Apologies if this has been asked before, but are there plugins or wizards for Machturn that support probing and toolsetting please?

RFA: I have developed a method to sense when a tool touches a (stationary) workpiece, for example on its periphery or end and also to measure the eccentricity using several readings.  I want to use this to sense the relative position of a piece of stock of known diameter in the chuck so that the DROs can be automatically set.  I have in mind a routine that could be run that would slowly move the tool until it touches the workpiece then stops and updates the DRO setting.

I'd like to modify an existing program rather than start from scratch, so it would be useful to know if anything is already out there.  At least some guidance - would this be a macro or a wizard please?

Once I've proved it works I'll also post details of the sensing method.

Wondering why you would want to go to all that bother. All you need for Turn is an accurate X axis home switch. I use a proximity sensor and get better repeatability on my small lathe than I did on a Clausing Storm 200 lathe with Fanuc control. Just set all the tools one time this way. No setting required, just home the machine, set your Z axis zero off the stock you just loaded and start machining.

Well, that's a good point, but my reasons are several.  First, this effectively provides an accurate X axis home switch which is needed for setting up the tools in the first place.  Second because I want to measure eccentricity.  Third because I'm fitting the same system to my mill(s).

You would be better off just starting from scratch and creating whatever it is you need.

Just a thought,(;-) TP

Would you care to share what proximity switches you're using and where they can be purchased?

Thanks,

Kerry, not just yet!  It's a technique I'm developing which isn't proven yet.  When it is I'll post details.
