UM knocks off the prime tower

Recommended Posts

Is there some specific setting in Cura that minimizes the chances that UMS5 will knock off the prime tower? This happens of course with the largest/tallest prints, which are the most expensive ones, and typically ruins the model because it gets all stringed on one side...

You can make the prime tower a bit wider with the setting "Prime Tower Size", with the downside, that you need also a little bit more material.

 

But you could also try if you really need a prime tower. For some objects, very fine dual prints, it can make sense and you will get better results with a prime tower, but for most dual prints, I rarely use a prime tower and get still decent results. And you have the advantage that you don't have the risk that the knocked off prime tower fails your print job.

Thank you. Are there any Cura settings that would make a prime tower redundant? Does it make sense to print the "shield" with Extruder 1 (PLA), and would that to some extent replace the need for a prime tower?

I never tried the shield, so I cannot give you any advice in this direction. But if you print with PLA/PVA you don't need the prime tower in my opinion or any other replacement for it. I don't print soo much with PVA, but never used a prime tower. @kmanstudios mentioned in another thread that he also doesn't use the prime tower anymore. 

 

I guess a dual color PLA print with fine details, like text in another color, could be a reason to use a prime tower to get sharp edges of the text.

 

If you need a prime tower, then put the tower near to your object, not in the corner of the build plate, to keep the distance low between the tower and the object, to avoid stringing and also put a thin layer of glue on the place of the tower.

 

If you try the shield solution and you have a result, please let us know how it works.

    • "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.
