Hi,
I have to retrofit some old Biese Rover 7 which has boring head with 7 tool holders. These holders are mounted on the head and are pulled down/up by pneumatics via 7 control signals. I was wondering What is the best option for control this function by Mach3. Is there possibility to define tool change macro so it can output BCD Code to Outputs #4-6. Then I could build BCD to 7 segment decoder and so on, control 7 tools.
The second question is for feed override button. I have reed that there is possibility of connecting encoder directly to LPT port, and enabling this function?

Cheers

The best way to do the FRO in your case is to use a ModIO . this will also giveyou the IO that you need for this project

Yes you can write a macro in the M6 to change tools and set the offsets... there are a few guys that will write the code for you for a $$$  and if they can't do it I can have a look at it... OR you can post here and we will teach you a bit of VB (not much fun but gives you the power )

Hope that helps
Brian

Thanks Brian.
 I would like to play a little bit with VB, as i am closed to C++ and assembler, so i think that it wouldn't be a problem. ModIO is my definite choice, but i have to do in next few days, and w/o it this time.
Cheers
