Re: G. Weike LC1390N Overshoot problem
Does it happen with all cuts or just some? You need to be very specific about your settings and what will cause this to occur before anyone can help you.
If you tape together a few pieces of copier paper so that you can cut a 300 mm square using your laser, what are the exact measurements of the square? Make sure to mark the piece of paper so that you remember X and Y direction! If either axis is not 300 mm, you need to go into the software and input the correction factor. On a ruida card, there is a place to do this under the vendor settings.
