Tramming
Once identified, it is easy enough to correct the tramming. Our entire Shapeoko range can be adjusted as
needed. We recommend designing
a basic square pocket surfacing toolpath for a small 2”
×
2” square of stock
and surface it using a ¼ end mill, with a depth of cut of 0.1mm (0.0039
”),
and a 6.35mm (¼
”)
step over.
Adjusting Nod
Nod should always be adjusted first. To adjust nod, we recommend using metal shims. You can use standard
kitchen foil which is usually 0.024mm (
0.00094”
) thick. You may use specialist shims, if desired. These can be
purchased from most machinist stores.
The shim should be the width of the spindle mount and one piece of foil can be folded over multiple times to
build thickness, as needed.
1.
Loosen the four (4) spindle mount bolts.
2.
Place the shim between the Z-Axis carriage and the spindle mount, at either the top edge or the bottom
edge of the spindle mount, depending on which way it needs to be adjusted.
3.
Re-tighten the spindle mount bolts.
4.
Check the tram.
5.
Repeat steps 1
–
4, introducing more shim thickness, if necessary.
Adjusting Yaw
Yaw is a little simpler,
it’s just a ma
tter twisting the spindle mount:
1.
Loosen the four (4) spindle mount bolts half a turn so the mount is loose but still firmly on the machine.
2.
With the palm of your hand or a soft rubber mallet, very gently tap the edge of the main body of the
spindle/router in the correct direction.
3.
Re-tighten the bolts.
4.
Check the tram
5.
Repeat steps 1
–
4 to re-adjust, if necessary.
Tools to Help You Tram
There are a number of gauges out there that can help you tram to a very high level of precision.
If you want to calibrate your spindle head to a high precision, we recommend the Edge Technology Mini Pro
Tram System (with ¼ shank). Other brands are available but we have found this one to be a high-quality,
accurate tool, well suited to the machine size.
For instructions on how to use the tool, please consult the manufacturer manual.
