Ok. Z AXIS design time. What is the acceptable leverage ratio of a sturdy Z?
My length of linear rail is 450mm. I was hoping for 300mm
Of cutting depth but it seems like there would be excessive difficulty keeping my Z cutting straight with a 150mm (1/3 ratio) binding area for the spindle on a 450mm run. What do you all suggest?
Also, would be wiser to mount the linesr bearings on the spindle plate or on the gantry plate?
Rails on the spindle plate. To make a variable lever. Bearing blocks spaced at 50% of z travel and as wide as possible.
I'll let the resident experts correct me if I am wrong. I'm still drawing up my design. However, this is my understanding.
Few more updates. a redesign of the Z axis and some major work to keep it all straight. moves very smoothly now. Z axis is 6mm steel. working on the ball screws next.
Here's a quick vid of the movement: https://youtu.be/DRLe3EPQ01M
Here's some photos.
