1) Page up and page down keys on your keyboard should jog your z. To move two axis together so that they reach their programed posotion at the same time, put both moves on the same line. A G0 is a rapid move, G1 is a feed move. G1s should also have an F value to determine the feed rate. Examples below.
G0 X2.0 Y1.0 Z1.0
G1 F10 X0 Y0 Z0
G1 F10 X2.0
G1 F10 Y1.0
G1 F10 Z1.0
G0 X0
G0 Y0
G0 Z0
The G1, G0, and F commands are modal. They will stay in effect until they are told to do different so all the G0s, G1s and Fs above arent necessary, just giveing examples. This code will do the exact same.
G0 X2.0 Y1.0 Z1.0
G1 F10 X0 Y0 Z0
X2.0
Y1.0
Z1.0
G0 X0
Y0
Z0
2) You need to set up the spindle in Config, ports and pins, spindle setup.
