@Marion j :
My prints suffered for a while until i figured out TWO MAJOR things. The spring style coupler flexed way to much, causing some z-banding, under/over ext at times as well. SO i replaced it with a solid coupler. You can either 3d print one or buy one for $8 off amazon. One that was swapped out, alot of issues went away. I then adjusted vrefs to appropriate lvls. Then my prints were as smoooooooth as butta!!!
I use a mix of s3d or prusa slic3r. S3d is working better than prusa slicer at the moment because prusa gives me a crap load of ripples in my prints, where as s3d does not, and i print them exact same settings and printer haha
@Jesse: Bro, i feel ya! it drives me crazy. I have had 13 semesters of math, 5 of physics, 2 programming classes, both of which made me CRY alligator tears and snot out my nose… I HATE HATE programming. it makes no sense to me. anyway. I never had any hands on in school with 3d printers or building, except one small intro to shop class that i took OUTSIDE of my engineering degree. I did not operate the CNC machine but i got to see it work. So i decided to take matters into my own hands. I took a solidworks and drafting course over the summer last year where i became cswp and certifide with inventor as well at a tech school, not my university. Last year was the FIRST time i ever saw a 3d printer and i got to use it. not to sound cheesy, but i was so happy to see one and get to use it, i stared at it for about an hour watching it haha. I purchased mine in may of this year:)
@Ryan: I wish we were local as well haha. Utah is a chill place but hard to find some engineering internships. ATK, the palce that makes rockets here, is always full. My neighbor, now in his 90s, was the one who told them not to launch the challenger rocket. he was the manager of the engineers at the time. I have talked with him in the past to gain some insight. This MPCNC of yours, should help me understand some things and i will for sure put it on my resume.
My printer prints the parts fast. i printed all 4 corner brackets and locks in 6 hours with 55% infill, 0.28 LH, and 0.5EW. So far so good. I should be getting the conduit from one of my students this week
