Running Gcode Program with G54 without any tool offsets

New to Linuxcnc, got my Mesa 7i96 working and able to run Gcode on my DIY CNC without doing any cutting.  The Gode was generated from Fusion 360 with Origin on the TOP Left Corner of the Part.  When i used Mach3, all i do move the tool to the Origin on the part manually and Set G54 offset.  Then program runs.  Will this be the Same in LinuxCNC or it will automatically load some tool offsets from File.  When I tried a to run the program after setting the G54 on TOP-LEFT-CORNER of the part, it moves up in Z and ask me to load a tool.  When press enter it runs the program.

Thanks.

What gui? sounds like you have enabled a manual tool change for premeasured tools.

Origin should be at bottom left, or near left when looking at the machine.
Not a rule, but most are set that way.

With Fusion 360, it does not matter. I always touch off at top left even though the machine origin is front left.
Thats how I did it on a manual mill and its more repeatable against the fixed vice jaw.

Thanks to all. It was my Mistake, There was a G53 Z0 M6 at the top of Gcode File.

after i removed that all was OK.
