Thor, or should that be Zeus?

What probe did you buy?

One thing you'll need to check, is what voltage/current the probe is designed to work with. I made up a small interface board for my probe, so it was only switching the designed 5V, so I could use it to switch a 24V opto.

Two of these, almost a year ago, lol.

So Ive bit the bullet and bought a 'proper' probe. Its mechanical, not electrical and I want to make an arm for it like the Datron has that comes down, probes and I can then move it back in the 'up' position when not needed. Thinking to use some form of offsets to make this work.

How do I manage with an arm to rotate 180 degrees? Arduino Uno and servo? Id need a fairly strong servo me thinks ....

Thoughts?

Do you think it is possible to rotate about a hole/pin and get the repeatability ? How about sliding the arm up and down with a piece of spring steel to hold it against a ground edge? Could have a slot in the middle with a fixed dowel pin to give top and bottom end stops. Then add detents for top and bottom position. Manually move it up and down as required or drive it via a motor with a cam?

Well, I'm bad with this type of thinking. Datron have this on their machines (it pivots 180 down), so there must be a way but im not against it going up / down instead, anything I can look at on Youtube for inspiration?

So Thor has had a bit of an upgrade / make over.

Spot the difference.

Go on Chaz give us a clue

On another note what is the max spindle speed and a link to it would be nice.

**Desertboy** · 12-10-2017

I know the answer but you told me lol having seen Thor though I could have spotted it anyway ;)

Congrats ;)

Its an HSD ES909. 6.8KW 24K RPM with ISO 30 tool holding. Small issue to actually power it but working on that. It runs happily off 220V, even though its a 380V unit. I cant get to the wiring to Delta the motor (these came as options for both voltages) so I'm hoping that I can run off 220V for now. It has two thermisotors which will trip if it gets too hot. I dont need to cut at 6 KW, even at 2KW im removing a fair bit of material and I now have an tool changer. Buying balanced ISO 30 holders is pricy but will build up a collection once I am happy that this works reliably.

A quick test cut. Looks like Ill be ordering more tool holders. Happy with the initial results. My Z is fairly heavy however (As predicted), might need to look at changing the gearing on both X and Z axis now.
