Anyone doing vinyl cutting? Not Cricut stuff, like big big vinyl

I bought a nice vinyl cutter here about 4-5years ago (USCutter MH 14" machine) & have been really enjoying it.  I stopped spending $ on decals from eBay and Etsy, and had the ability to make custom stuff for my car and Star Wars friends.

But I've discovered it doesn't work very well for long cuts, like 3-4' stripes.  The tracking always moves off when it's rolling back and forth that long.  But it works well for 90% of what I want, up to 10" wide and about the same length, usually more like 4-5" designs.

I'm tempted to spend some $$ on a bigger/better model, something that would do long stripes and bigger things like side artwork on cars (think Subaru STi rally stripes & the like).  I'm wondering if anyone here has experience with them?

I'm familiar with the current MH unit and VinylMaster software (I had plenty of time during early 2020 to practice).  Although I probably still don't know all the options, I've at least gotten to where I'm comfy getting what I need.

28" with stand for about $350 seems reasonable.  MH series. https://uscutter.com/USCutter-MH-Series-Vinyl-Cutter-w-VinylMaster-Cut-Design-Cut-Software/

28" with stand for about $500.  SC2 series but not sure how much this adds moving up from MH.  https://uscutter.com/USCutter-SC2-Series-Vinyl-Cutter/

I never had luck with those, my Roland did do 20 20'x 1.5" square rectangles for a semi trailer job with zero issue. The number of rollers seems to be the key.

In reply to chandler :

# of rollers?  Good to know.  A friend over in IN that did the big door-sized Snoopy for me years ago said using vinyl with sprocket holes was the key.

I've never had a sprocket feed machine, mine have all been grip type and I e cut lots of vinyl that had no edge at all

If you want a boss machine get a Roland.

I have owned the SV-12 (Stika) and the OG Roland that came out before the Stika and now have a GX-24 CAMM1.

The little machines do OK, but as you said they do not have enough rigidity or horsepower for long straight lines.

The CAMM1 is a ripper.  Check the specs.  I bought a (very lightly) used demo unit from a local shop for $800 out the door with a stand.  Couldn't really beat that.
