cnc for marble

[yasser]

Dear chaz thank u for your reply and of course u r right here are some photos for my first machine and the major problems are
1- the max speed i can use is 400 mm/sec after that i loose steps dramatically and also this consumes a lot of time as the max step down is from 2-4 mm, i use the steppers directly i think i should be using speed reduction method ,i use nema 34 steppers 11n.m
2- the aluminium sections are very weak for this application i think i will be using steel as the new machine will be 3m in th x axis and 2 m in the y axis so i am searching for a stiff beam design for the length 3m
