    They look bigger on this tablet.
    so you've just got them on magnets, no actual guiding cup ?

    Ah ha - okay, also found the threaded m4 10mm ball bearings.

    okay under £5, altogether, for 12 threaded 10mm ball bearings and 12 magnetic cups :-)
    Bought m4 bolts yesterday as i found some really cheap t-slot nuts with m4 thread.

    Have to admit I like getting all these little packets from china.

    Currently thinking about a volcano hotend with 3:1 gearing - like what autowhiz uses. Not cheap, but I'd like to use my little nema 14 motors. Haven't tried one yet, might not need gearing.
    Struts should get here today.

    So with threads balls and magnetic cups - should work really well.

    that perspex on the carriages looks very thin and flexible. Is that a good idea ?

    10mm with a hole in the middle ?
    can't weigh more than a few grams.

    does it matter what the shafts weigh ?
    No idea what you've done (no pics ;-)
    I'm just thinking those magnetic cups on the effector and carriages and a ball each end of the shafts. Love the fact that i can just print a glueable insert to stick a 4mm bolt in and just screw the ball bearings on the end of the shafts.
    Much more secure than trying to attach complete ball bearings.

    I can cut the heads off the 4mm bolts with my bolt cutter dead easy. Tap that into a shaft insert, dab of superglue to lock the ball bearings in place - jobs a good one :-)

    Oh yeah, missed delivery guy - so struts getting here tomorrow.
    I'll ductape it together for a pic and to get some idea of the sheer size of the Big Bastard :-)

    Unless you're going up to a much larger nozzle size - can't see it making much difference.

    Got my struts:

    She going to be tall :-)


    30x30 seriously heavy duty feel to it.



    And standard 6mm t-slot nuts work just fine


    Corner pieces are going to be beasts, on reflection should probably have got longer horizontals.
    we'll see.

    Leg's improving slowly, so i can actually sit at the desk a bit longer each day.
    I think I'm just missing wheels and belt gears now, and all the stuff in transit from hong kong and china :-)

    as far as I know lol
    Any reason they shouldn't be ?
    IT was seriously well packed.
    They all line up and look perfectly straight.
    They didn't come from china - just about 30 miles down the road.

    I actually went for the lighter extrusion - but even that's seriously heavy duty, and about £20 cheaper.

    Bolt a couple spikes to the 415mm lengths and you've got a seriously heavy duty hand weapon.
    Lengths are all bang on for the shorter struts.

    like I said they look straight. line up with no obvious gaps.
    This isn't cheap chinese or american manufacturing - proper british engineering mate - they are straight ;-)

    so what am I supposed to do with these ?

    Plate is physically level - just 1, 100th of a mm difference between all three points.

    There is an autolevelling option on the printers control panel as well.

    But from what i can gather you have to move the head around manually and Ive never had much joy with that either :-)

    Okay i tried it once and seemed like a pita.
