In addition, your slicer is emitting arc commands, but you do not have arcs enabled in Klipper. I suggest turning it off in the slicer.
Thank you for quick reply,
I changed baudrate to 115200 (at cfg file in [mcu]) and it worked ok for now (just finished 2 prints which i failed lastime)
Should i change USB cable to UART? 250000 will be better than 115200?
