Cheers mate, still need to brace the bed frame a little more at the bottom and brace the side gantry plates but would like some feedback if anyone thinks i will run into any problems. will be extending the bed by another meter at the bottom for a 4th axis, z height is 200mm but can also do up to 400mm by making the 4th axis centre in line with the bed so with the z axis boxed in do you think this is strong enough for what i wanted it for?
