Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am printing a thin box frame the maximum size of my 3d Printer. Let’s get started.<\/p>\n\n\n\n
Workflow wise, things were fairly straight forward, though in reality, things were overlapping, as usual. The workflow started with planning. I want a physical model of how big I am able to print. I toyed along the production line between Blender, Cura (the slicer), and the printer before settling for a squished “cube” that will scale to have 5mm edges and corners. A power outage during the night caused me to lose my model, but I was able to load my hollowed out cube again from a .stl file. Interestingly, it was converted to have triangular faces, so I had to turn it all back into quads before I could continue.<\/p>\n\n\n\n
Meanwhile, my early cube prototypes’ rafts wouldn’t start out correctly. The extruder tip would start moving without the plastic sticking until a few inches down the line. This problem looks like the exact same one as when I printed 36 coins at once for the meetup with Tango a year ago. That time, I could just discard the malformed tokens, but this time, it’s a whole print depending on this line.<\/p>\n\n\n\n
I’ve investigated the matter by learning enough G code to read the instructions the printer was following, and I get the idea it’s following them correctly. Link to a Wiki<\/a>. I learned a bunch, but I literally don’t have anything to show for it this week. No cube, not even one on the printer. I’ve tested a number of theories, including retracted filament to goopy nosel. I’m out of time, but the first thing for next week is checking out the print bed, a factor I dismissed earlier on because of its resemblance to the coin problem earlier. I will say though, that I do have the bed a little lower than I have had it before, so that may be the case.<\/p>\n\n\n\n Another unsolved problem: Whenever the printer boots and I try printing the hollow cube, I’m finding the printer ratcheting when it tries going beyond its print range. I’ve had this happen a couple times, but it stabilizes after a couple false starts without me seemingly doing anything.<\/p>\n\n\n\n Final Question: Two: What’s with my delayed extrusion start? What’s with the printer glitching and self-correcting?<\/p>\n","protected":false},"excerpt":{"rendered":" Good Morning from my Robotics Lab!
