Cura Output issues

[JohnCarson 0]

I have an Ender 3 and I am new at this. M problems seem to have stated after I Modified my Ender 3 with the Extruder Direct Drive Modification.

Here is my list:

1. The Cura 4.1 Sliced output has an extension of .gz. (I think I have solved this by trying  one of your experts Solutions), This also happened on the Cura 4.0.

2. When I go to my Ender 3 to print my Object the Extruder heats to 200 degrees F, but the Plate remains cold. When the Printer begins the Extruder 'Z' direction does not move. By the way, just to check my installation of the Direct Drive modification I successfully printed a .gcode file produced before I started any of this. Also, all these problems seem to happen whether I  use Cura 4.0 or Cura 4.1.

 

If this an be solved, I would like to use Cura 4.1 regardless of its issues. I know they will be fixed.

 

This is a wonderful Community of Experts and I DO appreciate the help.
