Getting the current axes coordinates

Nikolay81

Please tell me how you can get the current coordinates of the axes in G54
This is needed to create more convenient postprocessors.

For example, I write:
G90
G1X0.1F1000
M110(move axies and press START)
(Manually move the axis to a saved position.)
G4P0
#21=#451 (getting x coordinates)
#22=#452 (getting y coordinates)
#23=#453 (getting z coordinates)
G4P0
G0 X50 Y50 Z10
G1 X#21 Y#22 Z#23 F1000 (Now, the axes should return to the saved position.)
M110(Right?)
G0X0Y0Z0
#21=0
#22=0
#23=0

I tried the variables # 451- # 453; # 572- # 574; # 804- # 806; # 864- # 866. They do not work.
Please tell me in which variables the information about the current position of the axes is stored.
And in which variables, it is better to save it (# 21- # 23 are used in slib.nc).

Many thanks for your help. Have a good trip.

Many thanks Ytliu.
How can the settings values be used in G-code, for example:
G1 X100 F # 80 (should work similarly to G0)
What variables are not busy (that is, available to the user) except # 21 - # 24?

#0-#49 is a subroutine local variable that you can use at will. If you need to use system parameters ...

Thanks Ytliu.
And the value of the system parameters can be read from the G-code, or not?
For example, I need to read the value of the parameter #80 to use it for F.
Option G1 X10 F # 80 does not work.
If I write the line #2401=#80 at the end of the "eng" file, and then execute the code G1 X10 F#2401 - this does not work either.
Is there a way to find out the value of #80 from G-code?
Perhaps through slib.nc is this possible?

Many thanks to Ytliu. Now everything is clear.
