Combined Z axis reading

[DavidR8]

Hi @ycroosh , I have a PM30 style mill inbound. It has a quill DRO and I'm wondering if it's possible to combine that with a column scale to get a total Z axis movement.
I suspect that I won't be able to do this as the quill DRO is this style and likely has iGaging style output as compared to the glass/mag scale outputs.
No biggie if it can't be easily done.

Raising this question again.
I have a PM30 style mill but am replacing the factory Z axis DRO with a scale and reader along with a scale on the column. I know the adapter has four inputs. Can the quill DRO input be added to the column input to provide a total for the Z axis?

Sorry David, I somehow missed the original message.
All three linear axis readouts can show two summed up inputs. Summing "z" and "w" is very common. A bigger problem in your case is that the quill scale is of the 1.5V capacitive variety, and is not compatible with the glass/magnetic scale adapter.

No worries, I'm replacing the quill DRO with a magnetic scale so the input should be fine for TouchDRO adapter I have.

I also have a PM30 and would like to do the same thing.

Turns out that it’s in the manual

Hahah, the other details, scale and how you mounted it.

Oh sure. I’ll dig up the info when I’m on my computer
