I didn't even bother signing up for their forum when I saw what sort of answers people were getting. Grumpy and unhelpful.
It's a hangout for developers, linux geeks and power users. With that type of membership questions are often answered with links to documents. Much work goes into those documents and pointing users toward them is not being "grumpy and unhelpful" but it could come across as a RTFM kind of attitude,.

If the UI buttons refer to things like G54 it's because offsets are defined that way in g-code. G-code is cryptic but it's what we have to work with. Quit confusing yourself with G92, include G92.1 at the top of the g-code and then forget G92 exists. G54 is easy when you get clear on the concept, it's a coordinate system offset some distance from the machine origins. It's active by default so that's something to keep in mind. Also the UI can display machine position or relative (to G54) position depending on the selection under the View tab.

Nobody says this is easy. Hang in there, it gets easier. And then it gets dangerous
