Checking in with my Ender3 pro

Yeah.. I underestimated how much of a PITA it was to try to sand the top/backtop of the head.. not super noticeable until up close but I think smaller layers would have helped. So it goes.

Lol, yeah you're right about that. The painting goes a long ways, too.

I am not sure where I would store 31 rolls of filament!

28. Some companies like Jayo have switched to a lighter cardboard spool, but now they load 1.1kg of filament on them but charge the same as older 1kg plastic spools :) Still, my rack is already 3/4 full, but I just couldn't resist lol.
 
So I just threw on a new extruder, an orbiter v2.0:

I was not expecting just how tiny this thing is. The BMG + thin motor came in at about 220g. This comes in at an amazing 140g. I really look forward to trying it out.

Yes, wires are a mess. I'm working on it lol.
 
So finally got around to doing some input shaping. Here's a good example of what shaving off 80g from the extruder can do. Left is with BMG, right is with Orbiter 2.0:

So we can see from the recommended shaper settings that my max quality acceleration goes up from 2800mm/sec to 5600mm/sec, while cutting the smoothing factor nearly in half. Yes, it does have me gain a tad of vibrations, but even if I went with MZV, I'd still gain max quality acceleration and lower smoothing factor at the same time.

Just goes to show, lower that weight :D
 
Sometimes a project idea gets stuck in your brain and you have to see it through.

Weekend project - Giant's Toe from Skyrim.

PLA ~ 1h40min print time. Rest of the weekend off and on painting, weathering, and capping. There was a very much "draw the rest of the owl" part missing.

Had a friend in need for a smiling flaming barrel companion to their dumpster fire from last year. A Sunday afternoon in Fusion360 and Blender and voila! A barrel fire that fits a flickering tea candle.

Nice.

On another point I'm very interested in the new V3 SE and KE for a friend. The former looks extremely good for $200 or less and should be even the S1/pro. The KE with linear rails sounds awesome.

*Edit* Worth noting that microcenter has a $200 off coupon for the K1 dropping it to $380. Sounds like they've ironed the kinks out by now.

The speed alone with the rails is super duper intriguing. Cutting down print times would be my only motivation for the extra cash. ha!

Yeah I really want to try one out. I'll be a tad bit bummed if it blows out my modded Aquilla. Then again I've been very conservative with my speed. Maybe I'ts been capable of much more this whole time.

Currently waiting on a machined aluminum bed.
 
Some misc stuff I was making/printing recently..

Trying my hand at quick and dirty topo maps ripped from GoogleMaps. Not bad.

Reprint of Mixi for a niece who broke her other one.

Quick and dirty print of a scanned 2500-1000bc proto Choctaw arrowhead that I wanted to try out an 'obsidian' paint job.
Certainly could have dealt with a bit better sanding, but they did well enough for what I wanted to test out.
Black acrylic with some blue or red highlights. Flubbed on the white/tan to much on the back, but so it goes.
Acrylic satin clear coat over it all.

Some days you get a notion and have to follow it through. Who knows where thoughts come from?

I love printing for being able to load up yeggi or something and see if someone made a solution to a problem I'm having. Next up is a phone grip because my thumbs are sore from holding my phone sideways for a game during the past 2 weeks.

I sold all my cards about 25 years ago for $40 and I had about 10 of those.

I feel that in my soul. Pretty much why I'll keep my cards until I die - sheer laziness to look up old card values. ha!
 
Dual Z First Layer Slicing.jpg

Dual Z First Layer.jpg
1719267467282.png


The visible concentric bottom infill pattern was printed on a single driver "dual z" Ender 3 S1. My Ender 3 V2 has a Bigtreetech Manta E3 EZ board with five TMC2209 stepper motor drivers. I use Extruder #2 driver to run the second Z motor so I can have true independent dual z axis control.
Now I can run a Z Tilt Adjust and get my X Axis extremely parallel with the bed and actually start lifting textures off my PEI sheets. That scratch you see is where the nozzle starts. Maybe I should try switching to monotonic bottom infill to see if I can get rid of that mark. This is a Sprite ribbon cable guide found on Printables.com https://www.printables.com/model/310284-ender-3-s1-cable-chain/

There are no more gaps or cracks on the bottom surface of my prints. The z offset has to be set extremely low, no glue stick is allowed, and I have to print hot and slow (260C nozzle / 90C bed / 8mm/s first layer) with PETG black.
Dual Z requires each Z motor to run off its own driver. Most Dual Z is implemented with a single driver splitting its power output to two motors, but the motors cannot synchronize their heights. With a single Z driver, you cannot correct any slant that your X axis has against the Y axis.
 
The BTT SKR E3 Mini V3 should be able to use its second extruder driver to run the other z axis motor. This is definitely a high end feature, but you should utilize that second extruder stepper driver on BTT motherboards. It is a bit involved, I won't lie. You definitely won't have leveling problems afterwards though. I'm not sure if even Bamboo labs or Prusa's higher end printers have implemented Z Tilt adjust yet. You can print PETG hot for the first layer and then wind the temps down to 240C / 78C bed for the rest of the print.

You definitely need independent steppers for the Z motors with larger 300mm to 350mm sized beds, at that size any uneven heights in the z axis will start to cause leveling problems.

Mini V3 only has 1 extruder driver with 4 total.

Ran tilt on a modded Aquila. Honestly it's somewhat overrated.
 
Eh, bit of a janky mod vs just getting a board with 5 on board drivers.

Though could be fun to do.

As for z tilt, what do you mean utilize? It levels the gantry out. Just didn't seem to matter on a bedslinger once I made sure everything was leveled already.
