Getting 802.11r Fast Transition working with WPA(2)-Enterprise is quite painful. There is information on the forums, but things have changed quite a bit during the last few years. These are notes mostly for my own benefit.

Tricky bits as of OpenWRT 23.05 (in Luci "WLAN roaming" tab of wireless network settings):

NAS Id should be set to something unique, like the name of the AP.
Mobility domain defaults to a sane value. Leave it empty.
Reassociation deadline's default of 1000 is bad. Apparently Cisco uses 20000 here, setting that appears to be helpful.
FT Protocol "Over the air" is the good setting.

If you're using WPA2-PSK, check "Generate PMK locally" and you're done. Save&apply and it should just work.

	* Tension X,Y,Z axis: https://www.youtube.com/watch?v=MV-rbU5Fpfc
	* Check that the extruder screw has the right tension: https://www.youtube.com/watch?v=8bACUeH6WDs
	* Check that all screws are tightened
	* Level the X axis, use two glue sticks on both sides of print bed to determine if the X axis is leveled: https://www.youtube.com/watch?v=Cmwq9r5tePk
	* Use the "paper test" to set the Z offset (run G1 Z0 F300 on the printer to position the hotend to the lowest position on the print bed)
	* Use fine tuning to find the right Z offset
	* Print the modified spool holder for added stability: https://www.thingiverse.com/thing:6631744
	* Print the Z axis gantry support for added stability: https://www.thingiverse.com/thing:6516352
	* Lubricate X,Y,Z axis with lithium grease
	* Print first layer test.
