Run the ground wire from a screw on the bottom of your cutter to the center screw holding on the wall plate of your electric plug outlet.

How do you ground your cutter without the stand?

your plotter is already grounded thru the third (round) part of the plug - the issue of grounding and the stand comes from the vinyl being isolated from that ground  because the stand or whatever you have holding the vinyl roll is not grounded.   what do you sit your roll of vinyl on when feeding the cutter?   keep in mind to prefeed and don't allow the plotter to pull the vinyl off the roll

is there a particular way to ground the cutter to the stand, I think I fried another Zchip. I have the cutter grounded to the stand, it was cutting just fine since the repair, and in the middle of a cut, it acted like it jammed up and the blade stopped its vertical movement and messed up the rest of the cut. I tried the battery test from last time and it works fine, leading me to believe the motherboard is damaged again. I'm at a loss, not sure what I can do anymore.  Aside from upgrading the cutter ( which I plan to do eventually ) what options do I have to make sure this doesn't happen again.

Always use dryer sheets inserted into the ends of the cardboard tubes (vinyl rolls).

Spray anti-static.

Avoid placing the equipment onto carpeting. Dry air conditions are not good (a room with an a/c operating, for example), use a humidifier.

Make sure the ground wire is touching bare metal on the stand, not just the powder-coated surface.

There is also an anti-static kit sold by USCUTTER ---  https://uscutter.com/Anit-Static-Kit-for-Vinyl-Cutters

Thanks for the reply, should I do 1 dryer sheet on each end? where can I get anti-static spray? the cutter is on tile floor, however, the A/C could be causing an issue.

I was thinking of drilling a separate hole with a sheet metal screw to the stand, would this be a good idea? 

How well does the Anti Static kits work, they are only $15, so a small price to pay if they work well.

Elimination of static charge is a step in the right direction. I just stuff the dryer sheets(s) into one end, and anti-static spray is available at walMart or Target, or Grainger or Amazon or ULine.

Drilling a new hole is a good idea, yes.

Not sure about the effectiveness of the metallic string in that kit, but it can't hurt anything! If you do decide to order it, bundle other items like squeegees, app tape, vinyl, weed tool, knife, blank banners, whatever --   to offset the cost of the USCUTTER flat rate shipping.

Best of luck, and doing an upgrade in cutters to a servo unit usually is a worthwhile investment anyway.

Just to clarify, the static you are trying to eliminate is building up on the vinyl itself. The idea behind grounding the stand is the vinyl rest on the stand so the static will transfer from vinyl, to the stand, and then to ground through the grounding wire. The idea behind the grounding kit is you have a piece of metal making contact with the vinyl at all times. You do the same thing with a small, non painted chain, it just needs a ground connection.
