Repertier Server killed USB connection for Repetier HOST

I am  having connection problems with my iMac and my Anet A8 3D printer.   I finally got it to run via USB - though unable to upload to SD card - which may  just be an Anet  issue.

A suggestion in another post was to try the server and check if it make a difference.  It does... because Repertier Server  killed USB connection for Repetier HOST! 

Can anybody advise how I get rid of the server and its affects of the  host?

Try to connect and error is -   9:23:34 am: Couldn't open port for device wchusbserialfa120

Advise please...

    You need to disable printer in server to free port for other software.

    I used a terminal code  from a similar thread to this and it removed SERVER files.  I did a cold re-boot - I installed  CH341 - did a cold boot again -  no driver showing in HOST. Installed  CH34x v1.3   did cold boot.... nothing showing in HOST.
    Checked System Report > USB - not listed there.
    Did terminal - no driver listed - check this.

    So  I  have no idea what to try next.... does anybody have this problem??   All was OK until I  installed Server!
  • RepetierRepetier
    Honestly, server does not install or delete any drivers. Noidea why this driver is so troublesome. Until now I even did not need to install a driver at all.

    Could it be that you have parallels and the device is just assigned to the virtual machine? Then you do ot see it in mac.
  • VinnyVGVinnyVG
     I think parallels is an included app on iMac - but I have never used it - I had enough problems Withe Windows XP, Vista and 7 and  moved to Apple OS and  see no reason to  run any windows stuff on my iMac! 
    No matter what I do - when  install CH341 and CH34x v1.3 - the run the  install process and  the  pop up says Successful.... but they do not show in Host and a terminal  check shows they are not installed as does a System Report.

    Am I the only person  on the planet using an Apple OS 10.12..4 Sierra iMac that has this problem.

    I have a mini Mac and on that one -- I cannot use Repetier because what prints OK  from SD card -  does not work using Host -because when it runs - its starts printing about 20mm above the  hotbed!

    I found the solution!

    The problem is that the firmware on  Anet motherboard  - does not use a real USB connection.

    After some information passed from a forum - I  downloaded  - "http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=229&pcid=41 "  Its a USB - Serial bridge.   I rean the  application.... when it finished - restarted the computer, opened HOST and check the  printer settings.  Selected the driver and  then  set up a print controlled from  computer via USB cable... all is well and my world is a better place!!

    Thanks to all  who  tried to find a solution.

    Glad you figured it out. The Prusa i3 does the same thing of using a serial COM through USB. Not sure why, but guess that's a Linux thing.
