Imagine, I've generated huge program for hundreds of parts in a 6meters long sheet, It starts cutting, and I see that offset is wrong. FreeCAD doesn't have this feature, it is a big misfortune. Oh, forgot to mention - G41 and G42, tool diameter offset. And off course I tried to use FreeCAD here, with partial success. Last machine was easiest for me, there was no cutting control in the code, everything is in predefined recipes, so you need to only give command to move and to lift up, and get down the head, every piercing is done automatically and contour is cut by a recipe. Third uses it's own subprograms with options that manufacturer doesn't want to uncover because "there is a postprocessor for that program of this developer that you can purchase". One machine writes piercing, leadin/leadout and every needed parameter in the end of the file in format that only machine understands (no explanation for these magic numbers), Other needs to set everything, including corner management in subprograms. I am not a plasma or laser or waterjet specialist, but I've had to set postprocessor in Lantek for four different plasma machines in the past. No silver bullet in this area.Ī lot can be done with job templates and setup sheets but there is plenty that still needs to be developed. And add to this how different controllers can be, No, I don't believe it can be done. Man I hardly imagine it would be done without serious material management, torch management, corner management.
