I have been getting into more complex designs and I have been looking fo software that will tell me how long my g-code will take to run.
Currently I converting my dxf files to g-code using deskam (for some reason deskcnc won't run on my computer). I then run them on my mill with an old pentium 130 computer out in the garage running turbocnc. This is great for the most part but often I have no idea how long my g-code will take to run and it hard to optimize the code without a program that can calculate milling time quickly.
