Hello,Just to join this post as I had exactly the same problem.
Since day one I use the SM Original with the enclosure v1.1 and was running firmware Snapmaker-Base-2.9 without having any trouble.
Few days ago, I updated the firmware to Snapmaker-GD32Base-2.11 and from that moment I started to have the same behavior as described in the first post and the only way to solve it was to disconnect the enclosure cable as the macro commands did not work.
Firmware problem?
