We recently brought Pandapi board and interfaced with Raspberry Pi 3B board. We found some problems with the marlin code already flashed in the raspberry pi such as When I tried to home the x axis of printer, the x Axis reaches maximum end and start hitting.
Also I modified few parameters such as PID values, EndstopPullups in Marlin code and saved. After saving the file, Im not able to run the marlin firmware. During compilation it attached image appears and run button wont work. Please help me out.
