@RichRap3D:
For some reason I didn't have the iap4e.bin file in /sys
So the automatic firmware update failed with the message -
17:10:54Error: In-application programming binary "iap4e.bin" not found
17:10:53M997
Can't rename file or directory /sys/DuetWiFiFirmware-1.14.bin to /sys/DuetWiFiFirmware.bin
So I manually copied the new firmware to the /sys and added the missing iap4e.bin
Then booted and ran the command M997 S0
And it all updated perfectly !
The axis wiggle has gone, I'm testing the rest now.
Cheers,
Rich.
Thanks, Rich. I've asked T3P3 to check the contents of the SD card image they use for SD cards sent with the Duet WiFi.
