Protecting vertical mounted DRO scale

[Ropata]

Hi Guy's

I have a few ideas of how to do this but I'm not too happy about them. Has anyone got a good idea or have done something successful to stop chips getting in a vertically mounted scale?

I mounted my Z-axis scale on the side of the base and put the read head on the back side which I figured was the best location for no chips. Mine also came with a sheet metal guard to protect the scale. Looks like you have a bit of a real estate issue on your mill to do the same unless it can move to the other side of the knee.

I don't see a really good way to guard yours in the current position.

Yes, yours seems to have a lot of flat clear space. The other side on mine has all the plumbing for coolant. I guess I'll make a fixed guard that will just have to be bulky.

I did my Z axis similar to Bruce's setup, except I ran the read head bracket under the scale. It was covered here:

Hope it helps.
