If it has the power to be useful, then it is just a case of configuring a stepgen in hal in velocity mode. The sensible way to do it is probably to keep two completely seperate machine configs. That is what I do with my lathe/mill combo. It makes it easy for the axes to swap their names. (ie in the mill config Axis 0 is Stepper driver 1, but in the lathe config that stepper driver is wired to axis2. You could configure both a position and a velocity stepgen in the same file and switch between them with a set of mux functions and a Pyvcp button, but I think that the two seperate configs is the way to go. http://linuxcnc.org/docs/2.4/html/man/man9/stepgen.9.html explains how to create a velocity-mode stepgen, but it basically comes down to loadrt stepgen step_type=0 ctrl_type=v If you have two of them, one of each type it would be loadrt stepgen step_type=0,0 ctrl_type=v,p You might need to put the config string in quotes, "step_type=0 ctrl_type=v" -- atp ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
