VB and the development of wizards / Re: Tool changer routine with hot swap

« on: March 27, 2008, 05:22:02 AM »

was not thinking when I typed it in, Byte is a reserved word in VB, try it like this :-

Dim command As String
Dim oneByte As String
command="B000013E------"
For a=1 To Len(command)
  oneByte=Mid(command,a,1)
  putportbyte(Ox378,Asc(oneByte)) ' Ox378 is the address of your serial port
  For b=1 To 1000
  ' this is a delay loop, adjust to get your 9 ms delay
  Next
Next
End

Hi Terry,

something like this will do it :-

dim command as string
dim byte as string
command="B000013E------"
for a=1 to len(command)
  byte=mid(command,a,1)
  putportbyte(Ox378,asc(byte)) ' Ox378 is the address of your serial port
  for b=1 to 1000
  ' this is a delay loop, adjust to get your 9 ms delay
  next
next
end

OK, if you had to centre, drill and tap 4 hole you could use a sub for the hole positions like this.

I think Scott (Poppabear) has one that works that way.

You have to start the G41 on the first feed move. Rapid moves vector so the start point is wrong.

You can reverse the direction by setting the X & Y scale to -1, beware that everything will be reversed.

You can put G51 in the program to reverse sections and then G50 to revert to normal.

Man you are making my grey matter work overtime.

You need to contact the supplier of the interface and get the pin outs for the M108, it may not work the same way as Mach3.

You may have to set the pins different and also 1 pin may be an enable signal.

If you look at the settings page you will see the pulley number in use, it is the correct one?
