Hey everyone!
Sorry for late reply, but I am really busy.
Just wanted to let you know what was the problem. It was nothing else, than a wrong configuration. You can setup any plotter cutter in two ways:
1. Install USB drivers than add your plotter as a printer (than you are using spool service).
2. Install USB drivers and add plotter through your COM port.
If you use first option you must bear in mind, that if you are cutting big and/or complicated designs, your are going to overfill printer (your plotter set up as printer) buffer quite fast. Ergo, print spooler will go crazy for sure (if your OS is Windows of course).
If your plotter cutter behaves like crazy, it cuts designs well in the beginning and than it cuts some strange lines, be sure to check, if it's not configured as a printer. If it is, definitely change configuration and set it up ONLY on a COM port.
That was my mistake even, that lot's of manuals show to set up plotter that way. It's a wrong way. I knew that I've made mistake somewhere, but I didn't know where. Than I checked everything AGAIN, step by step, starting from USB drivers installation. That's how I realized, that plotter should be set up on a COM port only (it doesn't matter if it's COM1, 2, 3, 4 or whatever number it is). There is no need to add plotter as a printing device. Next thing you should check (especially if you use SignCut Pro) is the connection speed on your COM port in Device Manager (check the screen - the default speed is 9600kbps which is absolutely enough).

If in your SignCut cutter settings you have option "Use Windows serial setting" checked, but your plotter doesn't want to cooperate, don't throw it away yet, just uncheck this option, set up connection speed manually and everything should be fine now
There, hope it will come in handy to people with the same problem, because I read a lot how to solve it and I haven't found solution anywhere

P.s. Sorry for my grammar, I am literally exhausted and my brain doesn't want to cooperate with me
