I thought our drivers were the same?

no, im on a chineese 5 axis TB6560, iv no idea if they will be enough, its a small machine but the gantry weighs almost as much as i do :) .... i think in some parts its over engineerd, i was trying to play it safe, the 20mm plate on the gantry sides are the week link.... i designed it with 200mm x 40mm extrusion but valuframe ran out of stock and couldn't find any

its amazing how much more the gantry sides flex in the Y axis compared with the X axis
ill stick some sort of buttress on them if its a problem

I thought the forum had something to stop double posting...oops. That's the problem with having a really slow internet connection.

I'm not thinking today am I, you mentioned the driver only a couple of posts ago, sorry!

Plate is the worst possible cross section for bending in the Y direction. Maybe you could securely bolt some bigish aluminium angle to the plate to make it a bit stronger...ideally get it welded on.
All that aluminium profile must have cost a lot.

I intend to look at the servo controller on Wednesday, or this weekend at the latest.
