Guys, some log to recommend me?
As you see im looking for something useful, i was thinking abt use UPN because are not hard to find in Argentina at normal prices (i pay 18USD for 1 meter of used UPN 160mm yesterday).
Companies that cut aluminium and steel with water/plasma/laser are very expensive, but looks like i will need to pay for that service.
I get the idea of use UPN because its used in some of the vids that i post, but of course they guys have good welding equipment and mill the welded surfaces to fix deformations.
Im a little lost now... EPOXY very expensive, machining very expensive.....

Two months ago i asked for 1m2 of 10mm aluminium plate and cost 625USD i think thats its too much for my build. so searching alternatives.
Found the Drivers that i talked about a few post ago. Leadshine AM882 manual say that support 80V max, looks like its the only stuff that purchased that can use in the machineLast edited by samsagaz; 08-06-2016 at 12:15 AM.

Guys, what about IPN? not good to use it ? i can use the rails in top/bottom or at side. To level it i can use epoxy. I was checking IPN and looks like IPN280 have 10mm center wall thickness. I can bolt the IPN easy to side towers
Btw UPN and IPN are bad because the welding or exist other problem?
lx (7590cm4) of IPN280 are good, but ly (394cm4) dont looks very good
btw the UPN that i use to draw the first image was just lx (925 cm4) and ly(96cm4)

In post #13 you said you have 1605 ball screws you can use those OK.
Start leaning some CAD Can you get Sketchup or Fusion360 and get a drawing made to start?..Clive

UPN or IPN and angles are not recomended from what I gather because while they have good strength they have a tendancy to twist or deform more than closed box section. As in your video of the fixed gantry machine www.youtube.com/watch?v=K9UA9ZRFwWU UPN when used tends to be closed forming box section for strength.
