First cuts went very well!!!

Here is the roughing step in rigid foam..

Impressive planning and execution. Way to go. I hope you post more vids. Were there any problems that you ran into that you may want to share with a noobie like me?

I didn't really run into a lot of problems.. One major suggestion I'd have is to go with 1/2" lead screws... I went with 5/8"-8 2 start (4 TPI). There is huge support for 1/2" Like the dumpster nuts etc... not so much for the 5/8".

Start smaller than I did. My thinking was that my gantry would look the same for a 48" table as it would for a 96" table... why save the 20$ in MDF and $50 in lead screw? I am glad I have the working area, but I am already working on revisions and a smaller table design.

Take the addage that 'no one builds only one table' as fact... Your first hobby cnc is where you learn how to build your second cnc. Select components that you could eventually transfer to version 2.

Good luck on your build!!

Very nice workmanship on your machine. You spent considerable effort in the finishing of the MDF parts. Is that satin polyurethane with no stain? Clean looking machine design as well. Congrats.

Thanks!!! About 3 coats of satin polyurethane sanded with 220 between coats...

I thought so. It looked familiar. It's exactly what I did on the two 4'x8' MDF tops of the work tables I recently built for my workshop. Even used the 220 grit sandpaper.

Awsome machine and I love the renders too, such a nice project overall. If you ever decided to release the plans to the public, please let me know as I would love to have a go at building one of these.

Cheers

Very impressive! I started planning my own machine recently and was wondering if you are using a 8' lead screw for the length of the table?

If so, where did you get it?

Having the models available at McMaster is great. Thanks for the info!

I think the screw is 100" I ordered it from Roton.com. This is also where I picked up all of the nuts etc.. Consider a bit more beefy lead screw for this kind of span, although my 5/8" diameter screw does just fine.

Good luck with your build!
