    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.

    I did try attaching the PDF, but I think it's too big for the forum to accept :-/
    Ok I agree with M_C try setting parameter (P2) 29 to = 80. This is 320 / 4

    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 !
