    servo encoder signal as DRO in mach3

    Hi Guys,

    Please forgive me if this is in the the forum. I have just picked up an rf45 mill so i can make some chips at home. I have DRO's at my mills at work so this is something that i just can't live without.

    I could just add some glass scales and a dro but I would like to cnc the mill down the track.

    So, here is my question. If I add encoders that will be used when cnc'd with servo's to the x,y,z axis's and use the mill as a manual mill with handles, can MACH3 act as a traditional DRO when the encoders are wired to the host PC? The idea being that i can still have a usable mill whilst I save money for the other parts of the conversion.

    Thanks for your help

    Brad

    It may be possible to do this with Mach3 but there is a free option that works well with curbside grade computers. The software was written for DRO and it has features people expect from a DRO.
    DRO SOFTWARE

    Although I haven't got around to mounting encoders to the mill, I have tested the system and it works well. Ignore any mention of following errors in the link below, stepper motors can spin an encoder at speeds no human is going to duplicate without gear assistance

    The encoders came from here
    Digi-Key - 102-1307-ND (Manufacturer - AMT102-V KIT)
    Anyone who says "It only goes together one way" has no imagination.
