Hi Jasminder,

You could still use a DC motor and only need one switch running on a cam or an optical switch with a slotted disk.

You have to enable the A axis in Ports and Pins and then in Motor Tuning set the number of steps per one turret index. Actually just a bit more than one index so that it overshoots a bit and then reverses to lock.

Yes. The macro tells it to move the A axis. Go to General Config and under Tool Change select Automatic Tool Change.

Yes. Copy and paste it in the M6Start.m1s macro file.

one thing about the hellfire's turret i would like to know is that "does it has a worm and gear"? or just a stepper attached by some sort of reduction pulleys + timing belts?

regards,
Jasminder

You set it manually to the current tool and then you can check Persistent Tool Selection in General Config and Mach will remember the last tool on a restart. You can add a second switch for homing when you power up the machine.

Of course 4 switches on an 8 position turret would be better as Mach would always know the tool in position, but it's more complex too and requires 4 inputs, although you could even do it with only 3 switches.
