I am just getting started on building the MPCNC. Yesterday I went out and bought 20 feet of 3/4 " EMT Conduit and I’ve started printing all the parts. I am just confused on how I can determine what length of tubing I need to cut. According to the info on this website:
3 Rails X = Usable Width +264mm (10.4in)
3 Rails Y = Usable Depth +264mm (10.4in)
2 Z Rails = Usable Height + 190mm (7.5in)
4 Legs = Usable Height – 13mm (.5in)
1 Lead Screw / Allthread = Usable Height + 76mm (3in)
Table will be 6.5mm (.25in) longer in each axis direction. (30in X rail will need a 30.25in table in the X direction)
I determined that I want my X and Y axes to 30 in x 30 in. I am not sure how to figure out how much Z-axis length I need. I will be using this CNC machine to cut foam board so I assume it wont be a lot?
