hello i have a small cnc
i can cut 370mmx550mm
i have tu make a piece that is 560mm i can machien it under 45 degree but is there a way that i can say in mach 3 that the work piece is under 45 degree because now i have to machien over 12 hours to make the piece and 75 %is just in dead air

is there a useful video about it or a good instrucion manual

thank you for helping me

Not certain I am understanding you correctly but…

In the Mach3 MDI screen you could use Local System Rotate set to 45 Degrees or if you want more complex positioning you could use G68… in your Gcode file.
