NOW if I can make it look the OLD way and do it the new way ???????

No problem - you revert to a previously mentioned scheme. You use your screen to load a table or whatever and your code operates on the table rather than on your DROs. In fact this is probably what you should do anyway - its good software engineering practice to keep a separation between the code and the interface.

HI IAN, Same subject but a different project(;-)

 We have a denford mill with a tool changer that is converted to MACH control. Now we have to interface the ATC (toolchanger) to mach. THe atc runs from a serial connection. We have captured all the control codes needed to run the ATC and can make the TC cycle by sending the codes through Hyperterm to the atc.

Question? How do we get VB to send the controls codes over the com port when needed?

Question Can I send a copy of the tool table to a printer port? Say LPT1

(;-) TP

see "sendserial" at http://www.machsupport.com/MachCustomizeWiki/index.php?title=Mach_specific_Subroutines/Functions_grouped_by_purpose or 4.4.10 in the customization guide.

Not sure I understand what you mean.

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

Graham.

Hi Graham - just so we don't get confused here - I take it you mean parallel port where you've written serial port. :)
Also - out of interest - what's the 9ms delay for?

Sorry Ian, its a reply to VMAX about his Denford ATC, I need to create a new thread, should not have hijacked this one.

Hi Graham, I had looked at the port command but being I am a double dummy I chose to NOT try that approach yet.
Thansk FOr the help, I am trying to get Richard up and running(;-)

Hi IAN, THe delay is to comply with the ATC requirement of a 9ms delay between charactors in the command string going to the ATC??? Yea I know weird but that is what it takes to work(;-)

I had tried using the SendSerial  VB command but I have yet to get it to work??? VB likes it but nothing ever shows up at the port(;-)

I THink I have also figured out that you cannot send anything to a printer from the MACH version of VB. I found my old copy of VB for Dummies but most of the stuff doesn't seem to work in" MACH "VB(;-(

Back to the drawing board, (;-) TP

Graham in the second line VB errors on the word BYTE.

This is a great topic. Stirling, Vmax, Poppabear, and Graham. It will have to work. I have admired all of your work for a long time.

Hi Stirling I almost missed your question. AS part of this project I would like to send a copy of the tool table AND a copy of the current slots assignment to a printer from a mach button. BUT it seems that the MACH VB does not support printing to an lpt port,at least not that I can get to work. It errors with,  not a supported object or command.
