Cutter starts off well but midway begins cutting drag lines between letters

[Viral0 0]

I have a USCutter MH1351 and am using Signblazer Elements. Machine worked fine for a few weeks but now the blade seems to cut the vinyl when moving from one letter to another, and it's the same issue with images.

 

The first part of the text or image will cut just fine, but midway, about 10 letters in (no matter what the size of the image) the cutter doesn't seem to be lifting quick enough so it leaves a cut from one letter to another or through the image.

 

I have tried a new blade, adjusted the blade, speed to the lowest setting, pressure, Baud Rate, paper guide tension, even tried using different software (WinPCSign) and still get the same issue no matter what I adjust.

 

Any ideas what the problem could be?

ground the stand to the cutter before you fry the z axis chip

my cutter worked well for about 2 weeks then it started to do what you had said. what i did to stop that from happening was i grounded my machine to the stand and then i went one more step and grounded both the cutter and stand to the ground in the outlet on the wall. since then i has not messed up. i been doing alot of big cuts with no more problems.

the cutter itself should already be grounded thru the 3 prong plug the breakdown is the stand it insulated from the cutter if now bonded with a wire

Thanks, this has solved the issue. I spent the entire day adjusting bits when I should have come here in the first place. There are still very faint drag marks even though the blade only protrudes enough to cut through the vinyl and not the backing when I take it out and test it across the vinyl.

 

Could the z axis chip be faulty now? I thought it may be worth replacing anyway as USCutter sells the chip for $5 but as we're based in the UK the shipping cost brings the total up to $100.

true but i figure that a extra ground would not hurt to have. so far its working great.

Viral, just get the number off the chip and find one locally,rather than spend 100 on it

My SC cutter is doing the same thing as the top discussion.  It seems to be dragging on in turns...I installed a new blade but it is not helping.  Please help!  Lots of jobs to do!
