Hi guys; had a wierd idea today while my lathe was running (strange how a mind can wander at work; heheh)
My crazy idea is to make the ball screw static; and make the ball nut spin inside 2 support brgs; I can drive the set-up with a timing belt; this will give a nice reduction and increase the step accuracy; I was thinking about it because I want to remove that lump (stepper motor) sticking out on the end of the table (X axis); I have already designed the Y axis stepper inside the main back support of the vertical slide (Z axis); now if the X axis stepper could be installed in the middle of the cross slide block; the machine would have a nice clean look
Any ideas on this you design guys
