CADEX 9 Floor Plans Understanding the planes Laser cutting illustration board Assemble a model

CADEX 9 Use an Imperial System template Create the floor plans based on the images on the next slide Create a flattened (surface development) drawing of all the different roof parts in preparation for the laser cut Dimensions should be shown on your work. No dimension needed to the flattened version of your drawing Complete all the drawings including the flattened version arranged to minimize use of illustration board material Add the prescribed 2/3-tiered dimension format only to the orthographic projections Use zero to all your lineweights for laser cutting For the flattened image, use only Red for cut lines and only black for lines and text you want to engrave Use the proper Sheridan Layer Standard Make sure you draw the plan accurately Use the 11 x 17 Title block prescribed for this exercise Submit a PDF plot/export (save the file as UN_CADEX9.PDF and the DWG file in the dropbox in SLATE Submit an 11 x 17 printout as well using any appropriate scale

Possible Layouts for Laser Cutting It is best to place the etch cut at a horizontal. This will allow the laser cutter to go through the line with one pass rather than going through the line slowly up or down the equipment Make sure you do not have multiple lines on top of each other as a line is equals a laser pass

USE DRAWING FOR LASER MODEL Flatten the whole structure onto a single plane (as if all the roof went down flat on the ground) to prepare your drawings for laser cutting Bring your drawings to our laser cutting session as instructed by your professor Bring an illustration board (not the foam boards) big enough to fit your flattened structure (You may purchase illustration boards from the Sheridan Book Store or from stores that carry office/art supplies for this project). There are about 170 1st year 1st term students, make sure you buy this ahead of time. If you purchase the bigger boards, you may share it with your classmates. Use your drawing created on AutoCAD to upload onto the computer associated with the laser cutter View the video on the V:Distrib/1Laser for instructions on how to use the laser cutter

Colour Override Lineweight Override Select all lines you have defined to be laser cut. Override their colour to red. Only use the red as indicated above as it has a specific RGB value recognized by the cutter. Use the black colour indicated for the engrave pass Select all lines you have defined to be laser cut. Override their lineweight to 0.0mm.

6. 0 Turn on the Trotec 400 series Laser Cutter 6.0 Turn on the Trotec 400 series Laser Cutter. You will need the machine’s key and staff supervision. Ask a faculty member in the lab for the key. Ensure the ventilator is also on. Place your material at 0,0 (top left corner). 7.0 Plot your drawing. In Autocad, press Cntrl+P to initiate a Plot. Set up your plot like this: In Inches 2nd step 1st step 3rd step

8. 0 In Plot set-up, define the print area with a Window Selection 8.0 In Plot set-up, define the print area with a Window Selection. Click at the bottom left of your layout, then the top right to define area. This area must fit on your material (that which you are cutting) at the scale you assign. For example, the layout below will easily fit on 11x17 @ ¼”:1’ Cluster your drawings in a compact manner to save space and material; ensure you have enough material to fit all your drawings. Bristol board (11”x17”) is recommended and will fit ¼”:1’ scale Define a window around your cad shapes in Plot set-up

9.0 The Custom Properties in Autocad’s Plotter Configuration will lead you to the Trotec Laser Cutter’s Properties. Set up the Trotect properties like this: Autocad Plotter Config. Click on Custom Properties Trotec Laser Cutter Print set-up. Note Height and Width. Define this as the area of your material. The drawing layout in the previous slide easily fits on 11x17 @ ¼”: 1’ imperial scale. Press the “JC” button when complete, then OK in Cad Plotter Config. 11”x17” Trotec Laser Cutter General set-up

10.0 The Changes to a Printer Config. dialogue box will appear. Hit OK. 11.0 Plot Job Progress and Job ID appear. Give the Job Name a meaningful name, one you will recognize in the Laser Cutter queue. Use your Last name and print iteration. Press the Apply button. For example, ‘Rafique-1’, or ‘Rafique-2’ for a second attempt. 12.0 The Laser Cutter Job Control (JC) software initiates itself. Its icon will flash. Click on it to open its screen.

13. 0 In the Trotec Job Control, click on Options 13.0 In the Trotec Job Control, click on Options. Ensure your Units are metric (mm). Click the Options button Use inches

14. 0 Click on Material Database 14.0 Click on Material Database. The Laser Cutter assigns colours to actions. For example, RED = Cut, BLACK = Engrave. Since we performed a colour override earlier, RED lines in our drawing will be cut. Ensure RED is set to CUT. All other colours should be set to Skip. 15.0 Set the Thickness of your material. For Bristol board, 1mm is a good option. Click the Materials Database button 16.0 Set both material settings to Paper. If you are trying a thicker cardstock, you will find an option for cardboard, and you may experiment with the material thickness setting 17.0 Set both the Speed and Power to 100. You may experiment with these settings if you choose a different material

You will see your print job in the queue. Double click on it You will see your print job in the queue. Double click on it. Your job appears as a black area. This is the area we defined in step 9.0. Print appears in queue

18. 0 In the Trotec Job Control, click on the Eye button 18.0 In the Trotec Job Control, click on the Eye button. Your drawing will appear. The white area is the ‘printable area’ or the cutting area. We set this in step 9.0. Click the WISYWIG button. ‘What You See Is What You Get.’ Your drawing will appear.

19.0 When you are done, click on the ‘Ready’ ‘plug’ icon at the bottom right. The Laser Cutter is ready to cut. 20.0 The ‘plug’ icon will turn into a ‘Play’ icon. Press it, the cutter starts cutting. The white area is the cutting area defined in step 9.0. A 11”x 17” sheet of Bristol board will easily accommodate your shapes at ¼” : 1’ Keep in mind the cutting area of the 400 Laser cutter is 39” x 24”. 21.0 Assemble your model.
