haha it's ok i was only joking anyway.... if i need something answering i'll go straight to someone in a message, i just like to see the discussions round here as it helps me to understand why people recommend the things they do...

2 ballscrews on the X axis is me really covering my arse, if someone says its not needed then thats brill for me.. i just considered the extra screw as this thing is starting to look quite heavy.

the total width of the the whole machine is around 800mm which is double the cutting area i'm happy for this to be as it is, i know i have likely over engineered some parts but i'd rather spend a little bit extra to be sure.. also it might help should i want to machine alu further down the line.

if anyone can shed some light and let me know if i need 2 screws or not and also say if i need to strengthen anything else then that would be great. any information needed just say and i'll sort it out.
