Difficulties when beginning print

Recommended Posts

https://drive.google.com/file/d/1Fd9PavVjrM-74ZaT8SyxTn7LdqWG3vOIhg/view?usp=sharing

I have recently bought a second hand Ultimaker Original. The printer is having trouble when starting printing. I have an idea that i helps, if i help the feeder in the beginning of the print.

I haven't assembled the printer myself, som I'm not sure if there is any adjustment possibilities for the feeder. I can se, there is a screw that apparently adjust the pressure on the PLA in the feeder.

I have linked to an image, where you can se how the beginning of my prints look.

Does anyone have suggestions what i can do to improve that?

This could be several problems,

is the nozzle diameter set correct, or the feedrate.

the feeder screw can be changed, but too tight will deform the filemant, and could need more force to push through the bowden tube,

too lose and it will loose grip.

check the hobbelt bolt if it is clean, try to make a pic what the filament looks like after it is pushed through the feedr (teeth marks)

and if you are not sure if your Cura settings are correct, you can do a reset of all settings.

    • "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.
