save the last machine coordinate

good morning guys. I'm a beginner in Linux cnc, I hope you'll be patient with me, my question is the following, I used mach3 for a long time and I'm switching to linuxcnc, one thing I missed was the option to save the last coordinate of the machine, so when I turned on the machine and it was always at the reference I had left, is there a way to create a button on the axis to save the last coordinate?If so, could you tell me how in the most explanatory way possible?I'm Brazilian, and I have to translate to understand, so some things get a little confusing.

LinuxCNC does that automatically even on power cut, just add this line to the ini file, [TRAJ] section:
POSITION_FILE = position.txt

I added the line, as you mentioned, but it didn't work, it opened, but when I move, close Linuxcnc and open it again, it lost all references,
and the coordinates return to zero

Open the config folder using file browser, see if there is a file named
Position.txt
If not, create an empty file using text editor like mousepad or xed or nano ( not office stuff), and name it position.txt and test again.

Here is example:
github.com/LinuxCNC/linuxcnc/blob/54bca1...apy/gmoccapy.ini#L92

You can try it. It is sim configuration. You have this configuration file in your instalation.

I managed it, thank you very much, but I have another question, in Mach3 if I close and open it and want to run the program without referencing it would use the previous reference, Linuxcnc has to reference it again, is there a way to make it keep the last reference after closing and opens again, the position it maintained when it opens again, but the reference does not

You can try NO_FORCE_HOMING = 1
