It's set at auto and the number it shows is 0.48 currently.

    might want to check and verify that you do in fact have a .4 nozzle and not something crazy like a .3 or .8/.5/.6. If its an E3D nozzle count the dots. How many dots does your nozzle have?

    That would make sense if the size wasn't right. The nozzle does show .4 stamped on the side though. I wonder if it could be mislabeled or something?

    If you upgraded to a hardened steel and its not an E3D (they dont mark them .4) I'd suggest swapping nozzles to a known good one to be sure its not a manufacturing issue. If all this happened after the swap that would lead me to believe thats the culprit. That said- hardened steel nozzles do occassionally require more heat as they arnt as nice with heat as brass are.

    Ah okay, I am using the same temp settings as before.

    I'm not sure the brand as I have had them for awhile, but I do know they are stamped with the number and do not have the dots.

    I will try swapping the nozzle with a known good one and check the results. I wonder if I could measure the opening with one of my .4mm drill bit needles for cleaning the nozzle and see if it looks right.

    you didn't say drill for cleaning right? SCARY! :D unless you have a .4 pin gauge that wont damage the nozzle I dont suggest it, but it is your machine :D I'd do the swap to a known good one to avoid furthering the problem

    Haha, no it's not an actual drill bit...

    I guess I should of specified. It is more or less a .4mm piece of wire I have used to run through the nozzle to clear clogs in the past. Basically how people use guitar strings.

    I do not use this in a drill lol.
