Instructions for Pappalardo lab laser cutter
There is a 75W universal laser cutter, avaialble for supervised use in the Pappalardo lab and a 60 universal laser cutter in 35-307 (PDL).
Each time, before using the laser cutter, always make sure that:
Never leave the laser cutter running unattended. Fires are always a possibility. Never touch the optics. If you notice that the optics is dirty please notify the TAs or course instructor. The lens is normally orange/yellow in hue.
If the computer for the laser cutter is logged out, you can obtain the password here (staff access only).
This tutorial covers how to take a .dxf file (from Solidworks or other applications) and import it into Vision Pro clean it up, and cut it. It is assumed that you have a .dxf file and have used the Universal Laser Print Driver before. Pappalardo staff, TAs, or the course instructor can help you with the operations of the laser cutter.
And please please please ask for help if you are ever unsure! The laser is friendly but also potentially dangerous, and should be treated as such.1. Open Vision Pro
The application is located on the desktop. If you're having trouble with this step, you should probably get shop help for the rest of this procedure.
2. Set document to laser cutter bed size
This is not necessary but it will help you lay out your work. 32"x18" should be the default.
3. Import your .dxf
6. Delete the words that student Solidworks includes by default.
7. Make the lines hairline
Choose the hairline icon as shown below (the middle one).8. Make the Line the appropriate color (usually red)
If you are using the Universal Material Settings Database, red (R=255, G=0, B=0) lines are used (by default) to cut through material. Black is for etching, blue is for scoring. The laser cutter will only recognize certain RGB combinations so please use the colors along the bottom bar.
Now your creation should look like this (if you did red and hairline). Imagine your geometry below!
9. Move the drawing to the appropriate location
Because you set up the document the same size as the laser cutter bed, it's easy for you to see where will be cut. Top left of the document corresponds to top left of the bed (if you're looking down from above). Move your drawing to the desired location.
10. Time to print. Yes!
File —> Print
Choose PLS6.75 (which is the laser cutter) and click setup.
Once you have set and applied your settings, click ok and then print on the previous screen. Often Vision pro crashes at this stage (bonus) but your laser setting will be saved.
Open up the Universal Driver (should be a red square on bottom right of start bar, or minimize the rest of your windows) and click the hotdigity go button!
