Alright, so my dad and I are making a homebrew delta printer and we managed to get to the last hurdle.

The filament sometimes doesn’t stick to the base (sometimes it doesn’t, sometimes it does) and I think it’s mainly because of the head “oozing” out some filament before it even starts to print, ending up with moving the base, so if anyone knows some kind of custom start g-code that would let us clean it off before it started, that’d be awesome.

Then there’s the elephant in the room. Even before the printing is done the product has obvious imperfections. What I mean is places that are supposed to be solud being hollow and full of bubbly or worm-like holes. We think it’s because of not enough filament being fed in so if there’s someone who knows exact ways of determining filament excrusion numbers in the Marilyn code, that’d be awesome too.

Thanks for any help in advance, and if you need any pictures or information feel free to ask.

Note: looks like the extruder motor slows down considerably after finishing the base layer. Does anyone know if there’s something in the software that would fix that?

Putting a skirt or brim around your print will help with the first oozing issue.

While its really exciting to start doing your first prints, start very small.

Start by printing small calibration cubes, 10mmx 10mm or 20mmx20. Do these at 100% infill. You will start seeing what issues you are having right away. If the cube is concave on top, you are not printing with enough infill or are printing too hot or need a fan for cooling. If the cube is convex on top, you are overextruding. ETC.

Also, post pictures with questions, we can tell a lot about a print issue with pictures.

yep. There are seperate speed settings for first layer and the rest of the print.
