I ended up swapping out the rails as well. I ditched the makerfoot things and went with 20X40 makerslide, sandwiched with another 20X40 extrusion, then used the midspan support kit to support the middle of the rail. I found that by doing this I was able to get the table squared perfect, with the previous setup it was just slightly off due to running the makerfoot the full length of the table. I also changed my end brackets to 1/4" carbon structure plate. Way overkill but supports everything without any flex. I've said a couple times I need to update the post, I have time this weekend to document and show what changes have been made and will get them posted to share with everyone.

Thanks AFK66, really no rush, I'm going to install my belt drive on my existing z-axis and go from there. I'd like a beefier setup but frankly I can't justify it right now.

So I finally caught myself machining something and figured I'd record a video on my phone, quality isn't good. I'll eventually get some better quality videos cutting larger stuff. But I guess it's the thought that counts, right??

1/8" acrylic cut in a single pass, with a 1/16" thermoplastic bit from precise bits. Feed is at 16 IPM, first attempt at cutting something in a single pass, I was able to speed things up to 25 ipm without issue or noticeable bit marks on the material.

Couple of updates,

I'm in the process of switching to 15mm GT2, 3mm pitch belts. My 276 oz nema 23's seem to be a bit much for the smaller GT2 2mm belts. I should have those mounted and up and running this weekend. A month or so ago I also switched to a Routakit HD Z axis, and X plates with the additional motor plate for mounting the belts on the back side of the gantry. This upgrade was far better suited for the heavy spindle and I must say it's been amazing so far. It's a really well thought out design and has been seamless to switch to.

Now that I have everything back together, I have just a little more work to do to my table top, currently it's just 80X20 extrusion spaced out roughly 7" apart from a center 20X20 extrusion. I plan to run MDF strips in between the extrusions to finish up the top. Going this route I was able to one use extrusions I had, and also cut the cost down on the top.

I'm really happy with my setup, and am very thankful for the forum and the wealth of information and people who have made this project really come to life. Big thanks to Louis V for his countless answers and help along the way.

Curious, was the deflection in the z-axis or really more in the x-axis? I'm looking at making a new x-axis to better handle the loads of a Dewalt 611 (about the same power as the Ugra CNC spindle, though obviously not as nice!).

Sorry for the late reply, yes I'd say the x-axis was were I saw deflection. Switching to the 80X80 setup helped tons, it was paired with the routakit HD Z-axis. The combo of the two have been extremely reliable and worth the investment.
