I thought I'd try to get Perl/Tk going on my Win95 machine and run a simple "Hello World" script just to see what was involved. I searched around a bit and found this

Guys, I am all for porting this puppy over to my fav. OS LINUX. However, I am concerned that if people have to purchase new controllers, expensive ones at that, we may slow down the "market"

Thanks Fred and Matt for the fast action on this. I will admit that I know a lot more about Perl than tcl, so Im biased to think I can do a better job with Perl. I Perl for Windows is just as

Ron Ginger expressed some doubts about the suitability of Tcl for an EMC GUI, mainly about its ability to support his foundation data structs: object orientation, modules, and variable namespace. In

Maxnc( pro deluxe), cncpro and DeskNC all use single ports. Pin 2 x step, Pin 3 X Dir etc.

Babyhex ran six motors from a single port with emc. Dave put pullup resistors on a couple of the extra pins that were used. Ray

Look at CNCPro http://www.yeagerautomation.com/ it uses one port for four axis. My setup is very different and uses a custom software for it's application. http://members.home.com/gregsdiversions My

What's your setup? Software, # axes, etc.? I think I heard MaxNC requires 2 ports for 4 axes, and I-LPT says the same.

I remember several people mentioning they're using old laptops to control their machines. I thought most step/dir systems needed one parallel port for every two axes. What do you do for three? Or,

I know my system uses one parallel port for four axis. I thought most did.

OK, it's done. 1. I found that how to do this is described in simple enough terms (even for me!) in the perlxstut manpage which is availabl

Have you looked into [incr Tcl]? It adds an object view to the essentially flat Tcl variable space and it's supported as a standard extension by Scriptics. See http://www.tcltk.com/itcl/ for an

Ron Ginger wrote about wanting to write a conversational programming interface in Perl. He wrote that the Visual Basic and Tcl/Tk data types are too limiting: ... Could be. The Tcl/Tk GUI for the EMC
