I can print using Simplify 3D, but not in MatterControl

  • Hello
    I just downloaded MatterControl 2.0 on my Windows 10 desktop. I do not start MatterControl, but started S3D and see it is using com10 and a baud rate of 115200. I close S3D and open MatterControl. I went to the top lright 'vertical dots' and selected Configure printer, went through the steps of correcting my bed size (300x220) and build height to 300. and set the baud rate.
    Then on the top left, I select connect and it acts like it connected, but none of the controls work to home or preheat bed and extruder. I opened the terminal window and it says, "Communication State: AttemptingToConnect

    N1 M110 N1*125

    Communication State: Connected

    I can't print or anything. Windows Device Manager shows Com10 as "USB Serial Port", which it is.
    S3D prints to the machine and controls it through the same port fine.
    I'm confused!!!
    Any ideas?

    You could try to power cycle the printer after closing S3D out, it may be that because of closing the process for S3D that the printer did not necessarily drop the connection so the COM port is still active and MatterControl cannot connect into the system.
