    I was changing to a different colour filament and brand and I could see it was not the same size as the previous one, I continued to use it hoping it will not cause a feeding problem, I may have to lower the extruder down one or two present if it does.

    When I got the chance, I put my callipers on it to check the thickness, the Dutch REAL brand showed as 1.78 which is well within the spec. but the other English DTQF brand was 1.87, its something I need o watch for the future.

    Anyone else seen this discrepancy before...

    It's fairly common for filament diameter to vary between manufacturers, and even (to a lesser extent) within the same role roll. The general advice is to measure each roll of filament with calipers in several different places and take an average. The result should be entered into your slicing software's filament diameter setting. Most bowden tubes have in internal diameter of 2mm, so 1.87mm should be a problem.

    My 3DQF filament measures about 1.85mm, whereas their spec sheet says it should be 1.75+/-0.06. It doesn't matter to me as long as the diameter remains fairly constant throughout the roll, which I think it does. Otherwise you might get regions of over/under extrusion within a print.

    This 3DQF stuff is just small enough to fit through the printer without causing any trouble, because its right at the upper limits of size, my current project (Pot plant holder for the misses) has been running for ten hours and showing no trouble at all.

    Did you see the 3DQF filament now comes on rolls with a bigger centre hole, about Feckin time too...?:eek:

    If I could get a good plant I’d have one leaf a day on a sandwich...:hu
    I was always told to eat my greens because they were good for me... :clap
    I always knew that filament could vary in diameter, but I didn’t reckon on been able to see the difference without measuring it first... :oops:
