Update: It worked perfectly! Whatever you did took care of it, I could send my print job directly to Octoprint and it picked it up and started printing immediately. Thanks for the super-quick turnaround!

Absolutely! Thanks for the quick response. I'll test it when I get home from work and I'll let you know the outcome.

These are the lines that get generated when I print to OctoPrint that seem to include the error. I can try to post the entire log file but it's pretty big: 2018-03-28 17:22:41,306 - DEBUG - [MainThread] UFPWriter.UFPWriter._createSnapshot [25]: Creating thumbnail image... 2018-03-28 17:22:41,306 - INFO - [Thread-8] SliceInfoPlugin.SliceInfoJob.run [29]: Sending anonymous slice info to [https://stats.ultimaker.com/api/cura]... 2018-03-28 17:22:41,309 - DEBUG - [MainThread] UM.View.GL.ShaderProgram.load [55]: Loading shader file [C:\Program Files\Ultimaker Cura 3.3\resources\shaders\overhang.shader]... 2018-03-28 17:22:41,890 - DEBUG - [Thread-5] USBPrinting.AutoDetectBaudJob.run [37]: Checking COM5 if baud rate 38400 works 2018-03-28 17:22:42,705 - ERROR - [MainThread] UM.Logger.logException [81]: Exception: Unable to write to file CFDMP_Turntable_Top_v2: 'BuildPlateModel' object has no attribute 'activeBuildPlate' 2018-03-28 17:22:42,706 - ERROR - [MainThread] UM.Logger.logException [85]: Traceback (most recent call last): 2018-03-28 17:22:42,707 - ERROR - [MainThread] UM.Logger.logException [85]: File "X:\3.3\build\inst\lib\python3.5\site-packages\UM\Qt\Bindings\OutputDeviceManagerProxy.py", line 122, in _writeToDevice 2018-03-28 17:22:42,708 - ERROR - [MainThread] UM.Logger.logException [85]: File "C:\Users\Chris\AppData\Roaming\cura\3.3\plugins\OctoPrintPlugin\OctoPrintPlugin\OctoPrintOutputDevice.py", line 302, in requestWrite 2018-03-28 17:22:42,709 - ERROR - [MainThread] UM.Logger.logException [85]: active_build_plate = Application.getInstance().getBuildPlateModel().activeBuildPlate 2018-03-28 17:22:42,710 - ERROR - [MainThread] UM.Logger.logException [85]: AttributeError: 'BuildPlateModel' object has no attribute 'activeBuildPlate' 2018-03-28 17:22:42,993 - INFO - [Thread-8] SliceInfoPlugin.SliceInfoJob.run [33]: Sent anonymous slice info. It looks like the Application.getInstance().getbuildPlateModel().activateBuildPlace function is looking for an attribute that doesn't exist. This is with a brand new version of Cura 3.3 with a brand new version of the Octoprint plugin installed through the plugin manager. Let me know if you need more information.

This update is amazing! The bridging settings are really useful and the support blocker is invaluable. Great work Cura team! Has anyone been able to get the Octoprint plugin working? I can install it from the manager, but the 'Print with Octoprint' button doesn't do anything. I believe this problem happened when Cura 3.2 was released as well, and manually copying the Octoprint files from github worked. Unfortunately, that doesn't seem to work with 3.3. I also tried to copy over the working plugin files from 3.2 to 3.3, but when I do this I get a Python error and Cura 3.3 won't start. I can delete the plugin and Cura will start again, but then the plugin doesn't work.
