Don't know if it makes any difference, but my machine is a MakerGear M2. Here are the annoyances I have seen so far:
- E-Stop button doesn't work.
- Disable Motors button doesn't work.
- No Speed/Feed overrides.
- Value input boxes up/down arrows don't repeat with long press.
- No running estimate of time remaining or % done for currently running print.
- No notification of total execution time when print finishes.
- No live line tracking.
- No macro buttons.
- On the Accessory Controls tab, the Heated Bed light never comes on.
