I have tried twice to print the “test” Marvin file, and both time when the printer gets to the key ring loop everything goes bad. The first print the key ring was a gobbled mess,(picture 4) so i tried again, and when the print got towards the top i slowed the print speed to 50% (using pronterface). Any ideas of what to try next? I glued the “ring” portion back on which is the substance you can see in the first 3 pictures. Also you can see a difference in the texture on the backside of the print, maybe the bed is not level?
Temp was 185, i am pretty new to this and there are so many speed settings i am a little overwhelmed. Will i have to change the extruder speed as well? Sorry i dont have more of the settings, i am at work now and didnt think to write them down.
Somewhere on your slicer settings there will be one called minimum layer time, to me it looks like the printer is running to fast over the small area, and thus not giving the layer enough time to cool before the next one is put down on top, this has an accumulative effect and mushes the plastic up…
so by increasing a min layer time, you essential give the layers enough time to cool.
Getting a good quality marvin is good training! as the experience you gain from messing around with settings can be used when you start printing for real!
