Steel framed fixed gantry draw slide build super cheap

[Steel]

Made some progress on the build i got the y axis hooked up to the lead screw but that was about it.

Also found all is not what it seems with my BK12 fixed end blocks i brought as part of a kit off ebay
no angular contact bearings here just plain old 6001z's

[Steel]

After many emails with the ebay seller I was given 6 angular contact bearings for the BK12 blocks,
That should be a lesson for anyone buying BK blocks always ask the seller what bearings there fitted
with before you buy !!

Today i got around to fitting the lead screw for the z axis, i made the bearing holder and fitted it with a
3200-2rs that should take care of any axial load..I have also fitted a nut with grub screw to add preload

I decided to go belt drive so i can mount the stepper and not have it sticking up in the air.

OK well screw the draw slide idea this is my current build ...

Much better way to go, just need to do the same on the Z axis now. How you driving the X & Y axis?

[Steel]

Y axis will be driven by 1605 ballscrew and since its a 2 motor x axis ill drive it with 16mm trapezoidal thread since i have a meter spare and, im going try the z axis first before i make any changes see if it holds up to cutting wood. I did the layout like i did because i can make cuts 800 high and 400 wide just in case i wanted to make letters for signs or make one very long sign with this design there's no limit to sign length just height.

Coming along, its been noted before about the bearings being less than what they should be.

If anyone needs some these are really nice: http://www.ebay.co.uk/itm/360612149297

Ignore the pic as what turns up are very nice high quality bearings.
