We are thrilled to announce a class we are hosting at Workshop 88 (June 12th) and at Fox.Build (June 26th)! Here’s the details:
When – Wednesday, June 12, 2019 from 6:30 PM to 8:00 PM
Where – Workshop 88
What – This class is a collaboration between Workshop 88 and Fox.Build and will be taught by Gail Jo Kelly. She has been 3D printing since 2014. The class will be directed towards people that are new to 3D printing. She will explain how 3D printing works, within the context of the 3D printers at the makerspace. There will be printers on hand for demonstration. Information will cover the process of obtaining a file for print, preparing the file in the compatible format for the printer, using the related software interfaces, along with how to load the filament (materials) and features of the 3D printer. To view 3D printable items, take a look at https://www.thingiverse.com for examples.
This tutorial will show you how to use Computer Aided Design and Computer Aided Manufacturing or CAD CAM tools to create and preview a Gcode file of the Workshop 88 logo that can be run in a 3 axis CNC Mill.
There are 5 main types of machine operations
Engrave (follow path): The tool tip will follow the 3D path provided.
Profile: The tool edge will follow either the inside or outside contour of a path down to the specified depth.
Pocket: The tool will remove all the material within a contour down to the specified depth.
Drill: A drill routine will be executed at each point location. Drill routines come in 2 flavors:
“Peck” used with drill bits, drills to successively deeper depths liftig the bit out of the work regularly to clear chips from the flutes.
“Spiral” used with endmills that are a smaller diameter than the finished hole.
3D relief: The tool tip will remove material above a 3D surface usually specified in a 3D model or a 2D height map image. There are two main modes:
“Waterline” similar to inverted pocket operations where bulk material is efficiently removed outside the 3D model to a number of stepped depths resembling waterline in a topological map. Typically used in a first pass with a large roughing bit to remove the bulk of the material.
“Raster” moves the tip of the bit smoothly over the model in a raster pattern.
Gcode is a “numerically controlled programming language” which is why a Gcode file extension is typically .nc. It is a human and machine readable text file. You will rarely if ever need to look at or edit the Gcode.
This tutorial will demonstrate Engrave, Profile, and Pocket operations, which are the most popular.
There are 4 steps to this tutorial:
Create a .svg file containing paths needed for machine operations
We had a great turnout for the electronics 101 class! It was so great to see everyone who came out to learn a bit about the fundamentals of electronics today. Big thanks to Eric, Paul and Bill who all helped out today with the class. Remember to sign up for the Electronics 102 class next week!
Workshop88 is happy to announce a new meeting schedule staring February 2012. Meetings will be at 7 pm Thursday evenings every week, and the open hack night will be Monday nights. Class schedules and the meetup schedule will be updated to reflect these changes. Board meetings will be scheduled once a month.
We look forward to seeing you at our new weekly meetings.
If you received an email about this post please hit reply and send so we know it worked. Seeing this blog post in your email means we’ve worked out the kinks in our new mailing list plugin. Currently all users are notified when we make a blog post about an event, class, or major announcement. We’ve set up the plugin this way because the survey we sent out to our current mailing list showed overwhelmingly that you all prefer email communication.
If you’d like to unsubscribe just do so in the sidebar of the blog. You may also register and edit the categories you would like to be subscribed to. Hopefully in the future we’ll be making so many posts about classes and events, that we’ll move to a digest model for the mailing list, but for now it’s setup to work post by post.
In other news, we’ve successfully transitioned from our Google Calendar setup to a nice WordPress plugin with Eventbrite integration. Have no fear though, we still have an iCal link available for those of you who use Google Calendar. The events page of the site now shows a list or calendar view of all the upcoming events we’ve posted about. The fancy Eventbrite integration now creates an event and embeds a registration box at the bottom of posts so we can keep track of planned attendance at events and classes, and also allows us to sell tickets.
