hello,
i am trying to get the mesh grid compensation running only i don't relay know what is happening.
as shown in the picture my calibration is in a unusual shape and is 5 mm below the bed or something. right now it looks like a bowl or something like it.
right now i am using a Duet 2 WiFi with Firmware Version: 2.01(RTOS) (2018-07-26b2) on a delta printer.
i also uploaded some file's so maybe this helps
