New Post Processing Script not registering in Cura 3.5.0

[MikeTough 0]

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'

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.

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?

Class names can’t have spaces or dashes; only alphanumeric characters and underscores are allowed.

Sadly, removing spaces and non-alphanumeric characters (and replacing with underscores) either in the script file name or the class name does not solve the problem ? Nor does ensuring that the script class name matches the script file name.

 

Any other suggestions ?

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.
