Problems with "little hills" during initialisation

Recommended Posts

Hello,

I'm using an Ultimake 3 with Cura 4.0 Beta.

During the initialisation of an extruder(colour) the head ist mooving to one corner of the print bed and produces a "little hill" of plastic. Unfortunatelly the print head goes down or about 1 mm. So the platic can glue to the head and will be taken to the printing area - this causes a destruction of the first track of the object and very often I have to stopp printing.

 

I have 2 other printers -- there are different initialisation procedures. They are using their own slicer software.

 

I think these "little hills" are controled by CURA.

 

Is there a possibility to stopp the cration of these "little hills" ? It would be a good solution if the print head would not go down for 1mm rather goes up for 1 or 2 mm. Can I control this with CURA ?

Klaus

Hi

you cannot control how this "hill" is printed, but you can turn it off completely. Look for a setting called "Prime Blob" (which is the "hill") and turn it off.

 

Usually, a prime blob works quite well, but you should also put some glue or whatever adhesion helper you use also to this corner that the blob also adheres well to the glass. I have it always enabled and have rare problems with it.

    • "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.
