strings and spots on the print

Posted · strings and spots on the print

I printed two models that have been placed one after another at the same time, here is the result:

marvin 2

marvin 1

marvin 3

Some strings and spots came out between them, It seemed like the nozzle was oozing while moving between prints, any advice on how to improve that ?

here is my settings:

marvinPrintSettings 1

marvinPrintSettings 2

marvinPrintSettings 3

The build plate temperature is 60, nozzle temperature is 210 ,

Any advice would be greatly appreciated.

Sorry for my poor english :-/

    Hello

    I believe that this problem can not be avoided to a hundred percent, but:

    You could be the "Travel speed" increase slightly, eg to 175mm / s

    Also you could "retraction lengt" and "retraction speed", slightly increase. The latter also goes directly to the machine under the "TUNE".

    Check also the Bowden whether this is properly seated firmly in the couplings and does not bounce during the printing process.

    Make a mark ring with a fine permanent marker on the Bowden tube, immediately after the coupling neck.

    Is keeping the coupling Bowden not reasonable, then it is necessary to Bowden to cut a few millimeters, so that the claws the coupling can engage in fresh material again.
