Hi all,

I'm building a small CNC mill and trying to figure out how to program sheetcam to tell Mach3 I want to change from a roughing tool to a finish tool?

I have a toolpath set in SC and it all looks good, I've left a finishing allowance etc.

I presume I need to program a code snippet to tell Mach3 I want to do a manual tool change as the tool holder is a collet and all tools will be referenced to zero every change so i'm not using the tool table etc. - all entries are zero in the TT

Then I presume I need to create another operation in SC to run the finish pass on the new tool???

Of course I may be totally wrong here

If right, what code tells Mach to stop and wait for run start?

Ignore this question, I've just re-read my code and sheet cam takes care of it by moving to a programmed position and calling M6 T1, 2 etc so as long as my tool table is empty it should be ok.

I scanned the code and missed the tool change bit first time round thats why it didn't make sense, found it with a search

Test running it in my laptop setup of Mach3 gives exactly the desired effect
