What I've Made (Showcase Thread)

[Ted Markson]

We need a showcase thread!  Hopefully I'll remember to snap pictures as I make things with the lobo - we really dig the little machine at Nova Labs in Reston, VA!  

To kick off the thread I have attached pictures of a project we call Hammerhead - a single motor, variable pitch, quad-rotor. The black plates are 62.5mil FR4 cut with a 125mil 5-flute bit on our Lobocnc. Single pass profiles at 20IPM. Plunge was 5IPM.  Cuts like a dream and the geometry is very precise!

OK, that's seriously cool.

BTW, where'd you get the 5 flute bit?

Here is the first finished thing I made for the mill. I am debating what to call her: Amelia, Millie, or Maximilia.

The shark will go. Well, not go, but go into another project. Project 2: Build a Cyclone Vacuum System. It will be built using my 3d printer and a laser cutter. Milling inside was a bad idea. A vacuum will make it less of a bad idea, I think. Project 3 is Build a Coolant Mister. This project is much simpler and deals with a mist maker, two fans, a small power supply, tubing, and my 3d printer.

Jeff, Just saw your edit. The bit I use for most composite work is a 5 flute 125mil cut and shank dia, 1.5" OL, TiAlN finish. It leaves a great finish and I can go 40IPM sometimes more on the Lobo with a 125mil DOC. Link is below

An update on Hammerhead. We tried ArduPilot without (easy) success. We're moving to the KK2 board in the hopes of just getting it to hover.At this point it's an issue of control system - getting a system that will do stabilization for V tail while not limiting the servo travel.

I was given some models to mill for a two part mould to pull composite parts. Renders of the parts are attached with one of just the tool paths. Cambam did a decent job on the 3D rastering with plenty of settings for adjustment (happy when I found arc fit tolerance setting!). This was my first raster part on the lobo and gcode output looks solid.  

I think I put this in the forum a while back but I'll bring it to this thread. It's a simple RGB driver - cutting PCBs was one of our goals for the Lobo. It does this with ease (with the right bits!)  It was drilled afterwards.

Here's an LED ring just for the lobo!  There's a few parts: 

 1) single sided copper clad circuit board for the 30 white LEDs

 2) a 2mil thick insulator made from gift wrap, cellophane material (laser cut)

 3) 093mil acrylic laser cut mount. The two side tabs were bent with a hot air rework station - a heat gun works too

 4) 5VDC wall wart power supply with two 47ohm 1/4W resistors in parallel between + wire and LED anodes to keep the magic smoke inside. 

I'll switch to a constant current supply eventually (FET feedback circuit)

Can't wait for the next job where I can see my workpiece! We do have a table lamp but you know .. it's not the same as the LED lighting effect

I may have to make one of these for myself.

A sign I am making for my aunt who has a house in the woods. I am going to paint it brown with yellow inlay. The G3 went the wrong way on the O, and I will patch that up with plastic wood or something.

[Ted Markson]

That's hilarious, Looks great Nicholas! 

[Jeff]

Does that say "Beware of the Lobo" ?

[Nicholas Andreae]

Here is the updated version. I could also give the .DXF files if people want

[Nicholas Andreae]

It is my best and worst (my only) paint job.

Here is what I cut with the CNC. The GoPro casing designed to be adjustable on the Y and Z axis to balance the weight on the brushless gimbal.

Looks great Dan, tight fitting.  Did you use a burr type mill or another one? 

[Daniel Allen]

Thanks! It is the end-mill type.
