Brains Development / Update DRO from Modbus

« on: October 20, 2008, 08:49:16 PM »

I programmed a PIC chip to be a mini ModBus and it seems to be working great

I created a little VB script to step thru to see how it's doing and it does just what I want, It  inputs 64,65,66,67 and assign's the correct values to the variables.
As you can see from the script I have a DRO assigned 1010 that it displays the XaxisRegister and it does that all correctly.

TabletXaxisPos = GetInput(64)/1000
TabletYaxisPos = GetInput(65)/1000
ButtonValue    = GetInput(66)
FlagValue      = GetInput(66)
SetOemDRO(1010,TabletXaxisPos)

All of the script works fine!!!

I am trying to write a brain to automatically update the DRO instead of a macropump and I'm not having any luck.

My brain shows MOD:4-P:64     Formula = A/1000     OEMDRO:1010    I divide by 1000 to scale the 0 to 12000 input to inches

My Mod bus is Address 01  and its the first 4 registers.  I must be doing something wrong in the Mod bus definition somewhere but can't see it.

I'm trying to display my Graphics Tablet on the Screen

VB and the development of wizards / Loading Code from another program

« on: September 20, 2008, 10:35:14 PM »

I am going to write a small program in Visual basic to take position data from an old graphics tablet and convert it directly to G-code to cut small pieces of
metal on my Plasma cutter.

What is the easiest way to automatically download the new file directly to Mach3.  I could make it so it would act like notepad and accept the file and when modified download
it back to Mach3,  I need Mach 3 to call the program with a different file name each time and I'm not sure how to do that with the OEM call.

If I need to use the SDK ok but I'm pretty green at VB programing and especially about DLL's etc.

Any help on a wizard or Script would be greatly appreciated
