Bed Adherence - Problem Solving Sequence - How do I print this? (Printing help)

If you don't need brim all the way round, you could add a box with height 0.2mm and width something like 5mm joining the ends of the arms. It might work and would be less to clean up. It's an alternative to mouse ears.

I like your sequencing, Fabnav. Looks like the issue is mostly related to the bed adherence and arm width. I'll try the brimming with this model, and will start there in the future as well before modifying other variables. Seems like the easiest thing.

Thanks so much for sacrificing your time and material for this. Let me know if I can repay the favour sometime.

Cheers!

I printed the model on my MK4 using the satin sheet.

First I tried Prusament PETG with Input Shaper 0.4 nozzle and 0.20mm SPEED profile. The print came out decent, but not great. First two pictures.

Then I tried some generic PLA with Input Shaper 0.4 nozzle and 0.20mm SPEED profile. I stopped the print when I saw issues with the connecting arms. Third picture.

Finally I printed with the PLA again, with the same settings, but added a 2mm brim. It looks pretty good, but a little work is required to remove the brim. Last picture.

Ha! Nice quip. Haven't heard of helper discs... thanks for clarifying. Appreciated +++.

They're in your Shapes gallery - for some reason Prusa calls them helper-discs - possibly to avoid attention from Disney lawyers.

Cheerio,

Thanks Diem, good idea. Mouse ears is a sensible plan too. If you know of any tutorials or instructions for making mouse ears, I'm all ears. ;)

Wow, that's super nice of you Fabnav. ;) I'll be curious to hear your observations.

Here's the link on Printables. I assume you would want to slice it yourself.

Yes, brim would be the easiest fix, or mouse ears would also work in this sort of case.

Cheerio,

If you upload your model I will try it on my MK4.

Thanks for responding. PLA, Prusament, which was sent with the printer.

I'm wondering if the simplest solution might be to engage brimming on any pieces that are narrow and have minimal footing area. From everything I've read, I don't think the heat bed, nozzle heat, speed, fan speed, Z axis, material, or cleaning will have as much impact as the area.

I completed a calibration that was flawless (required no adjustments) since writing my first post (see link below), which suggests that the printer calibration is working as expected.

Thoughts?
