CobbleBot Vanguard XL is Alive!

I've been impressed with Robo3D.  They've sent me replacement parts, and my "out-of-the-box" experience required only minor tweaks, so I went for the "Kit Option" for my 2nd printer.

My CobbleBot Vanguard, IMHO, is unfinished.  There were no/missing instructions for:

  1. Putting the guide wheels together (you needed to add some spacers or the bearings wouldn't function properly)
  2. Breaking in the Z Ballscrew
  3. Aligning the Z Axis so it doesn't bind
  4. Routing the wires (and with 2 extruders, neatness counts...)
  5. Mounting the extruders (the supplied Teflon tubing wouldn't let me put them in the "obvious spot").
  6. Proper home-switch mounting
  7. Mounting the heated bed (thank you Mac Quillian)
  8. Calibrating the stepper motor drivers

And so far, operation has been challenging:

  1. Adjusting the Z0 height (Robo3D had an adjustment screw; now it has autolevel)
  2. Since only one side is driven in Z, there is considerable droop across the X axis.
  3. CobbleBot seriously underestimated the required power supply.  10A may be fine without a heated bed, but with the heated bed, you need >16A (the bed draws a little over 10A on its own!).  I'm now using an ATX power supply with 24A capacity.

But... it is Alive. Now to dial it in....
