CNC Rotary table/lathe head indexing

[irving2008]

Nipper,

Welcome. I'm sure Steve will be along sometime to answer this but my 2p (or should that be 2c) worth for Q1 is that, yes it could, but its overkill since you don't need the complexity of a fully variable positioning, you need a 'rotate to position x'. The hardware would be similar but it would need different software. If I was doing it i would put some positive position indication, or even tool type indication as feed back (replacing the keypad effectively) so that you can have 'position to parting tool', 'position to facing tool' type commands irrespective of where the tool was in the toolpost.

As to Q2, I know Steve has said he doesn't do these pre-built in the past, but I'm sure there are people in your part of the world who could help you there...

Hi Nipper,

It's pretty much as irving2008 says. You could use the divider but it's overkill for a toolpost, also it raises the question of how do you make the whole thing 'stiff' enough to work properly? If it's for a fully automated system then you need a method for locking it down and if not then I think you'd be better with a manual indexing toolpost.

Regards
Steve.

I think auto-toolchangers have a locking plunger with a solenoid or stepper driven retractor to lock the post and a switch to indicate the plunger is clear so that the software wont turn the post until it unlocked. A switch to show the locked position would also be useful.

The watch dog timer isn't used in the firmware - so if you're enabling it then that's why it's resetting!
