Click the "GCODE" button near the reset button on the screen for a list of gcodes. Also may want to have a look in the manual.
at G28.

WHich HOME do you want.

There is G28 that sends the machine to what is defined in config  OR

There is G30 which sends it to the true home position as defined by the home switches OR

There is G0X0Y0 which sends it to the Point of origin (HOME) of the work corrds.

Yes I got this one -- If I code G0 it rapid feeds to the home position I set on the manual screen







There is G30 which sends it to the true home position as defined by the home switches OR

 Are these home switches hardware that have  been installed on ther machine ? If so
I do not have home switches




There is G0X0Y0 which sends it to the Point of origin (HOME) of the work corrds.


Not sure what this means?? Is this the y=0 and the Z=0 referring to the axis positions
as they are defined on the axis position dro group?

Also please explain the decimal point that is part of the word "G28.1" ?

If you are using Fixture Offsets (G54 G55 ...) try
G53 Z0.
G53 Y0.
G53 X0.

This sends my machine home and to my manual tool change and part changing position.
