Printxel. KISSlicer 0.33 layers. Overhead 40mm fan. 20mm/s. 2mm retract. 25mm/s retract speed. 10mm wipe. 1h18m estimate. 1h57m actual.
Print time is completely dominated by retraction.

That's a really good example. Running the numbers at 0.15mm layers and 55mm/s.
8m21s for 0s min layer time.
40m23s for 10s min layer time.
1h59m for 30s min layer time.
Print time is completely dominated by cooling. Even with a huge direct

> "Maybe I just need a much bigger fan" - That'll do it
That's my question. Would that allow me to print this model faster? I'm not so sure.
Here's some numbers at 0.15mm layers, 1 perimeter in KISSlicer. btw. KISSlicer will recompute these without having to reslice which is super nice.
20mm/s, 0s min layer time = 30m
20mm/s, 10s min layer time = 1h1m
20mm/s, 20s min layer time = 1h59m

KISSlicer 0.17mm 0.65 threadwidth, 30s min layer time, 2 perimeters, retraction on, 85% supports that broke and were worthless, overhead fan
With the long 30s min layer time I decided to print the rook at the same time. Estimated build time went from 2h40m to 2h45m or something so why not? This configuration was interesting because most of the actual extruding time was in the rook which put the f

ha! The fan is perfectly visible in the reflection and I totally missed it.
I'm still undecided on my fan strategy. Sometimes it seems my fan is too powerful. Sometimes not enough. Sometimes I'll print some with the fan off and don't understand why it worked at all. The only real given is to make sure to not have the fan on during the first layers.

What cooling are you using? I don't see any fans in that pic.

Good thing the extruder is disposable. I can't imagine those crappy brushed motors lasting much longer than a roll of filament.

I added a "I MADE ONE!" to your thingiverse item.
Printxel. PLA. KISSlicer. 0.4mm layers. 0.6mm thread width. 80deg supports. Retraction on. 2 perimeters. 25% fill.
I'm in the process of figuring out a new fan setup so no fan during the print and I had a ridiculous 30 second minimum layer time so it took forever.
The print came out pretty well minus the supports scars. The little one between t

A couple of thoughts..
1. To be more clear I think model height should be spelled out and not model scale.
2. Why require a minimum layer height? If someone pulls off a better looking print at a larger layer height then even better.
3. Judge only quality with speed being the tie breaker. Everyone should list actual build time along with other settings.
4. Have minimum set of settings to list. La

No, but someone can price something however they want. What does a price point decision have to do with anything?

Which is not in, "the last paragraph starting as a mechanical engineer."
You're just back-peddling and trying to distract away from your conflicting stance between today and yesterday. Which is fine. Maybe now that you have been thinking about this more you better understand the motivation to why someone might delay a source release.

It's been on my todo list for awhile. I think the concept might also be useful to lower the instantaneous current demands by taking advantage of thermal inertia to trade the lower current requirements for greater heatup time.

gerards1111. You are free to create your own design and release your own files and set your own pricing as you see fit. Of course it is so much easier to state that everyone else is just doing it wrong.

With their wording I just glazed past that point. $300/kg Yikes. Thanks for transforming the numbers and putting it into perspective.
From looking at the pictures of the cartridge I'm not sure the print head is actually integrated into it. It looks like it is more of a gimmicky filament loading cap to make it look more professional than a loose filament end.

It was setup where you could pull the platform all the way out which was pretty nice for access when removing prints.

Nope. Shipping is at cost. The only reason why it's possible is because of quantity pricing discounts which is what the Kickstarter campaign is all about.. Getting enough orders ahead of time so that I can buy in quantity.

Karl_Williams. I have a link off the Kickstarter to signup for a kit beyond the initial batch.
gerards1111. The margin is about $100/kit. So not much if you consider the total effort involved, but it's worth it to me. The electronics in the prototype are Sanguinolulu. Initial kits will probably ship with it, but the rest will probably be my design.

Yeah. I guess I broke the link. It's not 100% finalized, but I have it in the queue for review so that I can make it go live when I'm ready. I have no idea how long that will take. I guess it depends on how happy they are with it not having a bunch of superfluous rewards. I REALLY don't want to print off a bunch of bottle openers or whatever. I'd rather focus on delivering kits.

Can you name one instance of a standards committee that did not stifle innovation?
Yes. I do believe the current situation is the best situation possible. Independent innovators innovating independently. I'll call it the IIII committee.
btw, I plug a USB cable into my $30 inkjet printer. It's probably ok to plug a USB cable into my 3d printer too.
