MH721 and SIGNBLAZER I have had enough

[Turk 0]

signqueen i am having the same problem with my 721 and it is only a few weeks old.  VERY FRUSTRATED. Was cutting graphics for a race car when it quit half way thru the process.  That is one customer that will never be back.

This is a common problem. I think it is caused by the com port speed of computers being too quick for the low quality electronics used in most chinese cutters. You need to slow the port down in device manager to fix this. I recently fixed a CE1000 graphtec that was cutting garbage on a Vista laptop, to cutiing reliably. Most of the Cinese USB cutters dont have proper USB ports, just an on board USB - serial chip.

Try it, it might fix the problem.
