Pretty sure you can do this where you set the home position at homing. (So
it doesn't move). The k&t homes to 38",34"',24 respectively.. it sets
those positions but doesn't then move anywhere else.

I have been happy with it.
Not been using the PI for production - mostly just tinkering.Doing some
pretty complicated configs.
I have had it up for many days at a time with no issues... Running
programs that run hours...

That would be something to try.. Maybe mesaflash doesn't know how to
handle the 192.168.1.1 ip address? Set the pie to something else like
192.168.1.10

I just used mesaflash the other day on the rpi4 for the 7i92. It has been
a while but I think I followed the network directions here...

in the datasheet the
accuracy 0.2 degrees
so, in my mind, it is no better than a 1800 count encoder if that.. I
have used them in the past - they work ok for things like spindle

I have always used DD to create the images. You just have to make sure you
are writing the IMG not the ZIP Something like
sudo dd bs=4M if=~/Downloads/2020-05-01-linuxcnc-pi4.img of=/dev/mmcblk0

have not done any destructive testing - but finally grabbed an oem650 drive
