Confused again!

So I've had a little play and its still not playing ball but its hotter than the sun in my garage at the moment and il have wait until its cooler then hit it.
By memory in the Fanuc manual the numerator and denominator are used for gear reduction and in the Adtech the manual states :

" When screws of different pitches and motors of different step angles or servo motors of different pulses are matched or connected through gears it allows keeping the program and actual motion distance consistent through electronic gear ratio setting of the system. "

So I've thought this meant by the first part of the statement that the motors and pitch ( with the calculation ) would be needed for the setup but you could also read into the second part , that this setting is for gearing the motion . Even reading Fanuc manuals usually leaves you scratching your head if you overthink the use of English and this manual is no better.
With the quick go the 1/1 its not even close to measurement and 1600/320 was interesting until it didn't move at all , but i need to get in and play more when cooler and have another scan through the manual .
Thanks

That's about what I would expect with using steppers because the Encoder parameters will be much higher, probably something like 2500 by default, which is a standard Encoder base count. This could also easily be x4 because encoders are quadrature and it probably uses the base pulse rate.

If you can point me to the manual I'll take a look.

Jazz, YGM (or you should have, unless it's gets bounced back for being too big!)

Cheers M i'll take a look later.

I changed the 2-29 to 80 and the Num / Denom to 1/1 and no change still out but I'm going to have a look when I've got time at the weekend .
So just for interest I found a blog with a guy setting up a Newker control , cant believe it much different and he's setting up a 4th axis with a stepper motor

https://mightyshiz.blogspot.com/2018...ewker-cnc.html

He says :

"The units are important too. I have 2000 steps per turn set up on the stepper driver and the controller seems to generate 4 pulses per "step", so I need 8000 on the numerator and 1900 on the denominator (# in "axis" parameters). Not clear quite how all that works but certainly, the indicated units for the A axis correspond with degrees movement on the table."

Now i haven't got into reading too much yet but it was interesting that he's got the big numbers in numerator and denominator rather than the 1/1 .
So I'm going to bash google as I cant be the only muppet running one of these with steppers ......or can I .....hmmm!
Thanks

Some guy called Muzzer ?? .....now where have I seen that name before !
