Man, I hope anybody that runs a CNC knows the difference between vector and raster. We've all experienced it when somebody asks to CNC cut a picture of their dog. Seriously all joking aside, the macropump vs VB macropump comment makes me wonder if the "best practices" are really known to all who customize Mach, and all these sleek screens that look like a science fiction movie do nothing except to impress your wife when she visits the shop. The reality of it is that there is ONE critical process, and that is the proper and timely production of pulses from the LPT port, and anything that jeopardizes that process, no matter how small the impact, must be looked at carefully and a determination should be made whether the additional load's benefit outweigh the risk of corrupting the pulse train and hence destroying a part.... hence my question about the text only screens. I know that I don't really dare to switch screens during a run...especially when I use a smooth stepper. If the part is even moderately complex and there's a graphic of the tool path, it will often conk out while redrawing. Never a good thing.
