New Machine Build- Slides work very well.

[Drools]

I have been lurking and asking questions for a few month and collecting parts. Here is what I have done so far. The electronics are built but just not mounted. I have new 270oz motors and bearing blocks to go with them. There is still quite a few things to do but I'm plugging along.
Comments are welcome.

where did you get and who cut the 80/20?

[Drools]

I got the 80/20 surplus on E-Bay, with 2 angle brackets and 1 package of 50 x 3320(used) for 200.00US. I got it in 6 pieces each 4ft long. Originally I was going to purchase a non-ferrous metal blade for my mitre saw but after asking around I was able to get it cut at a local machine shop. They have a large bandsaw that cut it with ease. I also had them drill the holes for my angles so that the installation of the bearings were perfect.

Looking good.

Keep up the good work !!

I have been browsing their store myself. I will need 6 pieces all the exact same length when the time comes... Will they cut it for you if you ask them?

[Drools]

80/20 the company does advertize custom work. I received quite a few fliers in my package, I will locate them and see if there is a number you can call.

Looks beefy! good job!

FWIW I cut my aluminum extrusion with a regular blade in my chop saw - it was kinda scary at first but I clamped it down and went nice and slow

Thanks everyone, I still have lots to do.
I'm going to use 1/4 x 3 inch flat bar on the back side of the Z axis to add strenght. I also have some 1/2 x 3 inch flat bar that I might use in places to add strenght. Like on the sides of the gantry.

I did the same - cut it with the carbide blade that came with my miter saw. I clamped both sides to the saw and it worked fine.

Wow, I've never liked the idea of of those type of linear rails but there isn't squat I could complain about your setup. Is that 1" by 1/4" aluminum angle you are useing?

Also, how do you adjust your rollers?

[Drools]

Yep that is 1" by 1/4 aluminum angle, all the aluminum I'm using is at least 1/4 inch.
I mount the 1" angle directly to the 80/20 uprights with 2 x 5/16 bolts, it is actually the uprights that adjust in the 80/20 slots. The 1" angle overhangs the 80/20 by 3/4" on each side, I used my long bar clamps to snugly clamp the angle against the 1" rod, I then tighten up the bolts that hold the upgights in place.
Basically the uprights can slide along the bottom piece of the gantry.
I did not think it was going to weigh this much but it takes 2 people to move it and I don't have the Z axiz or the electronics mounted yet. I never thought a 2x3 made out of 80/20 was going to be such a heavy machine.
The first pic after the CAD pics show the 1" angle sticking out past the 80/20. 2 long bar clamps and an allen key and the gantry is snug against the rails.

Well I'm looking forward to your progress. 80/20 is just yummy. You got me interested in seeing how your going to pull off your Z axis. Also your where and how you will mount your motors and screws. I'll be watching
