Sizing Dro Scales on Sieg sx2 Plus

<< < (2/3) > >>

mc:
150mm for the reader head length seems excessive.

What scales are you looking at?

There are various options depending on how much space you have available.

chipenter:
I made my mounts the same size as the table on my X1 that has the same table .

Buell:
My plan was to use the Glass scales. approx £170.00 all in 3 scales and a Dro display gives you all the whistles and bells...circle diameter with holes set ..points to go back to and many other. I guessed if i was to spend £100 on cheap stuff i may as well go large and give my self a fighting chance of doing some of the other things i may find myself wanting to do in the Future. They have i guessed a small level of glass in them so Not very adaptable ! but yes i think i will go for as near as the same length as each axis..Thought if i go for the 500mm for z Then if I ever take it off and get a bigger machine may have the chance to use in one other location !

Buell:
something like these ?

Those are the more common size of optical encoders, but you can also get a slimmer version, which can be handy especially on the Y-axis where mounting space can be at a premium.

I'll send you a PM with some details.
