Alan, That's not such a bad idea used in combination with Gene's idea of 3D printing. I don't think this stepper motor will get very warm but generally mounting a stepper onto PLA is never a good idea since it gets soft at a low temperature.
But maybe using ABS would match the temperature spec of the plastic base used by CUI. Then essentially build two ears that reach the outer mounting holes and match the curves on the ears of the CUI mount. Connect the two with JB-Weld over a linear distance of an inch or so. I'll give that some thought too.

I just used clay to build a dam around the area that I wanted to fill with epoxy. Then after setting I drilled and tapped the new support. It was much stronger than the original part.

Easier to just order a new motor perhaps. > John _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
