New Post Processing Script not registering in Cura 3.5.0

Recommended Posts

Hi,

 

I'm running CURA 3.5.0 on a Windows 10 set-up

 

I have my own Post Processing Script which has run successfully under CURA 2.7, but I have recently migrated to 3.5.0

 

Placing the post processing script in either C:\Users\user\AppData\Roaming\cura\3.5\scripts or in D:\Program Files\Ultimaker Cura 3.5\plugins\PostProcessingPlugin\scripts and re loading CURA the new script does not appear in the script list on the "Extensions - Post Processing - Modify Gcode" screen (Add a Script" drop-down menu)

 

The CURA log shows the following error:

2018-10-17 16:00:50,686 - ERROR - [MainThread] UM.Logger.logException [84]: Exception: Exception occurred while loading post processing plugin: module 'PostProcessingPlugin.PostProcessingPlugin.MCT-ZTweak' has no attribute 'MCT-ZTweak'
2018-10-17 16:00:50,687 - ERROR - [MainThread] UM.Logger.logException [88]: Traceback (most recent call last):

2018-10-17 16:00:50,690 - ERROR - [MainThread] UM.Logger.logException [88]:     loaded_class = getattr(loaded_script, script_name)

To check that this is not an issue with my plugin, I made a copy of one of the bundled plugins (which I know works) and simply renamed it (and renamed the plugin class name). This also fails to load, throwing a similar error.

2018-10-17 16:00:50,655 - ERROR - [MainThread] UM.Logger.logException [84]: Exception: Exception occurred while loading post processing plugin: module 'PostProcessingPlugin.PostProcessingPlugin.ChangeAtZ - Copy' has no attribute 'ChangeAtZ - Copy'

It looks (to my inexpert eye) like the post processing plugin loader may have a bug.

 

Am I doing anything incorrectly or is this a bug?

My apologies ahoeben,

 

By removing non aplha numeric and spaces AND ensuring the file name is the same as the class name the script now correctly loads ?

 

I had forgotten that the name I had assigned in the class (which is displayed in the drop down) was different from the class name, so I'd missed it in the drop down list - my bad ?

 

Many thanks for your help.

      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
