So after using this thing for just over a week I will flat out say that unless you want to remake the X plate you are not going to be happy with it. At least not in my case, and here is why:
- The original X plate is thin but made firm by having the original aluminum rails that the Z carriage moves upon. You must remove these to add the new Z-axis slider.
- The Z Axis slider is attached via 4 screws, 2 in the middle and 1 at the top and 1 at the bottom. However, MOST if not all users will have to modify their X plate to be able to use the center 2 screws as they will not align with the slider.
- Given the way this slider is mounted, it has significant sway from front to back. I had changed the way the front plate that the spindle mount attaches to have a wider top and bottom connection to its guide rails and it barely made a difference.
- I machine mostly aluminum sheet metal and cast acrylic, acrylic being upwards of .5" thick. I had to dial all my common toolpaths back a bit because the forward and backward motion just couldnt handle all that excess vibration caused by the lack of stability in the way this thing attaches to the X plate.
Honestly, other than that, which is a pretty big “that”, I do like it so far but I am machining a new X/Z plate for the rails to mount to as we speak out of .5" aluminum plate to add rigidity. If it doesnt work then its back to square one…
