In the interest of saving space in my small garage, I want to mount the CNC as you see in the picture. Has anyone ever had any problem doing this?
I've never seen anyone do it, but I think it could be doable. I think you would need a counterbalance system for the X axis and I also think you would need to use linear rails in order to handle the forces from it being tipped on it's side. How the material is held down would also need some thought I think.
Good idea on the rails, I'm trying to actually source some for the 1500mm Workbee. Any suggestions for sources? For the counterbalance, wouldn't the tension in the screw be enough?
I would worry about all of the weight of the Z having to overcome gravity when the X is moving, having a counterweight would have the X axis seeing equal effort regardless of it it's moving up or down.
Would you think a piston (trunk lid assist) implemented like in this link could work, or are you thinking of something different? Improve CNC Machine Performance With a Z-Axis Counterbalance - CNCCookbook: Be A Better CNC'er
I'm not certain that would work. Here is a link to a guy that built a DIY panel saw, I think you would need something like he implemented for the counterbalance/counterweight. A Portable Panel Saw
A constant force spring would be the best solution. The problem with counterbalance systems is now you have twice as much inertia you have to overcome with each move. Constant force springs add very little weight to the system. Source - Another Source Just be careful to match the weight of the router/carriage to the strength of the spring. And don't even consider using the screw to overcome the force. When the power goes out the weight of the router/carriage will spin the screw (and subsequently the steppers) and cook your controller.
Very nice, I had seen something similar on commercial panel saws but wasn't sure how to source something similar for the given weight needed for a specific system.
