1 Process
- Angle Template
70mm long, 0.125" x 1" x 1" steel angle.
Use pilot bit. Differentiate the 2 holes as A and B after drilling. Which is which does not matter.
Mark and drill hole A on one angle side, 13mm from the inner joining edge of angle, close to the end of the angle.
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" 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.
