ThinkHaus Status: Back Open

News:

Think Haus is back open on Tuesday nights from 6-10.

Equipment:

The CNC mill, the soldering and circuitry table is open. The 3D printer building equipment is available and one 3D printer is functional but needs a little TLC to know how to use and the other needs a drop more TLC. The wood cutting equipment is always open. The lathe needs a bit of fixing on the tailstock but is generally functional.

Projects:

After success with aluminum casting in December with an electric kiln, a proposal for a new kiln to be used at ThinkHaus is brought forward. This kiln would use charcoal briquettes and could melt aluminum in the back area. Cutting out styrofoam parts, the aluminum could do lost-wax-casting. There are several tutorials of how to do make this kiln and the equipment to make it has been purchased. If there is demand it will be made, else the electric kiln will be (privately) used.

There have been few projects going on at this time. If you are working on something, stop by!

Also, Brochure!

Pre-Holiday Break / Post-Holiday Awesome!

Hey all – we’ve reached the “zomg, I need to finish my holiday season projects” stage.

grinch1

We’re going to suspend our regular weekly Open Haus in order to make sure that our members have the time and flexibility they need to make their own awesomeness happen.

We love you all, but we’re busy.

HOWEVER.

Stay tuned for really cool news about 2016-01-01!

First circuit board

I know I made a recent post, but this ties into it. First circuit board cut out on the engraver.

DSCN8589
It is not the prettiest board, but it is okay. It is an audio amplifier TDA7293. I found an amplifier thrown out with 6 of these 180W chips in them. Really powerful little beasts and the power supply worked too. I couldn’t get the old board fired up, so I did the next best thing, remake it.

 

 

 

 

DSCN8583I could show you the EagleCad drawing, the Cad drawings and the G-code, but there isn’t much to show there. I made the code, it works. Here I got the cutter alinged and told the program that this spot is the touch off point for XYZ so that it can start cutting there.

 

 

 

 

 

 

DSCN8584Here it is after engraving. I also cut out little holes, but they are not through holes. I do not have a drill for this collet and the 1/32″ end mill is four flute. Do not use a four flute end mill for drilling and plunging or it will break.

 

 

 

 

 

 

DSCN8587

I drilled out the holes. The smallest drill (shy of the nozzle cleaning drills) are 1/16″ and are rather large for circuit boards, but they worked. The channels are 0.39 mm wide. The engraver end mill is ‘supposed to’ and is advertised to cut a 0.1 mm wide channel.

 

 

 

 

 

 

DSCN8588Here is the bottom of the board. The wide channels actually made the soldering of the board easy, but I would suggest a narrower cutter and a drill for the machine in the future.

 

 

 

 

 

 

And here is the circuit board again DSCN8589from above. I made a mistake thinking that a 460uF cap would be small and was on the original board, and hence the stack of capacitors. Next board is the power supply.

How to use the engraver

Engraver is ready!DSCN8557

(Ready enough for people to use it. There are a few small things I want to do, but it is ready enough!)

So how to use it:

First you need a file and make the G-Code file. I will show Easel from Inventables. It is free and in browser. Just make an account. (http://easel.inventables.com/)

 

Select Sheet

Text

 

 

 

 

 

 

 

Now select the material and dimensions. It will change the settings as needed (it has programmed speeds and feeds already which makes it nice)

Now we can add text or shapes as needed. You can also specify how the tool will cut: outline, perimeter, or fill. Select as needed. If the tool is too big, it will tell you what to do. Outline works all the time.

SVG import

If you use Inkscape, you can import SVG files. This is really Save G-Codeuseful for importing drawings you have made already.

Now, export the G-Code. The export is located in the Machine tab. Click the Advanced tab (shown) then click Generate G-Code and Download G-Code. It will download as a .nc

 

 

 

 

DSCN8565DSCN8564

 

 

 

 

 

 

 

 

 

It is now time to use the machine. You can launch the Fireball program from the laser computer.

To make the machine connect to the Fireball, turn the dial to Engravor from Lazzor.

Turn on the power by pulling the big red button. The big red button will also turn it off if needed.

DSCN8568

DSCN8566

Like the lazzor, find the home position. Press the red X, the orange IO, then press Home All. The machine will home and find the origin points. (This is what I will get to. It isn’t fully ready yet, but you can still use it.)

We need to touch up the G-Code. It needs to be renamed to a *.ngc and add M30 to the end in order for LinuxCNC to find the file.

Next, move the engraver to the origin point. Use Up/Down/Left/Right and Page Up/Page Down to position the tool. Then press Touch Off to zero the tool and next you can start.

DSCN8569

DSCN8570

To turn on the tool, turn on this switch. Super simple. Press the Go button and run the Linux CNC.

What was made is a an aluminum plate. Do not damage it if possible. The plate is made of 1″ spaced 8-32 bolts. The engraver is a .1 mm engraver bit, but it cuts a .4 mm channel. New engravers are optional.

The machine has a maximum travel of 12″ x 18″ and has ~4″ vertical travel, but this can be increased if needed. The machine can cut aluminum if needed. Acrylic will commonly melt if you cut it, so use lots of coolant if you want to cut it.

There are also other CAD/CAM programs that can also make the G-Code, but Easel is free and rather good. Use what you want.

Plasma Cutter Motor Motion

DSCN8554

The plasma cutter three motor controllers are working and spinning some test stepper motors on this board. It is using GRBL on the arduino uno linked to stepper motor controllers as a test setup. We will be moving away from GRBL to a DAQ card to incorporate the torch height controller and other aspects.

Anyone got a 48V 13.5+ amp power supply? Want to boost this from 24V to 48 to give the system higher speed.
