1 Process

• Angle Template

70mm long, 0.125" x 1" x 1" steel angle.

1 hole in side A, 1 hole in side B; differentiate these holes after drilling. Which is which does not matter. Use pilot drill bit.

Holes A and B are 26mm apart parallel to the angle.

Holes A and B are 13mm from the inner joining edge of sides A and B.

• Tube Template

0.125" x 1" x 1" x 180mm steel tube.

All holes drilled with only pilot bit. Keep angle template usage consistent by keeping its 2 tube contact faces the same for all holes for a given surface. Ensure tube is on flat surface.

Use angle template hole A to drill reference hole near end of tube.

Mark 15.5mm tube-parallel from reference hole then drill 2 holes each 15.5mm tube-perpendicular from mark.

Mark 25mm tube-parallel from reference hole then drill 1 hole at mark using angle template hole A.

Mark 50mm tube-parallel from reference hole then drill 1 hole at mark using angle template hole A.

Mark 170mm tube-parallel from reference hole then drill 1 hole at mark using angle template hole A.

Drill 1 hole using angle template hole B while hole A is set to the 50mm hole with rod.

Drill 1 hole using angle template hole B while hole A is set to the 170mm hole with rod.

• Edit Processing Folder (copy/paste "Arduino1.0/lib/RXTcomm.jar" into Processing/lib)

• Edit GRBL Folder (edit "MakeFile" such that the serial port name "...tty.usb*" is replaced with the correct name corresponding to your computer OS)

• Upload Microcontroller Code

• Run gctrl code as a processing sketch. For any function of gctrl, press and hold down the key for the popup windows to populate.
