QuoteRevarBat Adding lots vertexes too close together in an arc can cause shudders and slowdowns in printing, which can add blobs and ripples to the parts as well. Can you elaborate on that?by livingfractal - Developers
So, we are learning about modes of failure in my intro to materials science course. Obviously, that means I have just enough knowledge to make an ass out of myself. Would there be any benefit to rounding the corners, such as the internal corner between the beams and walls on the x-y motor segment, to reduce stress concentrations?by livingfractal - Developers
Yeah, I recycled the gears, and the motor support. I print slow because the printers I use are at a makerspace on a large public university, and “maintained” by students. The number of times they have labeled underextruded and warped ass parts as successful is just obscene. I thought the travel speed was how fast it goes when not extruding (I usually turn on filament retraction). Either way,by livingfractal - Reprappers

This is a journal for my attempt at fabricating a v3.0 Snappy on an Ultimaker 3 using Cura v3.2.1. Feel free to add any commentary, criticisms, and advice.by livingfractal - Reprappers
I'm using the newest version of Cura and an utlimaker. When I open the the described file in OPENscad the prescribed variable is already set to the value that first time I printed the slope calibrator the block fit into. I suppose I should just make a new thread to discuss ideal settings for printing snappy 3.0 with cura & ultimaker. Thank you.by livingfractal - Developers
Well, that phrase "bridge settings" really opened up google to a solution. Thanks. I kind of assumed that using the fans and a low speed would make it work; though I'm never sure what atrocities will occur on the school printers. The student workers, for example, all told me that old cob web looking "triangular" infill was perfectly normal. I suppose I'll try out the bridging test from YouMagine.by livingfractal - Developers
So I noticed in the BOM it states that no supports are required. How are all the large prints with overhangs kept from getting drizzle down? I'm going to be printing this on an ultimaker at my uni.by livingfractal - Developers
