Prime tower enhancement with PLA and PETG for supports

Bambu Lab Software Feature Requests

Hi,

When using PLA as interface layer support for PETG bodies - and also enabling the prime tower, the prime tower can get messy and the nozzle may be full of PETG.

I think a solution could be to ensure that a solid layer of PETG is present before the first PLA layer is put onto the prime tower. This way the PLA layer will not need to bridge over the previous PETG layer with poor adhesion.

So, in general: Ensure that there exists a solid layer of the previous material on the prime tower before a new type of filament is put onto the prime tower.

Is this forum also monitored by bambu engineers?

Shall I put my request elsewhere?

The chances of your request being seen here by Bambu’s development team is fairly low.

I would instead suggest logging a github issue.

Edit… I see that you already have.

Link for future reference.

PLA & PETG don’t stick together, you should just increase the flushing volume & turn the prime tower off.
