The next step was the wiring, and man a Prusa design has a lot of wires ! ElectronicGeek, you should really beef-up the documentation regarding how and where to run the cables.
During assembly I had done one mistake in the orientation of the Z motors. The cables have to go out the back:
Now an other piece of advise for the EG folks. I would suggest that you install crimped terminals on the side of the wires that go to the power supply. Makes for a much more solid connection to the screw terminals:
I only had ring type terminal available but what you want is what they call "spad" terminals:
Now regarding the teminals on the power supply, the label showing the terminal position was a bit shifted on mine which made me do a wrong connection at first:
That went without much problem, I was able to move X, Y and Z just fine.
My next test was to check the auto-level sequence. I'm used to this having added a similar induction sensor to my PrintrBot Simple Maker. It's as easy as homing X, Y and Z, and then sending the G29 GCode command.
That is where I hit an issue... After homing X and Y, the head and induction sensor that is supposed to sense the metal of the bed was way out of the bed:
If I tried homing Z at that point it would NEVER sense metal and would crash when hitting the bottom of the Z threaded rods... You don't want that.
After some investigation I found that my Melzi board was running a Repetier firmware which it's not supposed to be as this printer is supposed to come with the open-source Marlin firmware. Not expecting much before Monday I fired an e-mail to ElectronicGeek support and to my surprise Eric responded a few hours after asking for picture of the display.
Following sending Eric the picture of the display et responded that indeed I had a Melzi board with a Repetier firmware and it was not supposed to be, should never have shipped that way. Unfortunately the only way to reprogram the board was using a USBISP adapter which amongst all the Arduino stuff I have I did not have that... Eric suggested that they ship me a replacement board which was fine with me. They shipped it Monday and I got it today Tuesday.
During my lunch break I installed the new board and bingo auto-level probing was working. I proceeded with very basic manual bed level and Z-Offset calibration. I was eager to do a first print !
I was really surprised by my first print result, happily surprised:
This is the 50mm calibration angle found here: http://www.thingiverse.com/thing:53668
That is it for now. My next article will be about doing some Repetier configuration and providing some example config.
