No retraction when travel between support towers

Recommended Posts

Hello friends,

I am having much trouble when printing petg and I have now understood what the cause of this problem is.

When studying the printer during printing I can clearly see that the Cura software does not do any material retraction before travelling from printing one support tower from another. This causes material buildup wrongly. Attachn the right you can see that material is built up in the upwards and left direction. Is there anyone that know a setting for this or can help out to get around this?

Best regards,

What printer as I do not have that problem printing PETG. And since there is not a PETG profile, what is your initial starting profile to control the material?


I use nylon in Cura and when choosing a material at loading time, I also use nylon. I am on a UM3E and S5 though and that may make a huge difference

I use a Creality CR-10S printer. 

I have a profile for petg in my version of cura. The most important setting so far for me was to lower the printing-speed to 30mm/s instead of 60mm/s, that made a huge difference.

I can see that the printer makes retractions at other positions during the printing so the retraction functionality is ok. In this case it seems like bad luck that it is travelling between two support-towers.

    • "Back To The Future" using Generative Design & Investment Casting
      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.
