I am getting some errors occurring during the start of a print. I have an Electron Prusa i3 with an MKS 1.2 board. I am running the original version of Marlin that came with the board, maybe 1.0
At the start of a print the message on the screen changes to Sleeping... This is during the heating phase.
When I watch the console I see two points where I get an error saying that the line number did not equal line number-1 (sic) One of these is during a G28 Z0 command and one during the G29 auto level. I can see in the code that two lines N# are on the screen with the same number and same command. I took a look at the G-code export for a model and everything looks fine, so I don't know the cause of the duplicated line numbers.
Another interesting thing is that I can get the same error if I open the console and send "M117 Printing.." the text never appears on the display (It did appear when I used Cura) I tried some other text and found that "M117 Working" also does not work. Many things do work, however, hello, Busy, Idle... etc.
I can get decent prints now that I have ironed out the settings, this start G-code is kind of a minor annoyance.
