hi sorry for resurrecting an old thread. (this is the closest i can find to my issue) i have a boxford 250 cnc with 8 position tool turret, running mach3. i cant for the life of me get the atc to work, i am a complete novice as you can tell. i copied the macros from this thread. but i have a couple of questions: to run the macro m3000 i have saved it into my macros folder. so when i type m3000 in the mdi line i get a pop up for tool number. i type 1 for tool 1 and the macro just says done but nothing happens...
also when i set up the fixtures and tool offsets for t0101 thats fine and then i type t0303 the atc moves anticlockwise and works ok but if then type t0101 again it tries to move clockwise against the locking pin and looses position etc..
any help most greatly appreciated. thanks folks
my screen is attached and set up for the atc with the a axis

The macro should be named M6Start.m1s and placed in the macro folder of the profile you are using (Mach3Turn) or what ever you are using.

You need to set the A axis motor tuning so that if you type G91 A45 it moves 1 tool position.

The number is going to be:- number of steps per rev of motor X ratio of worm and wheel of turret.

I think the one I set up years ago was the smaller type and it was set as whole steps (1:1) and it worked out at 360 steps per degree.

The dro moves when I type g91 a45 but not the atc. However if I type g0 a45 it will move 45 degrees. But it will travel clockwise which is not good

OK, type G01 G91 A45 F250.

If it turns the wrong way you need to swap active hi/low on the A axis Dir Low Active in ports and pins.

hi thanks again for reply, im at work so will try tomorrow. its weird coz only sometimes it goes clockwise and others anticlockwise.
