Well, after another extensive period of procrastination I am finally back to work on the RepRap. I have been at it for a couple of nights and have managed to finish all the wiring so I am back to fighting with the software.
I installed the reprap host on my new/old desktop but I can't seem to get it to run. It is probably due to version conflicts with Java but, after messing with it for a while, I decided to switch over to using Pronterface and Sfact as my toolchain. They both installed easily and run fine under windows.
I initially had some problems loading the firmware from the Windows machine until I realized that I had to load a set of drivers for the Techzone USB/Serial board. I guess they were already available on the Linux OS that I was using on my tablet because I am sure that I didn't have to manually install them there. (I am sticking to WinXP on the desktop, not because I like it but because I don't have Linux drivers for the wireless card I have on it). Once the desktop was able to talk to the Arduino I had no problem installing the firmware on the main board and the extruder.
That was where I left off last night. I was not able to get the steppers running but I think that was due to my ignorance of Pronterface. I will go through some documentation today and give it another try when I know what I am doing.
I expect that there may still be some adjustments to the firmware but I will have to get things running in order to know for sure.
Perhaps I will finally extrude.
