We now have a Cincinatti Mill running Mach3 in true closed loop on a Galil servo system. This monster is huge, there is a video to be posted yet showing Brian standing on it as it moves about in Gcode. Needless to say to get something weighing in at as many tons as this thing is takes smooth movement, and we seem to have it running pretty well. Still lots to be done, but its gratifying to see it move properly. Probably the largest Mach3 mill running anywhere. So the Galil does seem to work, but before you start snapping up a Galil card, first, they are quite expensive, so definitley not just a general replacement for a printer port. Second, we arent using it in a typical fashion, with all the Galils complex formulas , commands and capabilities, we use about 5 commands or so. We had to use it much as Mach3 uses a printer driver, in a contour mode. We found the Galil very limited in its actual modes, when it comes to
CNC work. For example, Galils dont like to do circles in any more than 2 axis, trying to get 6 axis moves in a galil is a royal pain. Moving to a 4ms trajectory planning interplation seemed the only way to do it, though 2ms is also available to us. We still dont know how well it will all work out, but Brian is pretty happy and psyched with it as it stands. The upside is it allows movement in alll axis at once, and in very complex ways that a standard Galil installation could not do. In fact, the Cincinatti could not be driven by the normal CamSoft software, it just wasnt possible. Mach3 is driving it better than it has ever moved
