Hello, everyone.
I am new to laser things and I use Lightburn for several months. From version 0.20 I noticed a problem. When I send a bigger file to the laser, a communication problem appears (i use USB) - while the progress bar is active, strange things happen with the task I send - first start good, but then the lines (pases) begin to diverge. Therefore I have to send the work with the Send button and not with a Start (but i love the start button better 
Is the machine weak - when it calculates does not communicate well?
Or something else happens?
Windows 10 64bit, i5 - 3Ghz, 12Gb RAM, Laser machine - MIra 7, Ruida
Thanks in advance and sorry for machine translation
