I need to execute native VB code to get at some O/S functionsfrom within a macro. Mach functions in VB script only support Sendserial, and I will need to do a few more things like Getserial (made this name up), and discovery of the Windows available com port list. Has anyone out there done this? Any tips or instructions on how to proceed?

I've used a joystick as well as a game pad, configured with KeyGrabber and they both drifted on their own for some reason. I even brought one of the joysticks back to the store and exchanged for a new one, and it did the same thing after a week. It might be that I was just too cheap and didn't go with an expensive joystick

Check out www.homecnccontrol.com
Just what the doctor ordered.

I've just opened up a new shop for business, catering to the home cnc and small business machining markets. A while back, I was looking for an inexpensive MPG or pendant for my retrofitted mini-mill, but was dissapointed to find nothing offered in the home machinist price range, so I designed one myself. Art Fenerty was using one of these at the cnc workshop last month, and also discussed another one of our new products with several of the attendees. The Jog-Dial is in stock and ready to ship, and the Jog-Bot, a new style pendant that uses buttons like a stopwatch for axis selection, jogging, and OEM triggers is in development and near completion. There's a picture of both the MPG and the new pendant design in the products section - look here   


for more information.  Thanks for looking!

Parallel cables have 25 pin connectors on both ends. Depending on the type of cable, the pins you need may not  be wired through.  A printer cable is best since it will give you access to all the input and output pins you currently need with Mach.

No problem. I'm glad the pendant is working for you. I'm designing an MPG now to replace the keyboard, which will make this whole thing a moot issue for me. I'm using some inexpensive encoders. Let me know if you want to be kept informed on this.  I expect the whole thing will cost about $40. That's a whole lot cheaper than the devices out there today.

I checked out the GRex - looks like a nice piece of work, but I would worry about it at this early stage of distribution. One thing is obvious - it is very powerful, and flexible, which is not always a good thing in a new product. There seems to be a lot of control logic and programming of the microprocessor. The block diagram looks quite complex to me. I know the gecko folks have loads of great experience in this area, but there are so many moving parts between the control software and the board, and then the board and the servo or stepper control, that I have my doubts that this is going to be a hassle free path. It's clearly the "bleeding edge." Still, it is an intrigueing piece of technology.

No hurry. It's working on my system just fine. It's more of a curiosity at this point. If you get a chance - that'd be great. If not tonight - no big deal.

Did you get a chance to look at the code? I hope I didn't crash the system. Is there a way to pull it from the forum if it has a problem? I've been a professional software guy for over 30 years, but have not programmed in VB before. If I screwed something up - let me know so I don't do it again. The code seems very straight forward to me.

 :'( Rats!  I didn't mean to kill your system. I hate it when that happens. A thousand apologies to you, all your ancestors, and your present family!   I downloaded the same file to my machine to make sure I sent the correct .set and ran it on two separate computers. Try it again - you can always get back to a "good" system through the "load screens" dialog. It works for me. There's obviously something important different between us. I am honestly not sure what did it to you. When did it croak? I want to check it out so no-one else gets messed up. It'd sure suck to kill my system in the middle of a part.
