Rostock Max Hollow Calibration Pyramid Challenge!

Yes, I got the full kit with electronics. I am running my own power supplies (12V and 24V for heated bed).

thanks... I think I may need to run my own power supplies as well. I do have a 24V one I could use on the bed.

Yes, ver 1.1 RAMBO. 175 on the digi pot. I started at 255 and backed off.

Well 175 seems to be the magic number. I can't detect any skipping. Will need to print another test.

That's good news xnaron! Sometimes slower IS better!

Where did you get the small squirrel cage fans?

I got them on ebay...these ones http://www.ebay.com/itm/180389680237

To make up for my less than perfect pyramid, I submit this video entry. Please forgive my novice (and perhaps cheesy) video skills! Also I apologize for it being 6 min long.

It's on you tube here.

Actually I thought the video was really well done. I particularly admire your 1st layer adhesion and thickness. Looks flawless.

I'm also impressed with the suckback and restart on the first layer.

I'm no expert but I think perhaps you following layers may be run just a tad bit too hot maybe. A more experienced printer please chime in here.

[barnett]

Hey thanks! My temp is set at 232 in kisslicer for the whole thing. I could certainly try to lower it a bit. Would that address the goop on the insides of the towers and maybe at the top? I should have requested a slowdown at the top... like min 10 seconds per layer.

Also, I forgot to turn on my desk fan until the towers were already about half a cm high. You can see they're extra sloppy at the bottom.

This is the seemecnc black abs with diameter set at 1.77mm and extrusion multiplier set at 0.94. Single wall test nails the wall thickness with the multiplier set at 0.93, but at 0.93, the pyramid looked like it was starving a bit. Retraction was 10mm at 52mm speed.

[Flateric]

My hollolw calibration pyramid was also seemecnc abs black.

I just double checked my sizing and mine is 1.69 - 1.71 at it's largest, so perhaps this may explain your "extra" looking extruded filament. With my multipler set to 1.

But I am no longer able to find out what my retraction and retract speed were as that was some time ago.

[barnett]

Your pyramid is clearly better than mine. My single wall test resulted in thick wall when I had settings closer to yours and my pyramid was pretty stringy.

I might try again next week.

The pyramid retracts a lot and that can cause starving with long retracts, I find anything over about 5 or 6 mm is basically impossible to compensate for even with additional filament on restart because the amount it needs varies.

Is that because of slipping on the big retraction/feeds?

No I'm not slipping, it's because pressure change isn't instantaneous.
If you try compensating with additional filament, you end up with too much filament.

Any new videos??? That was pretty cool.....

[xnaron]

First try on my modded rostock max. Magnetic ballends and j-head. Silver ultimachine PLA. 5/5 for retraction in KISS. Seemecnc extruder. 185C temp. I'm speechless....

[Jimustanguitar]

Anybody tried it with ABS? I think it's quite hard..

My posted first print and pyramid test was in ABS

Flateric, do you mind posting your Slic3r settings? That cube looks amazing!

[barnett]

xnaron that's as good as it gets!

[darthviper107]

That's a really great result, you're using a different hot end right?

It was so very long ago man I have no idea or way of checking anymore. That was literally the very first thing I had ever printed.

I am about to do another though, with my new mods for testing and I will make note of them.

[xnaron]

Yeah I was giddy watching it print

[xnaron]

Yes a J-Head and my own magnetic ball-arms and effector design.
