I need to go KJN anyway to cut some more extrusion for the bed and they are going to drill/counterbore the extrusion I'm making the frame from. So I can bolt it together rather than use corners which is cheaper and stronger.
    Humm sounds good plan, I remember thinking at the time I should order an assortment and bang them on ebay, the price for T nuts is ridiculous in this country/online.

    When I finally finish my build I'm going to order 100 of each type for the 45 series extrusion for stock so I won't ever have to pay stupid prices again lol.

    When I finish my machine I will have used nearly all my extrusion up so need to go on a pikey mission round the scrap yards to see what I can find ;)

    Or just buy that machine I linked to if you don't first lol.

    Right bought a 13pcs collet set so I suppose I ought to get some endmills ordered open to suggestions, I want to be able to cut MDF accurately and I want some aluminium millers.

    I do know I will need ballnose end mill at least, I most confused on the size I should buy.

    Almost ready to have the aluminium plates made was going to send cad models and discovered that my clone rail has HR15 blocks not HG15 blocks!

    The difference is probably about 8mm in mounting height lol going to need to take some accurate measurement s and rethink the gantry as this is where the HR15 is going.

    the other choice is move some HG carriages across but worried the clone rail will be made of crap steel and proper HG carriages will wear it prematurely so think maybe I should stick with the original carriages for the clone rail.

    Once I have the mounts in pace I can finally start getting movement on the XY&Z axis ;)

    I may never have got on with my Prusa Mendel 3d printer but I could never have had even a chance at building this without it ;)

    Blue bits are aluminum plate to mount everything together, been through 3 different designs to solve the 15mm HIWIN/Ballscrew problem but happy with this one.

    Need to get some wiring for the stepper motor's as cables are far too short and need to be extended will something like this suffice?

    http://www.screwfix.com/p/time-round...FSIS0wodF9IDHA

    All my Nema 23's are 4 wire.

    Something like this would be better 4 core CY cable 1mm. https://www.cse-distributors.co.uk/c...creened-cable/

    How flexible is the CY cable? Will it be ok in energy chain? Thinking gantry and Z axis obviously. Seems cheap enough can get locally for £2.50 a metre (plus the dreaded) only need 6m's as max.

    No problem energy chain has been used many time by a lot of guys on here. The idea is to ground the screen and one end (control box) only.

    Thanks for the reply, when it comes to the spindle (I have a 2.2kw) should I use 2.5mm SY cable?
