The sled and Z-axis go together quite easily. 30 min. max and that’s with me stopping frequently. I really like the Z-axis design, and the parts fit together tightly. I do have a couple of questions, though @MetalMaslow -
There are 2 holes tapped for each 4 screws that hold the router clamp to the Z-axis. Do you recommend the top or bottom holes?
After mounting the motor, the gear on the motor is higher than the gear on the Z-axis. Will this be a problem?
Lastly, the Z-axis motor mount bracket had 2 t-slot nuts already fastened to the screws in the upper holes of the bracket, but there were also 2 t-slot nuts already permanently mounted in the Z-axis. Did I mess up something by removing the nuts attached to the screws? It was the only way I could think of to mount the bracket.
