Progress

4/29/2012: Fab@home is now fully operational in all axes. The next step in its developement will now be to undergo print testing, or alternatively, convert the electronics to RAMPS1.4 with Marlin Firmware now that all electrical components have been confirmed opperational.

2010: Pennsylvania State University (PSU) Fab@home is in operational mode and continue to be in diagnostic form. Within next week, we have an idea how to approaching for the future project.

Fab2home current status

Build Notes

The Fab@home were completed builded by previous owner of the machine. I did check every part to make sure that were properly align and secure. [fabahome.org Fab@home] as a guide, the fab@home were mechanically build as instructed.

Electronic Kits

We were fortune enough to have all the working electronic kits and installed as instructed. Microcontroller for Fab@home model 1:Microcontroller Olimex Philip LPC-H2148 (under ARM) Apparently, we are missing the JTAG cord which is important for flashing the microcontroller. I believe we are specifically looking for OpenOCD with firmware v4. However, the board were flash for firmware v3. Firmware module

Software

Currently, I am using Fab@home v.23 made by cornell university for mendel 1 and driver [email protected]. Both are portable loaded into the computer and are seem to be communicate with the Fab@home.

  • Future project:
    • Alernative software or improving coding

Material

Currently we have Acrylic Winsor Blue available for part to print. More to come on order and check out vendors for harware and material

Diagnostic Notes

Currently, Fab@home machine has a working X axis and Z axis. Y axis does not function very well because there is something wrong with the motor not being adjusted. Also, the X axis seem to be driven itself after the program are close, which is not good. With in this week, we can expected to get the Fab@home ready for future project.
