Re: Recommended bolt/thread sizes?

For my SO3, I went with flanged inserts that are internally threaded 1/4-20 and I use 18-8 stainless steel socket head cap screws (because they are cheaper than 316SS) with a 3/16" Cushion Grip T-Handle Key , all from McMaster-Carr. I did a bit of overkill on the threaded inserts and had them in a d...

Re: Thoughts on bootstrapping a Shapeoko XL

I am getting close to assembling my XXL and I am seriously considering getting this extruded aluminum T-slot bed. It is low profile, so I could probably substitute two of them for the stock spoilboard. I bought 10 of the INCRA hold downs , and I already ripped out one threaded insert, and I'd like t...

Re: Tips for enclosures to house electronics?

So, I have had this little project bookmarked for when I have some free time (or more realistically when it reaches the top of the priority list of things to do), but in the build is a steel enclosure made by IAASR that actually seemed reasonably priced compared to some of the enclosures I've seen. ...

Re: Gantry Squaring Problems

Mine is the same way, When the right Y-Plate touches the end plate, the left has an approximately 0.040-0.060in gap. I cheat and just hold it in place and turn on the steppers and use it because I don't get a lot of time on the machine and I don't want to tear it down and open up the holes in the wa...

Re: Experiment with pointilism

I am definitely interested in this. I can think of a few projects once I get my XXL up and running.

Re: Engraving with an 0.0120" Bit

How fast can you run this 0.0120" bit on wood? That is about 0.3mm? :) My settings for this bit are: Depth: 0.030 in max Step Down: 0.010 in Feed Rate: 30 ipm Plunge Rate: 20 ipm DeWalt RPM: 24,000 They are probably conservative for wood/bamboo, but it usually only takes 4-5 minutes to make the eng...

Re: Engraving with an 0.0120" Bit

Thanks. I keep getting "...the smallest bit I will ever need..." and then find one just a bit smaller because I just KNOW I can get a cleaner edge with a specific font and a bit less tearout in a graphic if I just went a little bit smaller.

Engraving with an 0.0120" Bit

Juat thought I'd like to show that it is possible to use small end mills with the ShapeOko. I have previously used 0.0150" bits, but I Decided to go a little bit smaller this time and used an 0.0120" bit I picked up from drillman1. The engraving on the back of the board after I oiled it looks almost...

Re: Carbide Create Images

FWIW, it's well-worth re-creating things as vector images --- you'll get better results than the auto-tracing which is used to make CAM from the pixel images possible --- the files will be smaller, the cuts will be smoother and rounder where they ought to be, and corners will be more sharply define...

Re: Carbide Create Images

I use Inkscape and F-Engrave. I define my sheet size in Inkscape and make my black and white image using whatever text and logos I want. I then save that as a .PNG from Inkscape using 600dpi as the resolution. It is a bit high but I don''t mind waiting for the image to be generated. Since F-Engrave ...
