    Not sure if this will work but I've just created a 3D PDF of the router which I'll try to attach...I know I've not done the 50x25 cross members yet...or put things like steppers, ballscrews etc but it's just the basic frame and gantry.

    Well it worked for me. I didn't know PDF's could do that, I must investigate more. The rendering is as good as you get in something like SolidWorks. The design is looking good and really coming on a pace now.

    I've not played with the clours and rendering yet, will do if I get time. We've bought an add on that means you can make animations, can't wait to install that and have a play with it (bought it to do work animations for our new web site that we're currently designing)

    Again cheers, just doing the dimensioned drawings for the pieces now so I can start the machining...looking forward to that!

    Set up a straight edge parallel to the master rail 300mm away and put a DTI on a carriage and moved it up and down the rail. There's about 0.25mm of twist/dip mostly near the rear of the machine.

    Only conclusion I can accurately draw however is that my DTI is too cheap as it moves all over the place i.e. doesn't return to zero after going up and down a few times...need a better quality DTI....

    Any thoughts on what might have caused this? I'm still experimenting with my machine and epoxy but it's been too cold in my garage lately to pour any more. Took the old epoxy off this afternoon and shall shortly be trying a slightly different technique.

    I'm going to check the rail for bow/dip tomorrow with the straight edge to see if it's that. If it is then ill shim the rail where it's twisted if I can.

    Looking at the rail today I put the straight edge on the rail and tried the feeler. There's a dip at both ends (last 6 inch) of the rail so ill have to shim that before carrying on much further :(

    Not done much else on the machining as been making a tapping arm today...

    Needed some 20mm aluminium for a clamp for the pantograph arm I'm making at work so put the big plate I've got on a table and used the Evolution circular saw to cut the plate to size for the bed. The 100mm strip cut off will be used for blocks for mounting the ballscrew mounts on etc...
