@droftarts You're right I didn't select the later firmware in the configurator, noob mistake I'm afraid....

Solved.. There was an M501 at the bottom of config.g which was causing the issue.

Hi, I've just converted my cartesian printer from Marlin/Ramps to Duet. All wiring has been checked for continuity and is okay. There were some initial issues as I upgraded to the latest firmware (3.0) and then used the configurator which generated deprecated commands. After dropping it back to v2.05.1 (I'll upgrade when I've got everything working) end stops and BLTouch appear to be working correctly however when trying to home an axis e.g. X the command G28 X returns the message "Use https://configurator.reprapfirmware.org/ to set up your printer config" followed by error G28 failed. I have used the configurator, I can't find out why G28 is failing. It's probably something very simple but it's driving me nuts, any help would be appreciated.
