Thank you for taking the time to do the detailed videos, I am three steps behind you in the assembly of my CRP4848 but I now watch your video of each step before I proceed as there are some great tips.

I am impressed with how well engineered and complete the kits are from CNC Router Parts and accuracy that is emerging during the build.

Cheers

Great tips in your videos. It'll be a huge help for helping me with my own build.

I hope you continue with this thread right up through your first cuts. As you can see, you have a bunch of interested followers.

I recently purchased one of these kits and while I haven't gotten all the parts yet, I greatly appreciate these videos, because I'm still a bit intimidated at the prospect of assembling one of these. I'm sure these videos will help. I'd also love to see how you fine tune the machine after it's all assembled and running!

Yes yes, please keep the vids coming!! We are all loving this!!

I just want to say Thank You, to everyone that left comments, it is appreciated. I am glad that so far my post's are helping those that are building, going to build, or are thinking about building one of these machines. I plan to keep going with posts beyond the first cuts to show what this machine can do. My best to everyone.

For the Z-Axis, I locked the Heli-Coil onto the lead screw and remove the bearing/screw assembly. I then took the Lead Screw Nut and ran it up the lead screw to snug up the thrust bearings and tightened the Locking Collar around the lead screw. I the reassembled everything and removed the motor. Next slide the Z-Axis between the upper bearings on the Z/Y Plate and gently screw into the Lead Screw Nut. Turn the lead screw until you get it through the bottom bearings. Then tension the carriage bolts and clamp the carriages together. Finally tighten the bolts to the carriage. Last mount the motor and tighten the Heli-Coil to the motor shaft. The pictures show the final Z-Axis and the R&P components.

I am also building the 4x4, and while i didnt find this until I finished today, it has some great tips to get around some of the issues I hit as well. I also suspect my somewhat more lax attention to intense squareness will hit me later. I am getting started on the electronics in a couple days and look forward to seeing how you pull it all together.
thanks for sharing in such detail!

Where did you get your motors and drivers from? what supplier?

The rack clamps start flush with the front of the machine, the back clamp ends at 54" from the front and the other 2 are 14" from each other between all of them. For the Spindle Mount I used 1/8" x 1/2" steel plate and cut 2 pieces at 3" in length. Drill 2 holes in each 1-1/2" apart and tapped 5/16-18 treads to make nut plate. The bolts are Socket Head Cap Screws 5/16-18 by .500 long for the Mount.
