Can't connect my Wanhao Duplicator i3 V2 to AstroBox (RPi 2)

It seems to be related to that moment when the printer restarts. It does this when detecting an active serial connection, reboot, then accept serial input. It reboots just after "Recv: start, and then gets that “0.00000” info.

Heres the log from when I click “test connection”:
2016-03-04 12:34:58,558 - SERIAL - DEBUG - Changing monitoring state from 'Offline' to 'Opening serial port' 2016-03-04 12:34:58,572 - SERIAL - DEBUG - Connecting to: /dev/ttyUSB0 2016-03-04 12:34:58,581 - SERIAL - DEBUG - Connected to: Serial<id=0x1433bf0, open=True>(port='/dev/ttyUSB0', baudrate=115200, bytesize=8, parity='N', stopbits=1, timeout=10.0, xonxoff=False, rtscts=False, dsrdtr=False), starting monitor 2016-03-04 12:34:58,583 - SERIAL - DEBUG - Changing monitoring state from 'Opening serial port' to 'Connecting' 2016-03-04 12:35:08,596 - SERIAL - DEBUG - Send: M105 2016-03-04 12:35:18,608 - SERIAL - DEBUG - Send: M105 2016-03-04 12:35:28,621 - SERIAL - DEBUG - Send: M105 2016-03-04 12:35:38,633 - SERIAL - DEBUG - Send: M105 2016-03-04 12:35:38,639 - SERIAL - DEBUG - Recv: start 2016-03-04 12:35:43,450 - SERIAL - DEBUG - Recv: Info: 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 2016-03-04 12:35:43,454 - SERIAL - DEBUG - Changing monitoring state from 'Connecting' to 'Closed' 2016-03-04 12:35:43,455 - SERIAL - DEBUG - Connection closed, closing down monitor

Ok, I fixed it.
I read through the “Support for Wanhao Duplicator i3” thread, and found the “remove autostart jumper” post.
This immediately solved the problem.

For reference:

  • Remove 7 screws at the bottom, 4 at the back
  • Slide bottom panel slightly backwards
  • Locate the controller board at the top, you should see the “autostart” jumper, remove it.
  • Assemble back together.

I guess a longer timeout after “Start” would probably solve this issue.
