I'm working on custom Marlin firmware for my 3D printer using a RAMBo board. The 1.6.8 IDE cannot, for the life of me trying, upload directly to the board, I've spent hours trying to get it to. Always complains about a COM3 permission error. So, I need to compile a .hex file and upload it through the printer's 'install custom firmware' interface.
Problem is, the IDE insists on grabbing onto the COM port. I have to shut down the Arduino software for the 3D printing software to be able to access the COM port. It's frustrating to compile, close arduino, install the firmware, then have to re-open the arduino software again (and lose my place in editing the files).
Is there some way to tell the Arduino software to just run but ignore the com ports?
