Welding
04/11/2017 at 09:46 • 0 comments

We will continue with metalworking and give our arm a shot at welding
This turned out better than I would have imagined! It's a better welder than I am.
Welder was a standard 110V handheld welder with flux wire.

Plasma Cutting
04/07/2017 at 11:22 • 0 comments

Today we plasma cut the letter E out of sheet metal.

The toolehead is a standard handheld plasma cutter. I used a small solenoid for the trigger mechanism.

The material is 12ga mild steel.

The toolpath was created in inkscape

3D Contour MIlling
04/06/2017 at 23:08 • 0 comments

Today we Milled the letter P from our Open Source letter series we've been doing
Our toolhead today is a full size 2hp router with a 1/4" ballmill.
The stock material was a piece of brazillian cherry.
The toolpath was created with Kiri:Moto. With all these projects, for better or worse, I tried my best to use open source software. I would have made a tutorial on this if I didn’t have such a bad experience using the software. It’s not the worst software ever but made some unusual decisions with some of its toolpaths. I will be looking for some better software, if you have some suggestions please leave a comment.
2.5D Milling

Today we milled the Open Source Initiative's Logo
Our toolhead today is a full size 2hp router with a 3/8″ 2 flute bit.
The stock material is a laminated piece of brazillian cherry between two pieces of pine.

Laser Cutting and Inkscape Tutorial
03/27/2017 at 07:13 • 0 comments

Today we lasercut the letter E into some cardstock
We used Inkscape to create the gcode for this letter.
We also created a tutorial so you can learn to make patters of your own. See it here.
Our toolhead here was just a little diode laser we source online that we put into a CPU heatsink and clamped to our arm.
Glass Etching
03/22/2017 at 20:07 • 0 comments

Today we etched the letter U into glass
Our tool post, once again, was just a hunk of 2X4. Then we used a hose clamp to secure the rotary tool to the tool post.
We used a diamond bit to do the glass etching and some lightly soapy water as coolant.
The toolpath and design was created in Inkscape.
Hot Wire Foam Cutting
03/22/2017 at 05:21 • 0 comments

Today we made the letter ‘S’ in foam.
The general frame was constructed with 2X2 and 2X3 wood pieces and a 6″ 1/2-13 bolt up the spine.
I used stainless steel wire for the element, but nichrome wire would have been a better choice.
Links to the .svg and .stl files can be found on this project’s thingiverse page
Tomorrow we will do some glass etching
Let's Start With Some Speed Tests
03/21/2017 at 01:09 • 0 comments

I was just running some speed tests and tuning in some of the accelerations. It seems I've hit the max step rate of Marlin as increasing feedrates had no effect.
Banana for scale.
So It Begins

I don't have a lot of photos of the original machine building, but here's a few

The larger grey wheel was an early prototype. After some initial testing I realized that I would need to have much larger shafts for this to be as stable as I would like.
Here's the first set of GCODE I ran.
```
G1 X0 Y0
G1 X50
G1 Y50
G1 X0
G1 Y100
G1 X50
```
More to come tomorrow.

Here's the first set of GCODE I ran.
