Bridgeport Series 1 Interact. Refit/update . Opinions please.

Hi, really glad to find this thread as I'm currently planning to swap out the motors on my non working Interact 1 series 2. I see the problem with the short shaft lenghts on these new Chinese servo motors. What route did you go? I was thinking of making shaft extensions something like this and re-using the 12t stock pulley but would the over hang be too much? Cheers Ross

Hi. for X and Y I used Panasonics with standard shaft but its not great. For the Z, I used the next motor up (1KW Panasonic, overkill) for the additional shaft length.

Suppose if you can get the shafts with a good tolerance and some grubs, it would be OK.

Panasonics, what are they? Are they extensions.

No, Panasonic (the brand). For example - https://www3.panasonic.biz/ac/ae/mot...o/a5/index.jsp

Dooh! I get it now :)
