1 Process

• Cut Angle 0.125" x 1.5" x 1.5"

To 14 pieces of 360mm length

To 9 pieces of 160mm length

To 1 piece of 60mm length

• Cut Square Tube 0.125" x 1.5" x 1.5"

To 1 piece of 200mm length

• Drill Angle Template

60mm long, 0.125" x 1.5" x 1.5" steel angle.

Use pilot bit. Differentiate the 2 holes as A and B. When looking at the angle's inner perspective, hole A should be up and to the left of hole B.

ANGLE HOLE A - Mark and drill hole A on one angle side, 13mm from the inner joining edge of angle, close to the end of the angle.

ANGLE HOLE B - Mark and drill hole B on the other angle side, 13 from the inner joining edge of angle, 26mm apart (distance is angle-parallel) from hole A.

• Tube Template

0.125" x 1.5" x 1.5" 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. Ensure tube template usage consistency.

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

TEMPLATE MOTOR HOLE Mark and drill 8mm tube-parallel from reference hole.

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

TEMPLATE SHAFT HOLE Mark 70mm tube-parallel from reference hole then drill 1 hole at mark using angle template hole A.

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

TEMPLATE ANGLE HOLE Drill 1 hole using angle template hole B while hole A is set to the template shaft hole with rod.

• X Angles

0.125" x 1.5" x 1.5" x 360mm steel angle (4)

Drill reference, frame, and frame angle holes in all.

Drill shaft holes in 2.

Drill stepper holes in 1.

0.125" x 1.5" x 1.5" x 160mm steel angle (6)

Drill reference, shaft, and shaft angle holes in all.

Drill stepper holes in 1.

Drill motor holes in 1.

• Y Angles

0.125" x 1.5" x 1.5" x 360mm steel angle (4)

Drill reference, frame, and frame angle holes in all.

• Z Angles

0.125" x 1.5" x 1.5" x 360mm steel angle (6)

Drill reference and frame holes in all.

Drill frame angle holes in 4.

Drill shaft holes in 2.

Drill stepper holes in 1 as if the upper shaft hole was the reference hole.

Drill new shaft holes in 2 as if the upper shaft hole was the reference hole.

• Sleeve Bearing

Drill the 12 sleeve bearings through the XYZ setup to achieve alignment.

• Leadscrew Nut

Drill the 3 leadscrew nuts through the XYZ setup to achieve alignment.

• Plates

Drill the 3 plates through the XYZ axes setup to achieve alignment.

• 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
