looks fine to me, but I would perhaps suggest making butt plates, and bolting, to allow for adjustment. I was so grateful for them when I was assembling mine

Add some vertical diagonals too. Diagonals make things rigid.
If you don't have 100x150 steel tubes already bought then I would advise smaller profile with more thickness. Also you have strange overlapping 100x150 vertical posts in lower part of the frame...
thanks guys, i will be using butt plates and as for the strange overlapping its because there was beams going across the bottom too but trying to keep cost down while keeping a strong frame, i have changed the frame now using 90x90 profiles 5mm thick. here is the frame.

That frame revision looks sweet now Ash.

thanks lee
just throwing in my gantry design, the z axis is inside the x axis frame which is supported by 2 200x100mm 10mm thick mild steel box, the z axis has a maximum height of 250mm (would like to go higher but 250mm seems to be the recommended height for rigid and stability.)
what do you think?

Are you going to use screws at that length ? driven with a motor on the end.
do you mean ball screws? if so then yes both sides :) using nema 34 motors and servo drivers.
