    Barry, im going to have the cables from the steppers coming in to the control cabinet and earth them to the star point and the cables from the drivers are also earthed at the star point. They connect via the din terminals. I'm also contemplating having a junction box on the machine and wiring to that and then the motors etc....

    I made a few on the 3d printer but they take quite a few hours each. But since then I have made them on the mill. I have made them with various plastics and also the reconstituted rubber from tyres that they seem to make decking and posts out of but that is full of crap and holes.
    .
    On the mil they take about 20 min with the tool changes once setup. For the undercut I use a T-slot cutter.
    .
    The order in the way I do it is from the solid drill the 4 holes then reduce the block down, hollow out the centre, profile the outside, do the undercut then turn the piece over in the vice then cut the bottom off to release the part. Then put it back in the vice to profile the gland hole out. This was all done from a dxf file with Vetric Aspire ..Clive

    edit Tool used 6mm endmill, T-slot cutter and drill.

    Here is a link to buy them http://www.soigeneris.com/nema_23_st...r-details.aspx but you would need to check carefully if they fit

    I think you are fine with the earthing effectively earthed part way down the cable as long as you don't make a loop ie earth both ends. I don't think it is a good idea with the junction box on the router in my humble opinion what is the point in chopping a perfectly good cable and then putting a join in it. ..Clive

    Well to start with the router will be floor mounted until I make the frame for it to live in vertically (at the rate I'm going that'll be months...)....so I was thinking to save having cables longer than I need dangling everywhere until it's finally sited I'd have a JB and when it's in its final position adjust the cables to suit....

    Ah I now remember you are going to mount it vertical. But you will still have to have the continuity of the screens in the JB. ..Clive

    The advert says they're for 57mm motors, not 60mm, so yes... be cautious.

    Still umming and arring about the JB, makes it a more modular solution but then gives more scope to introduce areas that could cause problems....

    I think I'll make some myself when the machine is up and running, although it'll be tight for the Z axis motor as it's quite near the plate.....and I've got a Nema 34 on the X axis......

    OK so today I'm back on the limit switches. Below is the diagram I currently have, is there a way using the relay that I can have seperate inputs from each limit switch or is it not needed?

    I'm going to have travelling switches on each axis (apart from the Z where I can probably get away with fixing it and have the trigger points on each end of the Z axis) and wire them back in shielded 3 core cable...

    The home switches I'm going to wire individually into the CSMIO IP-M.....
