I have just finished building a C-beam machine and am starting to test it, but have some problems with the GrblPanel software. Following the video, I have changed the settings to the values given in the GrblPanelSettings.jpg file, but if I close GrblPanel and re-open it, the values reset themselves to the original values. I have tried this loads of times, but cannot get the values to stick. I am using an Arduino Nano to interpret the G-code. The machine appears to run OK otherwise apart...
