Nice project. Yes, those linear bearings can be expensive, so a lot of projects use v-groove rollers now. The T-Slot version I also published is another approach, albeit more expensive. It is a lot more relaible, though.
I think most CNC type applications assume there are no obstacles in the workspace - avoiding those would clearly change the drawing. There are numerous vector conversion programs - maybe you can go from an intermediate format like gcode?
Looks nice - the base cabinets definitley give you more surface space for the printer etc.

Great info - thanks!
The cabinets fit inside the frames, so I just used a few drywall screws from the sides to connect the cabinets to the frames. Be careful on the placement so the screws don't go into the cabinets.
Thanks. I do not think this approach would be suitable for very high precision positioning. Using stepper motors would help, as well as making sure everything is well tuned. But, there are many XY table hardware options out there that may be more reliable. I have not used them, so cannot make any recommendations. Good luck!
Looks great! All set for tyhat new TV! :-)
Cool - glad to hear it! I am waiting for the fluorescent tubes to fail in my garage :-)
