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

Err, ok, whats a line driver?

Google time......

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???

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

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;)

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 think the big issue is - will the CSMIO allow me to have an axis with an encoder but NO motor on it without throwing a hissy fit?

As i said before - probably not when out of reset due to ePid fault BUT I only need it when IN reset

Obviously would have to make sure Mach did not include that axis in Ref-All.

Hmm, I don't think I'm that far off the mark really, my major omission is that i don't record the length of the hammer as a tool, i use (or tried) tool zero.

So basically, if i can get the encoder into a Mach DRO, it should all be do-able?

What do you do when say a tool needs replacing etc - whats the sequence then?

I might be a nautical mile off target here, its Friday after all:) but as i see it, to make this work I would need the mechanical axis linked to an encoder. That encoder only needs to be calibrated to show mm in a screen DRO in Mach3??

Then I would place the Haimer in a turned dummy R8 socket, place the head on the Haimer and zero the DRO, replace with a tool and the DRO would now show the offset?

Maybe too simple or am i missing the point here?
