The crossover counters any offset push at one end of the gantry with an equal pull in the same direction at the opposite end. The theory page shows how it works. Having a very light gantry bar on a tight cable or belt would allow it to be lifted enough to be picked up off the top of the torch arm so the torch could be used for both CNC and pattern following without any changes of hardware or anything else to switch. Pick it up, move the arm out a little, let go and jog the gantry out of the way. Then a pattern can be mounted to run around. Does LinuxCNC have H-bot support? CoreXY should drive identically. ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
