Hi Karen, There is some interest in this kind of functionality within emc. It would be handy for either sinker or wire edm at the least and you apparently have thought of another use.
If one can program in Tk/Tcl then modifying tkemc to provide this kind of movement should not be too difficult. No one has done this to my knowledge. I tried an external approach where I drove emc with emcmot and then attempted to provide input to emcmot by piping input from a small C program to emcmot. The C program watched a couple of pins on the parallel port and responded according to rules in the program. Unfortunately, the parts would work separately but the pipe failed. (Maybe someone knows why and can point me in the right direction). :-) Reverse movements should not be tried with G0 in two or more dimensions as it is rumored that G0 doesn't have to follow a coordinated path to the destination. In addition there are some hooks into emc using Python and Axis but I'm completely at a loss there. BTW-the reversal process also works for G2/G3 by inverting the sense of the curve to go backwards. Hope this helps and maybe someone with better ideas will respond. Dave On Jan 28, 2007, at 12:30 PM, Karen hov. wrote: > Dear Sirs, > > I use TKEMC software & I have a question.
