Z-Axis does not appear to be working on Ender-3 Pro So, the wife got me a Creality Ender-3 Pro 3d Printer for Christmas.

Assembly was easy, axis movements are all solid... when I go to print the test-dog.gcode file provided with the machine, it comes out looking... flat.

Not kind of flat. TOTALLY flat.

The Z-Axis motor works - I can move it with the machine's control panel - and it moves on it's own for repositioning of the head for printing purposes, but it doesn't seem to be moving 'up' for each new layer.  Layer height is set for 0.1&nbsp;mm, nozzle is .4&nbsp;mm. No settings changed in the G-code, or on the machine (and I did a "reset to failsafe" before attempting to print anything).

I'm relatively new to additive manufacturing, can someone help out here?
It turned out that there's something wrong with the G-code file that came with my printer.

I downloaded a calibration cube from Thingiverse and printed it - while it wasn't 100%, it did print viable. Now I need to get into details as to quality, and I suspect that too will be a factor for the G-code used in the printer. I'm looking at "Ultimaker Cura" to figure out the changes in G-code based on option changes.
