Hello all - long time lurker from Australia here. I purchased a second hand KNK Maxx 24" approx four months ago and have been trying to get a full sheet of saleable vinyl decals ever since ... I have around a 30% success rate.
I have been setting my V at 350 and F at 35, have my vinyl attached to the plastic KNK matt, have changed blades, I've tried going offline mid-cut and adding more Force or dialling the blade down in the holder yet it simply isnt cutting right through my vinyl enough to peel it off easily OR when I do get a good cut, which peels off the backing easily the KNK has done random zig zag cuts going back to the start point and cut extra across my MTC projects. I have been doing quite simple designs (large letters for a dressage arena, large solid silouettes of animals etc) and they are then ruined when they have these extra cuts on them.
I'd really appreciate some words of wisdom from all the KNK guru's here - I've been trawling the forum for months and am pretty sure I've covered all bases.
