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
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)
