I will address the two separately (precision and accuracy):
This is most closely related to the resolution. The blackTooth uses the same mechanical drive (timing belts and pulley) of the same ratios and specifications, so the two machines will be the same in this respect.
The output of the machine (the final physical work) matching the input given to the machine (the design data or instructions for the machine to product the physical work. This has to do with both resolution and how well the machine will hold up over time and through environmental changes.
With that said, both machines have very similar attributes in mechanics and structure. The overall structure is made of MDO (Medium Density Overlay) and has a very low coefficient of linear expansion with regards to temperature change, so accuracy will not be affected in any appreciable manner over time with the two machines. The Vertical Laser XL does use more industry standard rails to hold the heavy gantry, but this will be differ appreciably since the blackTooth will exhibit rigidity by virtue of its size.
It really is best to consider the application and size as the main aspects of deciding between these two machines.
Hope this helps.
We're looking at getting the vertical so we can run both large and small jobs on the same machine. It sounds like running a small job on the vertical (using a positioning jig) would provide results at least as
good as running the same job on the blacktooth. Does this sound about right?

Is there any precision or accuracy difference between the vertical and blacktooth lasers?
