I’ve read through the discussion, and appreciate sharing each other’s experience. Supporting the material outside of the printer helps remove the material bowing or bending, but the unexpected behaviors mentioned in responses can be sent to support for further review and action.
Unfortunately, resolving this in a general thread is harder, so I would suggest contacting support, especially if it’s been some time since you worked with them I know some points of frustration with responsiveness and not being heard, but the discussed issues are not expected behaviors. Getting any updates to support can help fellow users in the future who want to utilize the feature. When you reach out, feel free to include any previous support ticket numbers related to the Passthrough trouble. The support team can factor that into review and troubleshooting actions.
