Noob Help!!! Please

Recommended Posts

Hi I have a reprap Prusai3 and I have just finished building it and have spent the last 2 days fiddling with the settings to try and get a good print, after many small cubes i have a cube that looks ok still needs improving that I thoughti would print something else which as you can see from the photo didnt come out very well any ideas on what settings that need to be changed.

many thanks in advance

It would be nice with a little more info about the machine and material you are using

But I'm going to go ahead and assume you are printing in PLA, in which case I would try and lower the bed temperature to around 50 and hotend temperature to around 180-185... Maybe some slightly lower print speed to go with the lower temp.

Your retraction settings also seem wierdly slow and short to me, but your printer being an i3, I assume it has a direct drive feeder rather that the bowden setup of UMs and thus, I am not sure of the optimal settings.

For reference I run something like 4.5 mm. at 60 mm./s on my bowden UM1

Your print looks like you have no or very little fan. I would mount another fan or direct the fan flow better at the print and make sure fan is at 100% by about 1mm off the bed (you want fan off for the very bottom layer).

Also reducing nozzle temp might help. Ignore absolute values like "180C is good" as 200C on an Ultimaker is probably 20C different then 200C on an i3.

Thanks for the reply I have looked at the fan idea but I cant find a way to mount a fan to my set up. Yes I know i'm a compleat noob lol 20160906_224635445_iOS.thumb.jpg.d976c9326e137093e73b35f53d1d5c36.jpg

    • "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.
