Wiki Update and CNC Drawing

Update Wiki

You must complete all aspects of each assignment and have them properly documented on the wiki as instructed on each assignment page. Your student page should be clear and easy to read. Use galleries for groups of photos. Size photos correctly for display on pages. Label Assignments. Write descriptions of presented work. Think of it of like a portfolio not a vertical scrolling refrigerator pin-up space. Due By OCTOBER 24th.

In addition please organize your vapax server student folder of your work. Place contents in separate folder per assignment. Create a "working files" folder for each assignment ans "final submission" folder that contains the final files used for your assignment.

CNC DRAWING

Your midterm is composed of a cnc drawing of your own design and execution. Not all aspects of the drawing must be done by cnc, but the tool should be utilized well to execute your vision. Along with the drawing you must present a one page written description of your drawing: describing your intention, your processes (both digital algorithms, cnc plotting, and analog interventions), and your own feedback on the result. The drawing must be a minimum 1656 inches square i.e 4x pieces 23" by 18". It can be a single unified image, a triptych, a tiling of smaller plots, etc... but one cohesive work. (Spaces between separate pages do not count in total 1656" square.) A photo of the result must be displayed on your wiki, along with your one page written description, and lastly, a high-res export of the grasshopper definition(s) used to make your drawing, and any rhino files, posted as gallery images.

Your drawings must be presented on the large wall at the brick patio entrance to Vapa (below Usdan gallery, outside Kinoteca) by 2:00 pm on Monday. LATE SUBMISSIONS WILL NOT BE ACCEPTED'

DRAWING PROCEDURE OUTLINE

FOR 3DT STUDENT USE ONLY!!!!

DO NOT USE CNC MACHINE UNLESS YOU ARE 100% ALERT AND THINKING CLEARLY. FATIGUE/INFLUENCE + ROBOT CONTROL DO NOT MIX. SERIOUSLY.

"General Feedrate Parameters: 30 in/min for "approach", 150 in/min "cutting", 50 in/min "retract"

1) Make sure your design fits with the maximum working area of 22" x 22"
2) Make sure the origin point of your design is 0,0,0. From 0,0,0 your drawing should not be larger than 23" in any direction.
3) Make sure your lines are planar and on the construction plane. (use ProjectToCPlane command)
4) Create toolpath
5) Check toolpath in perspective view to make sure all the moves make sense, nothing dips below Z-0, is higher than z-4" (start and end moves), or runs off the work area.
6) Post your toolpath with the "Torchmate" post processor.
7) Transfer your file to the CNC computer. Keep your files organized - not all over the desktop.
8) Turn on the signal Generator under the computer, wait a few seconds.
9) Launch the Torchmate control software. Start online.
10) Torchmate should be online and you are able to jog the machine. Make sure you the direction you are jogging before moving the machine. Understand you axes.
11) Install your pen.
12) Jog the pen the XY origin of your drawing (must likely the minimum X Y corner of the work area). Double check that the origin of your design and the origin you are setting for the machine are the same.
13) Move your pen slowly to the paper surface. Click down in Z on Slow to depress the pen holder and apply the right amount of pressure.
14) Set the program coordinates to "Zero All". Then Jog the machine up and to a safe starting position.
15) Open your gcode and comment line 4 (see error) by placing that line in parenthesis (). Update toolpath and save.
16) Start your gcode. Just click ok after being asked to insert tool 1 and then press start again. Stand close to the computer to stop the program if anything starts to go wrong. Press any key to stop program.
17) NEVER LEAVE THE MACHINE RUNNING UNATTENDED!!!!
18) WHEN you are finished:
CLOSE TORCHMATE
TURN OFF the signal generator
Cover the machine and computer to protect it from dust.
