Hi to all!

I'm creating a BOM for the TopsCNC HEAVY model with Nema17 motors.

With a little research on the forum i find that the relation between the working area and the length of the V-slot and T8 lead screw is:

• X axis Working area =  V-slot length - 200mm
• X axis Working area =  T8 lead screw length - 100mm
• Y axis Working area =  V-slot length - 250mm
• Y axis Working area =  T8 lead screw length - 150mm

For my customized TopsCNC i need a working area of 1250mm (X axis) and 850mm (Y axis). So i need:

• X axis V-slot 1450mm
• X axis T8 lead screw 1350mm
• Y axis V-slot 1100mm
• Y axis T8 lead screw 1000mm

Find online i can't find only the X axis T8 lead screw with a 8mm pitch and a length of 1400mm minimum. Do anyone have a link of a shop or website with this T8 length?

Another question is this... a T8 lead screw with 8mm pitch is simply a T8 lead screw with 2mm pitch and 4 principles instead of 1 principles?

Thanks in advance.

Bonjour,

sur X en réel : 

                        Axe X Zone de travail = longueur de la rainure en V - 280 mm

                        Axe X Zone de travail = longueur de la vis T8 - 210 mm

Pour Y en cours de réalisation chez moi, donc difficile de donner des dimensions précises
