Why is this happening - only because of diameter size - 1 mm? Or i am doing something wrong? How to avoind this in engraving?
I've used "area" to make pathes.

Re: Rounded corners
Your G-code is correct,
but LinuxCNC rounds the path to increase the processing speed.
You can use the G61 at the beginning of the program file, then LinuxCNC will move exactly along the path.
Or you can use the G64 P0.1 - in this case, rounding is not more than 0.1 mm.
for example:

for example:

G61 (exact path mode)
G01 X0 Y0 f3000
G01 X100
G64 P10 (rounding with a 10 mm tolerance)
G01 Y100
G64 P30 (rounding with a 30 мм tolerance)
G01 X0
G01 X0 Y0

Re: Rounded corners
This problem is not the result of selecting rounding mode (G61 / G64).
Your machine (motors) lost steps.
Possible cause of of missed steps - is too high acceleration.
Perhaps the reason for the lost steps are electrical interference.

Re: Rounded corners
Now is much better, one screw was no tight now it's not perfect but ready for more testing and tunning my cnc -this one was without G61.
Thanks for your help!
