3D Printer yet?

[Zucca]

[xrunner]

So I'm sitting here in the living room with a bourbon & coke, a cat on my lap, and watching a baseball game. All is great.

My print in the other room has finished (printing scale models of shipping crates for my model RR). The camera shows it's done (the models are shifted to the right out of view). I want to print more - but I can't because I have to go in there and remove what is on the bed first.

WANT:

Auto-bed scrape-clean so I don't have to get up! 

[Monkeh]

Get a belt printer!

A profound, professional, 3 hour investigation. On the 1th of September.      

Yeah, well... one benefit of it taking 6 months to get to me: By the time I have it in my scaly little paws, we'll have discovered all the ways it can burn your house down and I'll have a BOM all ready...

on its way to me right now:

Fortunately(!?) or unfortunately, this New World of 3D printing, is escalating RAPIDLY!
It's the old adage of "when should I buy it" etc. They've now been around for a few years, to say the least, but have vastly changed
in regards to the Technology/Type/Speed. Should I buy some relatively cheap (years ago) $1000 unit, now going for say $200 ??

I'm reminded of Trash & Treasure Boot-Sales years ago, where some ill-informed seller wants $500 - $1000 for an old IBM PC, when
it is only worth $10 now, (if that!), just because their system cost them then $3000 or some such rubbish back then! 
Not to mention that 'Technology' has changed/improved massively since the 1st advent of such '3D Printers'. Now the push is towards the
Carbon M1/M2 style, where there is NO reels of 'plastic', but a machine 'pulling out' a creation from a viscous liquid bath, with no heating,
being formed from a specialized light projection underneath, (and Oxygen as an extremely thin stripping layer), with incredible resolution!!

Where does it end???  Obviously it doesn't!!! We are a LONG way from the imaginary 'Star Trek' where they order the ships computer to
create a food dish or glass of 'Scotch' in a matter of seconds in a replicator!!  Then again, my Grandfather actually thought that 'Fax' m/s
were a lie, to trick people!!      We gave up trying to explain how it works!!   

Let's face it... what we buy 'today' will be antiquated junk in another 5 to 10 years, so do not think of it as an 'investment'.
However, all of life is like that now, but it is now on an ascentotic curve...

True, but if we always wait for the latest and greatest, we would be waiting forever

I play (sort of) piano and synths.   What was groundbreaking in the digital piano world  20, 10 years ago is considered rubbish now. When someone comes onto a piano forum and says they can get this 10 year old digital piano for zyx, people point out that the low end of digital pianos currently out are far superior.  On the flip side, I have bought new and subsequently sold numerous 80's synths that are now worth a fortune.

Same with mobile/cell phones, PC's, Cameras etc etc etc

Yeah, we have people printing details for cakes which used to require some artistic talent with a icing sock... 

mnem
But a decent, basic cream cheese icing, once the staple of names like Betty Crocker & Duncan Hines, is now a unicorn...

[xrunner]

Well ... the wheel still hasn't been improved. 

[mnementh]

Well, no my point is the opposite; we now have technology that allows a novice pastry chef to print art that used to be the product of years and years of study and practice under the tutelage of masters... but something as simple as a decent cream cheese icing, which you used to be able to buy at any grocery store, is no longer available and must be made by hand. 

The only thing you can buy in the grocer's is a dozen different variants of flavorless chocolate-flavored or evil bland butter creme.

Even real vanilla is a freaking rarity.

Everything is just poured into the flavorless sausage grinder of doom and we're supposed to be pleased with our soylent beige frosted soylent yellow cakes as if there never was any such thing as flavor.

create a food dish or glass of 'Scotch' in a matter of seconds in a replicator!!

In pretty much every episode of "ST:TNG," Picard asks the replicator for "Tea, Earl Gray, Hot" and a cup or mug or some other container of tea materializes. And he drinks his tea.

What happens to the cup or mug or other container? Do they get recycled? Does the swabbie come through his Ready Room after hours and clean up the mess?

My printer has an elephant's foot issue with most of my prints and I'm having a heck of a time getting rid of it.  Adjusting the printing speed helped a bit.

The very first layer prints perfectly, but after that everything seems to get too hot and the layers squish for about 10-15 layers.  The printer readout shows a sudden loss of print head temperature (from ~220 down to ~200), so I think it's trying to compensate.  The problem is that there was no actual temperature loss.  Over those 10-15 layers it gradually corrects itself.  Prints with thin walls are minimally affected, but flatter prints or prints with a lot of material on the first few layers are affected the most.

At first I thought it was feedback from the fan coming on too strong, but it happens even with the print cooling fan off or when it is set to a constant speed.  I suspect there is an obvious calibration or other setting that I have fat fingered at some point.  Any ideas?

What's your bed temp? High bed temp was a big contributor to elephant's foot for me.

My first reaction is that you're running way hot (if you're printing PLA); my prints seem much more dimensionally accurate when I print between 195-205° with bed at ~50°, particularly with PLA+.

On my Diggro (E3 clone), I found I could all but eliminate elephant's foot without losing adhesion by preheating the bed to ~60°, not preheating the head, and printing as above. My Cura settings use a 2-4mm brim with a starting point of ~0.2mm or one line width from the print, and allowing any required supports to build on top of said brim if needed. The squish makes contact with the brim but it is just transparent-thin, and it pretty much falls off the print.

HTH!

I throw mine in the fireplace.    Maybe you can ask the guys at FlashForge; they appear to have a wormhole to the ST universe.   

WARNING: Full-Frontal Nerdity Follows:

The transtator, the transformational discovery which is the foundation of almost all Federation technology, operates on the principle that there is no difference between matter and energy; both are simply different states of the same "thing", and all that is "lost" in the conversion between one state and the other is a small amount of energy, mostly that used for the required computation. 

The show has numerous references to "matter reclamation units" or waste extraction systems or similar terms; usually represented as a chute or lidded chamber one placed unwanted materials into. One must assume this is how the matter of used replications was reintroduced into the energy/matter cycle.

Reading the above article, evidently the whole concept became a bit of a rabbit-hole story-wise, causing much confusion and debate among hardcore anal/OCD trekkie circles. 

TL/DR: Yeah... it's hard to believe this technology uses less energy than a dishwasher, FFS.

Pssst... Replicator.

So I finally got to compile the marlin Zuk version, but the stupid Arduino IDE is throwing stupid errors on stupid me.
After 5 min googling about those errors I will switch to VSCode and Platformio, anyway the Arduino IDE is more "TH3D than Marlin" so I will run away.

TO DO is now learn Platformio IDE, should not be hard.

Moreover I want to turn off the beep/buzzer in menu, it is driving me crazy and SWMBO wanted to throw my Ender out of the window yesterday for that.
I can't believe they have not already implemeted this. I will research and post back, I found a chirp() function which is promising in the last version of Marlin.

Ah, I adjusted the Z screw stop axis and installed the glass bed, any elegant suggestion (no paper clip, thing) on how to keep it in place?

The show must go on.

Oh just wait - it's got a whole lot more to throw at you besides a beeper.

Oh yeah... E3 loves to sing while she works.

I use tape.  Scotch Magic here in the US.  Just ordinary office paper mending tape.  It has no stretch so it keeps things down and not moving.  It is easy to remove when necessary.  And has survived bed temps to 60 C.  Ymmv if you run the bed hotter.

CR-6SE Misery continues:

After 2 weeks of sending multiple eMails to every customer support address and the KickStarter Support portal for the campaign, which is SUPPOSED to be a direct line to their support queue, I finally found the CReality Support Forum actually not "Error 502, Bad Gateway" and submitted a customer service request there.

Result? "Your post is awaiting moderation."

Now will it flash?

everything went well, I now have the last Marlin up.

The message "SD Init Fail" probably because there is no SD card inside.
Yes I have no chirp chirp as Menu feedback:

https://www.dropbox.com/s/c18vd217fot3ew5/2020-09-07%2022.22.07.mp4

when I do auto home I got X220 Y220 Z0 on the status screen display, the 220s sometime are blinking. yes I have to RTFM.

Now the bad news....

 

Murphy got me again, I pulled away the Laptop with too much joy, the connected USB Cable ripped of the micro USB port on the Ender.

 

will fix it, just a PITA! Stupid me.

Treat your 3D printer well and it will return your kindness many times over.

Except when it's CReality on a KickStarter. Then, "caveat emptor" and "No good deed goes unpunished" appears to be the order of business.

That said, my post in the forum DID actually go up... no response from anyone at CReality tho.
