    But do these Chinese controllers your looking at output Analog signals or just Step/Dir.? . . . Most I've seen are Step/Dir.

    If was me and DC Servos/drives are working fine then I'd just go with the Cslab's IP-A. Doesn't get any easier just little rewiring and away you go and with top notch controller from Top company.

    This type of upgrade is a no brainer, like Dean suggested. Everything could be ripped out and rewired in a day.. ~700 euro but you keep the good motors you have. Final result- a modern machine that will do 3d, 4rth axis and so on. Which otherwise could cost arm and leg. Then you could fit a stepper if you like for the additional axis.

    He needs the Cslab's IP-A for those Dc motors but can that do step and direction for the 4th axis ?

    Nope it can't and you bloodly well now it can't you old Git. . . . . Anyway 4th axis wasn't mentioned when I suggetsed that route.

    To be totally honest (and think John S would agree) if it's working OK I wouldn't touch I'd just sell it and retro fit an Old VMC.!!

    Nope, genuine query as I have never used the CS Labs gear and some of the Chinese controllers can do 0 -10v and step and direction.

    Personally if it were mine I'd go the IP-A route as I'd not thought of that solution.

    Anyway less of the Git .

  6. Servos are +/-10V not 0-10V.
    0-10V are typically for speed control for spindle and these controllers.
    I have a few stand alone controllers from China and they are all step and direction.
    Not seen one that is fully closed loop with the encoders going back to the controller, so if you know of one, can you link it?

    Also there are stepper drivers that will accept +/-10V as well, so if you need another axis on the CSMIO/IP-A you can use a stepper motor, but it needs to be closed loop with an encoder fitted, so will not be much lower price than a servo.

    Can still rig up a servo on analogue via belt drive to actuate the 4th if going the IP/A route surely?

    Well I've not seen any, well any that are affordable anyway. Likes of your Siemans etc may well but they are very expensive. Also think you mean +/-10v not 0-10v different animal.

    Yes course can if got spare axis but John asked if IP-A could output Step/dir as well which it can't.

    With a KFlop & Kanalog it's possible to use both +/-10V and step/dir, however to use the step/dir outputs you have to sacrifice Kanalog encoder inputs.
