Print Challenge

[David Mason @davidmason83 My Robox is a Blue Commercial Version]

May I put a challenge out their for everyone with ABS (Green if you got it)

I am experimenting with very small and delicate samples and I have found a small 9V Battery Holder/Tester with 2 very small holes that must remain through the print. Top .STL (Testr) at http://www.thingiverse.com/thing:261720/#files

Could anyone try and print this and see how they got on. My image shows that the holes were almost covered up after around layer 10. I am thinking of reducing my flow multiplier down to around .75 to .8 to try and reduce heavy layers, see if that helps

It only takes about 15 mins to print!

Hi, this is my first ABS print. A little tip, purge first and heat up the nozzle before u try to exchange the reel…

Im watching and writing at the same time and will add also images.
So far it started ugly check 1st pic. I didn’t add a brim so im wondering why the brim was added, i also noticed that the ABS behaves bridle…
I used custom fine settings and changed also the feed rate to 0.9, was just curious..

..next try, but wait !

After a second look a second thought came up and i went with it, freed it from the ugly brim and the little blobs with my awesome robox tools and voila. But the zoom of the phone does not forgive and shows my bad cleaning job.. anyway it fits =D

@edthehorse “But the zoom of the phone does not forgive and shows my bad cleaning job”

Definitively nice zoom and sharp picture! It is not cleaning that’s the issue - it is finishing layer. I am sure it can be done better.

“I used custom fine settings and changed also the feed rate to 0.9, was just curious..”

It might be worth trying lowering ‘Filament multiplier’, too. Mine is at .90 or .85 depending on material.

This object is really good (small and delicate) for testing

Nice attempts, did the two holes stay when it has finished?

[BHudson @bhudson]

I have found that increasing through-hole sizes in ABS and PLA by .025 inches tends to give more accurate through-hole results.

[Clicky @clicky]

Would that be around 0.6mm? Twice the width of 0.3mm nozzle?

[Clicky @clicky]

Here’s what I’ve got:

I didn’t get object is so small. I tried to ‘cheat’ - set speed of printing to virtually half of what is in ‘fine’ profile, set material’s filament multiplier to 0.8, feed rate multiplier to 0.8, 0.99 for fill, layer height 0.1mm, 5 solid layers at top and bottom, 4 perimeters (more or less fine profile defautls), all 0.3mm nozzle and yet - not much better in close-up than yours…

Hm. I did expected a bit more visible improvement with all the settings maxed to as fine, as slow and careful as possible…

Here’s hoping that AM 1.01 will sort some of this out

[Clicky @clicky]

I am not sure it is problem with Slic3r. Nor AM… But I’ll be glad to be proven wrong.

I was able to print this with no issues see images. Sorry i am not able to switch back to abs at this point as I would have to re-calibrate everything, but my previous prints with abs are of similar precision but only slightly less clean, however i stay away from abs because of the shrinkage issue that is not consistent between parts that need to fit together. So my settings includes a skirt, it gets the material flowing and help me confirm that I am getting good adhesion, if the skirt sticks well then the print also sticks. Like the raft setting the skirt setting can only be changed by manually editing the profile in the robox folder. I don’t print with the fine setting as i found it to print with blobs, whereas the normal setting with some tweaks and set at 150 micron gives me the best results so far, i also print everything with the .3mm nozzle except the first layer which I print at .8mm. I included some photos and my general settings. Note that the holes are not perfectly round, I think that is due to my belts not being as tight and I need to clean and re-oil the unit.

Thanks for taking the time to do that Aimdy

[Aimdy @mistsoul]

anytime, let us know if you make any progress, I am sure everybody is exited about the upcoming AM release, hope it does wonders to all our prints!
