As I read through all the CNC build threads I see one thing that keeps standing out to me...big ole motors hanging off the ends of the table and adding extra height to the machines. I've only seen one on here that was belt driven and looked very clean, so got me thinking.
Although it seems like the most efficient method, it looked awkward so got me wondering why one wouldn't use something like a 90 stepper or worm drive transmission.
On the surface (in my mind) it seems feasible but I don't have the actual knowledge/experience. I can see the speed reduction may be an issue but if you gain extra torque couldn't you get away with needing a smaller motor... Also I can see backlash maybe an issue also but looking at some specs is hard to visualize what 20 acr/min would translate into in this application.
Anyone willing to discuss it?
