I downloaded Repetier V1.0.6. and I've printed 3 objects with it so far. I did also download CURA 15.04 but haven't tried it yet.
For my first print I covered the bed in blue painters tape, loaded a file from Thingiverse Iron Man Statue (With Support) by SumboDesign, published Jun 28, 2015
I used the slicer in Repetier and was super surprised it said it would only take 1 hour and 8 minutes to print!
I held my breath and hit print. Everything started out great, but halfway through the model broke at the knees and fell over.
I did try again, and again and finally on my third time I was semi-successful.FullSizeRender (1).jpg
Here's my question. Is there a way to print slower? And if so, will that make the model smoother and give it better detail?
I tried raising the temperature to 230, slowing the fan to 60% and slowing the feed rate to 90. It seemed to help a tiny bit.
I also printed a batarang and it came out OK. It seems a little brittle, I'm wondering if there's a way to have the lines print closer so the model is smoother and stronger?
