Newbie First Build 3000mm x 1500mm

[Ross77]

I think what Ross77 is saying is: mount the z blocks on the z support and the z rails on the carriage. Your current z configuration has the rails on the support and blocks on the carriage. I'm sure there are pros and cons but I don't know enough to comment.

Yep thats it. (just re-read my comment and it dose seem a bit hash , I only meant it as a suggestion and not insisting thats it has to be done that way:whistling:)

As it is when the spindle/torch is at the top of its travel it will need a long drop down plate to make it lower than the gantry. Which will put a lever arm on the bearings and a torsional load on the beam,


pros; reduces loading on bearings and torsion on gantry, lowers the C of G, no long plate to flex......need I go on.....

Cons: extra weight on the ball screw and motor if mounted on the rail side, which is easily solved, cant really think of any

As its plasma and using linear rails then it shouldn't be a problem, until the day when you decide to convert it to a routerlol
