Vevor KI-870A - Problem w/ Calibration

Recommended Posts

*UPDATE* Sorry, just realized I think I posted this in the wrong forum.... my cutter isn't MH series..

Recently bought a Vevor KI-870A with the intention to mainly cut htv. 

When I try and cut vinyl or plot with pen, the corners don't register properly and I get the issue seen in the image attached.

Would love a solution please! TIA..

I have a KI-720.
Offset setting is wrong.
For cutting vinyl you need another offset setting as for the pen.
At your picture on the right is for offset calibration. To me it seems that A-0 and A-1 are best performed. When performing this calibration process you have the opportunity to enter the values (A-0 in this example). And it should be all good.
Set the offset setting for the purpose that you are going to use the vinylcutter. If you're going to cut vinyl, use vinyl for the calibration process.

The first thing you must make sure of, is to set your blade depth correctly, do not use the thickness of a credit card or post it notes. This is wrong and too much blade exposed out of the blade holder.  Follow these directions.

To start with, you should set your blade depth correctly, by taking the blade holder out of the machine, and firmly cut across a piece of scrap vinyl, you will be cutting. You should only be cutting the vinyl and barely a mark on wax paper backing, Adjust blade to get there, Then put the blade holder back in machine, and use the force of the machine to get there, same results, only cutting the vinyl and barely a mark in wax paper backing. You should barely see and feel the blade out of the blade holder. Regular sign vinyl is only 2-3 mil thick. You only cut with the very tip of the blade. When you think the blade is so far in the blade holder, that you wouldn't think it would cut, it is probably correct.  look at your TEST feature on your vinyl cutter. 

After getting the blade depth correct, start with 0.25 mm offset, adjust at .05 plus or minus til it looks good.      Pen testing is zero offset.
