Stuff to do in the new year..

here are some things I would like to get done in the new year. Hopefully it will get done since I might have the time. ( I am loosing my job as of the end of May, I will keep you posted. )

here is the list pictures will follow.

To build a stand alone printer / box this to have the following things.

1. Electronics that will operate with out a computer attached along with a interface to select files that are loaded on a cf card and status of the machine maybe also status sent out for a 2nd interface so you can know the state of the printer remotly.

2. a heated chamber for the printer so it will help in printing to be kept at around 100 Deg. F.

3. a filter system for the air because printing with ABS is not the best smell my family thinks.

4. a place to hold the filament and also a way to feed the printer and a way to know if the printer is out of filament.



Also my 2nd thing I would like to get done this year

to print 2 sets of parts one to give away and the 2nd to replace my machine. which will become the stand alone machine.

I would also like to give some clases at the AS220 on how to build Reprap printers.


I hope all have a great NEW YEAR!! and I hope to see REPRAP grow a bunch more in 2009

it is running again

I found the problem was the diodes were shorting out with the ground plane on the board. A word of advise check the diodes and also use the step leds to see if the board is working right if it is working right you should not create a lot of heat on the heat sinks. So the leds should both be on in a stand alone state and both orange when stepping.

Update New Electronics

I figured I would post since we have not posted in a while.

Current status: I have been working on changing out our electronics to the new electronics and which means also testing the new Sanguino motherboard.
the only issue is my stepper boards are not fully working I am not getting my steppers to move they are just vibrating back and forth. I have checked the wiring and it is correct I did notice I am not getting the "status LEDs" for the stepper to both show orange. So I am to next look at why this is happening.

What we have been doing over the last year:
in June we met up with a bunch of people who are interested in Reprap at Olin Collage. we showed the printer even though we ran into some trouble with the Pic firmware.

After this we decided to work on the new electronic boards for the machine. I also have been wanting to be able to run the printer with out a computer connected so I started to work on a LCD board with button interface with help from Zach Smith we made a cool board that communicates with I2C bus so we only use 2 pins to communicate with the Sanguino.
