Change starting point

[pilotak]

Is there a way to set starting point to top left corner instead of bottom left? the thing is that the path is showed corretcly in program but on plotter it's mirrored

when i select the option to "Mirror Y" it's displayed wrong but comes as it should

Just select origin, then apply offset:

You need to change your Y-axis direction via $3 https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration#3--direction-port-invert-mask
