Most of my time belongs to my 13 months young daughter so I'm not playing with this machine much. Only about an hour a day. I'm going slow but steady tough.

Once the machine is ready to cut I'll cut a third spindle bracket for more rigidity.
Very nice. Thanks for showing the progress.
OK I admit that I failed on the X ball rod end. The BK12 block is too large causing to push the stepper about 70mm out. That's too much. I had to put the BK12 inside the gantry but in vertical line because when I install it inside horizontally (as it is) it touches the Z assembly.
As I solution I will make a FK12 like block. Will post the progress here.
I don't know if you have looked on Mcmaster Carr but they have a wide selection of level options, having said that with that much weight I would not recommend castors. Castors to move it but once its moved set it on leveling jacks or castors. McMaster-Carr On a side note I put moving dollies under my cnc to move it, it weights around 1200 lbs...
Looking Good.

I agree with Bryan; you don't want to operate a machine like that when it's standing on casters, even if they do have brakes. A solution I've seen, for machines that need to move, is a combination of casters and adjustable feet that retract on heavy screws. You roll it to where it needs to be, then crank on the feet screws until it's level, and the casters are dangling in the air.
OK let's continue with the FK12 build.
More pics tomorrow...
Looking good.
But isn't the z to x axis plate still mounted upside down? It is costing you several inches of z-axis clearance.
I think we are not seeing the same thing.
I am looking at this where the z-axis support plate hangs down below the gantry.
Flipping that plate over should let you do this.
The plate can't be flipped because the mounting holes of the lead screw block wont get aligned.
The Z is in the lower side because I only have 100mm Z axis movement (small and short old rails). When I upgrade the Z with longer and bigger linear rails the whole assembly will be moved upwards as you suggested.
Thanks for your interest.
Got it!
I didn't realize you were going to eventually upgrade to longer rails.
Just a little more work to finish this.
Nice work and wonderful thread to read and see!
Very inspiring! Thanks for posting all the pictures for us to see.

Thanks Leo.

OK I just finished the ball screw end support. It was a mile stone to finish the CNC. Small project but I really enjoyed it.
That thing is really nice. I'm playing with it like a child.
Just finished the the opposite lead screw end support. Also installed grease nipples to the lead screw ball nuts.
