Sounds right, I'd buzz the wires with a multimeter to ensure they are all connected properly.Quote
First, it seems to home the X axis wherever it happens to be, so that seems to be an issue. If I either send the command or use the web interface the extruder head will move slightly to the right and be at 'home'. Per David's suggestion, I'll be checking the proximity sensor out when I get back to it. If anyone has any other ideas, the info would be great.
Yep, remove, test and reconnect wires securely.Quote
Second, I've seen is that the bed temperature sensor seems to lose connection. It goes from room temp to 2000 degrees. I touched the sensor wiring a couple of times and it will go in and out, so I'm guessing the connection to the bed is at fault. I'm going to disassemble the bed to investigate.

Lastly and what I think is the most significant issue, when the Z axis moves, the gear that is connected to the threaded rod is very, very wobbly. I've even seen it bind a time or two when I'm running it up and down at a higher feed rate. I've asked a friend to reprint the gears, but it looks like the opening on the bottom is too large for the bearing. Is it possible the previous owner put the wrong size bearing there? I found this modified Z axis gears that I thought I'd give a try. Annoyingly that requires having access to a printer... so I might have to phone a friend on that one.

..I noted that the movements from the Slic3r code to the Cura code are radically different. The Slic3r movements are very regular, making each later almost exactly the same, starting and stopping at the same spot....

Do you think that changing that single setting (after me trying a lot of other things including temp, extrusion multiplier, etc that would indicate that I'm getting too much filament) would do the trick?

I think you should start from scratch with a clean install of your slicer and the default settings, then slice and print a small single wall model e.g. this from thingiverse:
Single Wall Alignment Test
[www.thingiverse.com]
Stop the print or cut the top of the model, 20mm is more than enough to check the print quality
Start by measuring the single wall width, should be same as your extrusion width setting, if not adjust your extrusion multiplier setting
Print slow, keep your eye on where the excessive extrusion happens, either at layer stop or new layer start, then adjust your slicer accordingly and make another test

The faults would be randomized instead of added on top but still be there

What setting would help with the blob at the start of the layer?

I've reduced the amount of filament at the end of the layer by upping the retraction speed to 100mm/s.

Erik,
It gave me very similar results on the walls as when I used the greatly increased retraction speed and a negative extra filament on restart.
However the bottom layer was amazingly better.
I tried a benchy, but it didn't go well. I'll need to do some additional tuning. Thanks!
