This was an issue with a previous version of gsender and was fixed with an update and I just ruined a sign project where I was using G59.1 on my 4x4 Mk1 Altmill. I didnāt take a screenshot of the console but I saw the G54 in the code after running the first line of code that I had requested. I had to test it with a small gcode project because the console window drops after a certain number of lines. I started my sign project with my Z zeroed in the air and as quickly as I could hit pause the sign projectās gcode had already buffered past the starting code in the consoleās history.
This is a reference to the acknowledgement of the issue and resolving it, but the issue is back in 1.6.4.
I would like to see this resolved but I now know if its fixed again every time I upgrade I have to test it to see if itās still fixed.
