I’ve put a new Grbl Controller 3.6.1 installer for Windows up on the download site. Note – there is and will not be any version of 3.6 installer.
There is an important change in how position information is handled in 3.6.1:
Manual/Jog control defaults to new mode which doesn’t update the position. This was done to ensure that jog motions are as fast as possible. However, if you want to have the original 3.5.1 and earlier behavior, go to Tools | Options | Display and change radio button to “Always Request but without Idle Check”. Sending files still updates position, it is only manual/jog that does not.
Eventually this will be fixed to have fast performance and display updating but this is a compromise for now.
