LinuxCNC already has that feature, it is called POSITION_FILE and should be added to the ini file in the [TRAJ] section, something like this
POSITION_FILE = last_position.txt

You can look at the .pin files in the firmware directory
to choose a appropriate pinout

7i92t_5abob_encd.bin for example has 5 stepgens and 6 encoders

Note that if you connect directly to encoders and motor drives:


1. The 7I92T I/O pins are like a bare parallel port pins and will be instantly damaged if connected to a voltage outside the -0.5 to +7V range. This is easy to do if system grounding is not 100% correct.

2. If you use bare 7I92T outputs to connect to step motor drives, they should be used in a a sinking configuration, as that is the only way to get full 5V drive:

DRIVE 7I92T
PUL+ +5V
PUL- 7I92 STEP PIN
DIR+ +5V
DIR- 7I92 DIR PIN

Thanks for your help. But position-log.txt doesn't show up to record.

I'm using LinuxCNC 2.8.4 Debian Buster.
