    Hi
    :eek: DSC02528.jpg DSC02526.JPG
    Hope i can get help today!

    Im building a 1500x1000mm OX CNC

    Im pretty good so far until i reached the part adding the 8MM Rod to the nema 23 i didnt know it had a 10mm collar on it?

    so the adapters i have dont fit?

    Will i be better to buy a NEW 10mm Acne Rod? or buy a new adapter 100mm-8mm Shaft Coupling?

    "Just Thought" i cant use a new 10mm Rod as all the other coupling wont fit on that! Dam it!

    So is the only way now is to order? a NEW 10mm-8mm Shaft Coupling or buy a new Nema 23 8mm Shadt motor?

    Only experts advise please?

    Will my other Nema 23 10mm Motors be okay??? as already assembled?

    You will need a 10mm to 8mm coupling on all your motors and rods if they are the same.

    thanks Master Gray!

    Billicks!

    Ive just checked and see the GT3 Pulleys needed are 8mm also

    Which means i will need to order another 4 x Nema 23 8MM Rod motors, as all the ones i have are 10mm :(

    OH DEAR! So anyone else reads this for the OX CNC make sure you get 8mm Nema23 AND NOT THE 10MM Nema23
