  • Do you happen to have a video example? It sounds like there might be a few different issues going on at once.

    Does it seem to hit the printbed in the same area? It could be that the bed itself isn’t fully level. I’ve seen some prusas have the frame itself warped. It might be worth looking into the nylock mod. That combined with the octoprint plugin for prusas leveling should help getting your bed perfectly flat and rule out any issues there.

    You mentioned updating firmware and sd cards but what is the slicer you are using? I doubt that would cause any of the issues you are seeing but worth checking off the box.

    The oozing could be due to the hot end being set too high for your filament or potentially it may be too saturated and needing to be dried. How old is the filament you are printing with/how are you storing it? What material/temps are you running?

    There could be something up with your stepper motors and/or wiring. If you move the bed/extruder around through the settings menu can you replicate any of the odd behavior?

    Another thing to check is if your z axis is fully level? There are some small tools for getting a consistent height on both lead screws. I’m curious if one of the steppers is going bad and leading to things getting misaligned and other knock on effects.

    Thanks for asking for help vs just giving up. When I first got mine I had a hell of a time with clogged ptfe tubes in the hotend/extruder. I had to disassemble my printer like 30 or so times to ultimately figure out it was because I had the headers flipped for the heat sink fan and the part fan leading to bad heat creep and maybe a hundred or so hours of pain.

    Edit: on mobile, I’ll try to swing back tomorrow and drop some links for the various mods/tools






  • I’ve interviewed a fair number of entry level devs. Someone having gone to college for cs may understand some more abstract concepts within programming more and have a better handle on data structures and things like bitwise math and big O notation. They may fair a bit better on some more gotcha interview questions when the rubber meets the road often didn’t offer much more than another junior dev who was self taught or went to a camp. A lot of the concepts are useful but I’ve found the tasks often handed out to these entry level roles don’t benefit from having that depth of knowledge. People going through the camps and self taught have usually had more training on how day to day business may need them to operate and solve problems with ci/cloud orchestration etc. I am usually hiring for people with a strong sense of curiosity more so than someone who can tell me which sorting algorithm is technically more efficient. When it comes to developing I’ve personally followed the make it work, make i good, make it fast process (usually in that order) if we are being honest businesses more often than not care almost exclusively for the make it work portion.

    All of this to say there are absolutely fields the benefit from deeper understanding of math, software engineering practices, etc. I don’t think the bulk of development jobs are that though.

    Calling out my own bias, I am a college drop out that was a cs major with a focus on game design. Ive got jobs working as a sys admin, developer, cloud engineer, reliability engineer etc. These roles will almost always choose for experience over collegiate accomplishments.
