Yes, that would make sense, also the following error fix too ;)

Im still a bit grey though on function, you set the setter all the way down, does this position matter though - where is "all the way down" in reference to an R8 socket?

Yes i can see calling the Haimer 100 (etc) would be good, storing the height - but what height? Where is zero?

Would it be just the top edge of my fake R8 socket - touch that as home and zero the DRO then insert T100 (Haimer) set to zero on the dial and store the height?
Then insert other tools, read the height and store them?

If yes then its a little clearer - I am currently measuring offsets you are measuring heights - similar but not the same.

I let it go all the way down as that is a repeatable position to then zero the DRO (basically setting machine zero) That position never changes from day to day, so as long as you have a means to accurately repeat for the setting the DRO then you are fine.

Ah, making sense now, so its just a position that never changes and we call that zero, got it.

Looks like i have most of the bits in hand, also got some nice light 6mm GT belt and pulleys from the 3d printer junk box, the specs for the encoder look like it can take a radial load of over 3kg on the shaft so it should be able to support a pulley and a couple of feet of 6mm timing belt easily :)

I have asked CS-LABS about the motorless axis but i have a feeling it will quicker to just throw the encoder in there and try it out.

I think it would be good to not be using the G31 method if i can get all this stuff together :)

Looking good;)

Oh bum, never that simple is it.

Just reading the CSMIO manual and i see it states that the encoders must have differential inputs, this one has common outputs and they reckon it needs a signal converter?

Back to the drawing board :(

Hmmm, going out on a limb here but...

Does anyone know if there is a difference between the encoder inputs on the CSMIO-IP/A and the encoder inputs on the CSMIO-MPG units????

In the IP/A manual it states that connecting the A-/B- inputs on the differential inputs to ground for using a common cathode TTL encoder will result in distorted axis position, BUT in the MPG manual this is exactly what they show ????

So both units are differential input but one can take common encoder inputs and one can't ???

Or is that for an MPG it really doesn't matter that much and if so will it matter much for this task???

Why not just get a line driver and connect, will only cost a few £

Err, ok, whats a line driver?

Google time......

Thats the ones I used to turn the  Step/Dir signals from the ESS into differential for my servo drives.

Hmm, ok, thats looking interesting, does it need much/any supporting circuitry to make it all play?
