Air blast during probing: yea or nay?

[trochoidalpath]

I was running a bunch of Delrin the other day and the long, stringy chips made quite a mess around my probe and tool setter. Made me wonder: any disadvantages to running the air blast during the entire tool touch-off and probing cycles?

It's pretty obvious how to modify the canned touch-off routine on the Speedio to do it. But I was wondering if there's some reason why it's a bad idea.

No disadvantage that I'm aware of. I have done this and seen it done fairly often.

It could hypothetically trigger the probe but I've never seen it happen. We use air blast on most probing cycles.

One thing you may run into depending on how the tech configured the air blast: mine was one a "one-shot" M Code that activated the blast for a set period of time. You can mode it to a modal M Code (it will register e.g. M438 on and M439 off) and will have to modify the macros to turn it on and then off later on.

I think gkoenig mentioned modifying his to have the blast on the entire time during the fast touch, and then turn off for the slow touch. Seems reasonable.

Is the probe sealed enough to resist chips & coolant blasted at it ?
