Hello all, I been using Alphacam with Mach3 PP successively for some time . I use the 2010 screenset with Mach3 and 1 of the great features that comes with it is the ATC macro. I'm attempting to tweak/edit my PP so all works smoother together. I generated some Gcode from Alphacam using 3 different tools to help explain 2 things I'm trying to achieve.

The first I THINK I already accomplished... I removed the last line "G91 G28 Y0 Z0" in all operations except the last and replaced it with M5. I'm no programmer so hoping some1 could tell me if this could be a problem. I ran the code successively but held hand on Estop button the whole time.

The second thing is to remove the M6 in the first operation. It seems like anything I do in the PP doesn't stop the M6 from being written in any of the operations no less just 1. Is this possible to do without some complicated sub routine or at all?

Any info would be extremely appreciated.

Thank you, Email sent. I sent you the original unedited by me. Below are the sections I edited and seem ok. The M6 is being called in the Rapid Moves section "$20", what I cant figure out is how to write to remove it only in first operation.

Really appreciate your help,
Dan

Hello Marek, once again I apologize for not being more clear in first post of thread.

Below is Gcode generated from Alhpacam using your edited PP and the same sample geometry I used in first post. Its a square with 2 circles inside and I used 3 different tools to cut. Just removing the M6 from PP removes all M6 written for each operation. I need it removed just in the first operation, and need them in any additional operations. Its the M6 that starts the ATC auto zero macro. Programing skills and knowledge is needed to accomplish this and I don't have it.

Thanks very much for your help its extremely appreciated,
Dan

Hi,

In the $1000 section of the Post create a variable

FLAG_1 (6,0,0) '' Flag to enable/disable M6

In the $10 section at the beginning of the Post set FLAG_1 to 1

$LET FLAG_1 = 1

in the $80 section of the post do this

$IF FLAG_1 = 1
T[T]
$LET FLAG_1 = 0
$ELSE
T[T] M6
$ENDIF

or this

$IF FLAG_1 = 1
T[T]
$LET FLAG_1 = 0
$ELSEIF FLAG_1 = 0
T[T] M6
$ENDIF

With this FLAG_1 is set to 1 at the beginning of the Post so on the first tool call the output will be just T then Flag_1 is set to zero so on subsequent tool calls the output will be T1 M6

Hope this helps

Thanks so much Frank. Will post back results.

Works Great!!! Thanks again Frank.
