Post your code and then we may be able to tell you.

Check you have all the icons/screens in the correct directory within Mach3.

Hi Terry,

Yes many times, the 'O' codes have been disabled/removed 

They do not error out they are just ignored.

I once asked Art to activate them, his response was "to many problems with it".

General Mach Discussion / Re: Feed Rate

« on: March 27, 2008, 06:01:48 PM »

G90 tells mach3 to take all dimensions from one point eg the face of the part, G91 moves from the current position the said amount.

E.g.

G90 G00 X10. Z0
G01 Z-90 F100.
M30

Or

G90 G00 X10. Z0
G91
G01 Z-45. F100.
Z-45.
M30

Both bits of code will cut 90mm in the Z axis.

I have wanted to be able to do this for a long time, the problem is that not all the commands are supported in Mach3 IF, GOTO, WHILE, LOOP, etc are all missing and will probably never be added.

Without loops and comparisons it is impossible to convert all but the most basic macro.

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.
