Tramming Instructions
Tramming the Z-Plus
Tramming your spindle means ensuring the cutter head (Z-Axis) is perfectly perpendicular to the level work surface in
both left-to-right tilt (tilt about the Y-Axis) and front-to-back tilt (tilt about the X-Axis).
Another way to look at it is: you are ensuring the spindle
MOUNT
is completely parallel to the level work surface.
Before you Begin
Level and square the baseframe. Tension all the V-wheels. Tighten all the belts. Optionally, you may also want to
resurface your waste board.
Move the Z-Plus to the
center of the machine and lower the spindle mount to approximately 6” above the surface.
Optionally, if you are working on top of a wasteboard or other potentially uneven surface, you may want to lay a large,
rigid, and perfectly level piece of material over the top of it for best results.
For tramming you will need:
•
Aluminum foil (for shimming)
•
A perfectly square 6” x 6” x ¾” piece of wood (or other leveling aid such as precision 1
-2-3 Gauge blocks)
Adjusting for Front-to-back Tilt
There are two methods for adjusting front-to-back tilt
–
the aluminum foil shim method or the X-rail rotation method.
Here we will focus only on the foil shim method.
To adjust tilt front-to-back, use aluminum foil as a shim between the tramming plate and the Z-carriage.
1.
Place your square block on edge, in the direction of the Y-Axis, underneath the spindle mount.
2.
Lower the Z-Axis carriage with your hands until the spindle mount contacts your block.
3.
Check the spindle mount for level (level about the X-Axis) against the block. If adjustments are needed:
a.
Loosen the four tramming plate mounting screws.
b.
Shim the top half for forward tilt or the bottom half for back tilt.
i.
Place one piece of aluminum foil between the tramming plate and Z-carriage and tighten the
mounting screws. Add pieces of foil as necessary.
Adjusting for Left-to-Right Tilt
Once you have accounted for front/back tilt, the tramming plate allows you to easily adjust left-to-right tilt.
1.
Place your square block on edge, in the direction of the X-Axis, underneath the spindle mount.
