1 Process
- Cut Angle 0.125" x 1.5" x 1.5"
To 14 pieces of 360mm length
To 10 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, 20mm 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, 20 from the inner joining edge of angle, 40mm 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

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 (7)
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
- Run gctrl code as a processing sketch. For any function of gctrl, press and hold down the key for the popup windows to populate.
