The existing interface with graphical previews is poor in terms of responsiveness for large files, and there are several GUIs that are better with preview disabled (e.g. gmoccapy qtdragon)

But they are also slow to manipulate the artifact coordinate offset after loading the G-CODE (the coordinates in the preview are updated).

I created a Flex GUI without a gcode preview or the plotter and it loads and runs a 118MB file with no problems.

I created a test file with this bit of python code

#!/usr/bin/env python3

current = 0.00001
increment = 0.00001
end = 60.00001
nc = []
nc.append('G0 X0.0000 Y0.0000\n')
while current < end:
	nc.append(f'X{current:.5f} Y{current:.5f}\n')
	current += increment
nc.append('M2')
with open('large.ngc', 'w') as f:
	f.writelines(nc)

Change end = 60.00001 to end = 100.00001 and it generates a 198MB file that also loads in a second and runs fine. So the key slowdown is trying to load a file that size into a QPlainTextEdit. I assume but have not tested that the plotter will cause it to be very slow to load.

I tested that the Flex GUI is very fast without QPlainTextEdit and plotter.

The problem is in QPlainTextEdit, can it be optimized not to load the full G-CODE file?
