Free Tool Libraries for Every Material & Common End Mill Size

Posted by Emily Shore on Jul 14, 2017 11:50:14 AM

Even if you’ve only done just a few projects on the Othermill or Othermill Pro, you know the importance of using the correct feeds and speeds for your design and material type. This is a topic we’ve previously covered in detail in our Speeds and Feeds Guide and Materials Guides, but with the recent addition of SVG milling in Otherplan, we've made it possible to mill designs without creating G-code or thinking about speeds and feeds ahead of time.

SVGs and Milling Metal Cutouts Without Breaking End Mills

Posted by Emily Shore on Jul 13, 2017 11:41:35 AM

Using SVG files is an easy way to mill simple shapes without using traditional CAD and CAM software. When you use SVG files, you can create your design using clipart, screenshots of images, hand drawings, or your graphic design software of choice, such as Illustrator or Inkscape.

3D-Print a Handy Tool Rack for Your Othermill

Posted by Goli Mohammadi on Jun 20, 2017 11:18:31 AM

Community member Troy Gomez recently shared this neat tool rack design he made for his Othermill Pro. He describes it as "very functional with stadium-style seating." The rack, which Troy 3D-printed using black ABS filament, has slots to hold 14 bits and pegs to hold two bit fans and an alignment bracket.

Introducing the Bit Fan, a New Othermill Accessory You Can Make

Posted by Owen Smithyman on Jan 27, 2016 8:42:15 PM

We just developed a really cool new accessory for the Othermill that makes your tools last longer and gives your milled parts a nicer surface finish. It also enables you to to see your workpiece more clearly. Win win! We call our new friend the Bit Fan. And the best part is that you can mill your own Bit Fan in 7 minutes!

Update: based on a suggestion from user Peter Luong, we made an STL version of the Bit Fan. If you don't have HDPE but you do have a 3D printer, you can print the Bit Fan!

Convert STL to STEP

Posted by Owen Smithyman on Jan 20, 2016 11:59:36 AM

This guide shows you the basics of converting an STL file to a STEP file. STL files are a 3D mesh format mostly used by 3D printers, but in the world of engineering CAD and CAM, most software requires solid models. The most universal solid model format is STEP (.stp, .step). Ideally you'd begin with a solid model and avoid STLs entirely, but maybe you found the perfect object on Thingiverse or you used a 3D scanner, and there’s no reasonable way to begin with a solid model. Or maybe you're already doing solid modeling, but you need to incorporate an STL model into it. This guide shows you a file conversion process that has worked well for me.

End Mill Identification Guide

Posted by Owen Smithyman on Dec 4, 2015 11:05:00 AM

It’s easy to get confused when trying to tell the difference between our smallest end mills, so we made a visual guide! Looking at them side-by-side, you can see that there are subtle differences. For example, a 1/100" flat end mill looks very similar to a 1/64" flat end mill, but the tip is shorter and slightly smaller. That being said, even experts confuse them occasionally, so we recommend keeping your end mills organized. Many people keep them in their original packaging, but you can also mill your own bit rack!
