Operating System (OS)

Linux

OS Version

PikaOS - 6.17.1

Additional system information

CPU: AMD Ryzen 7 7800X3D
RAM: 48GB DDR5
GPU: Nvidia 4070 Super

Printer

Anycubic Kobra S1

How to reproduce

Import a model and slice it.
Export the gcode and download that on the printer

Actual results

The printer start printing but after the first two layer stop printing and it doesn't respond anymore.
I need to switch the power off to cancel the printing.
If I compare the gcode exported using Orca with the one exported using Anycubic Slicer Next, the code inside is different.

Expected results

Since Anycubic Slicer Next is fork from Orca and the Anycubic Kobra S1 is in the list of the supported printers, it should export the same gcode accepted by the printer.
