Elekscam can't find serial port



  • I have just assembled an A3 Laser system from Banggood with the Mana SE controller connected to a Windows 10 PC. I followed the download and installation instructions on this forum, including the reset of the ROM and the driver installation. The COM port shows as COM7 with the CH340 driver but selecting COM7 and then a refresh still produces the "failed to find serial port" message.
    I can connect to the Nano and see that it is running grbl 0.9i. I have checked the "Run as administrator" in the compatibility section of the Properties window. Suggestions?? updates??

  • The problem is purely that EleksCAM only says that it can't find the serial port when the program starts. If I select the comport from the drop-down list I can send Gcode movements and turn the laser on and off, so it is all working. Most likely related to the nano clone using the CH340 chips.
