    Vinyl cutting techniques leaving 'tabs'

    Hi,

    I'm using small Chinese drag knife (tiny blade), to cut vinyl on my machine, which is mostly working great

    My problem is that because of what Tweakie mentions here:

    "The vinyl dragknife issue is because the cutting tip lags behind the centre of rotation"

    I find that the paths I'm cutting don't quite join up, meaning that weeding involves pulling the scrap free of the 'tab' that's left behind.

    I'm using Inkscape to produce my designs, then Estlcam to produce the tool paths.

    Is there solution for this that means I can cut out the scrap cleanly?

    Thanks

    Can you offset the X and Y axis to compensate?

    Thanks, but I don't know how I would approach that. I would think that the blade direction will be different according to the shape and where it starts on each shape there wouldn't be one simple compensation to do.

    Maybe I don't get it.

    Is it not lining up or are the lines not completely touching / closing? If it's the second issue see if your software will let you perform over cuts. We use Signlab Pro & a Summa S2 140T with factory blades so we dont have those issues

    It sounds to me like possibly the blade isn't adjusted properly for the type and thickness of the vinyl or material you're cutting. The software/cutter should compensate correctly when the blade is correctly installed and the cut pressure is correct.
