PLA 1.75mm? Sorry, I’ve only used ABS before. I suspect your temperature might be miscalibrated. Can you check when it fails if you can push the filament through the extruder by hand and if it comes out looking smooth? If it’s hard to push through, then it might be clogged or the temperature is t…

I’m totally taking a guess here. (I also don’t know what your material type is, nor your filament diameter.) I think your temperature is too high AND I think your speed is too high. The blobs that are caught on the side look really round to me, and not the shape of the nozzle, so that’s what sugge…

It’s a basically a Prusa i3. So right now it’s the stereotypical open source printer. You’ll find plenty of support/parts/data on reprap.org and so you’ll do fine in terms of community support. The hyrel3d’s print heads don’t look like they’re compatible with other printers, but I could be wrong. …

Have you considered building your own reprap? You live within driving distance of surplus electronics shops, workshops, and hardware shops which can help source some parts for cheap. I live in south San Jose but have been going to Sunnyvale for that kind of stuff since I was in elementary school. I…

I have a Lyman filament extruder kit and have had similar issues before. I haven’t solved them entirely, but I’ve done a number of prints using recycled ABS (mostly more prusa i2 parts). The things that helped me the most: 1) I switched out my j-head extruder for a cheap geetech from ebay, and dri…

Hi there! I’m not that experienced in making STL files, but here goes. For a cookie cutter, the easiest thing I can think of would be: 1) On paper, draw out the sort of cuts you want to make 2) download Autodesk’s 123D Design 3) Using their sketch feature, draw out that shape on the ground plane …
