Awhile back I bought some of what it sounds like you are describing and it just did not seem slippery enough.

Oh you did try a fan. Yeah. 60mm should be plenty and more.

I don't understand how this tests ooze. The only difficulty in this print is that it is quite long in one axis making bed leveling more important for first layer adhesion. The jump to the circle is no big deal. Is the idea to keep increasing speed until the jump can no longer be made?
btw. That circle is subdivided a bit too much and communications slows down the nozzle dramatically at 115200 wh

This week the competition is judged on quality vs print time. Quality is completely subjective, but I tried to be technical about it.
If the competition was judged solely on quality I think rhysjones would win it with a very clean print. The print was at 0.2mm layers with a build time of 70m.
When I factor in print time I think these are the three standouts.

I'm not exactly sure when the competition is supposed to close considering time zones, but I'll call it soon after I get up in the morning.

I also used Alibre to design my printer.
The software is fine now, but the company Alibre is very sketchy. I own the expert version, but I can only recommend their most basic offering due to features mysteriously vanishing. In my particular situation I lost the finite element analyst feature because of Autodesk revoking their 3rd party license or something. Alibre's answer? Well, I should just

Some raw extra boring vids. I have a third, but its upload failed. Is this what you wanted or further up?
0.17 layers. 2mm retract. 10mm wipe. 1 perimeter. 15 second cool. 1h27m actual. KISSlicer released today.
I think I need to tweak my settings for the latest version. Seems a bit light on plastic output now.

Apparently I'm a bit slow today. Sheesh. The extra 35mm when going from 165mm to 200mm does needs to be added to both sides of the footprint. So yes the overhead is 90mm and a 200mm version would be 490mm.
I've not seen a Mendel anything in real life. Does the bed stay within the frame footprint when printing to the full extents?

You're right. I measured again. I was off by 100! It's 420 maximum not 320 for 165 build distance and 455 for 200 build distance.

On a Printxel with a 165mm printable Y distance the minimum Y footprint requirements are 255mm. The maximum Y footprint is 320mm. Not recommended, but if it was moved up to the common 200mm printable Y distance the maximum Y foot print would be 355mm. My printer sits next to my keyboard on my desk and is allocated nowhere near the maximum footprint requirements and it's very rarely a concern unle

Interesting insight. Now that you say it I think that might be the cause of my fine strings as well.

I think your pricing is spot on. As the number of printers grow so does the number of people willing to pay for their tools. I don't think you need to use a gimmick like a contest to raise awareness. I think you have the best slicing quality at the moment and I think the only thing holding it back from more adoption are its BFB roots which are confusing to people used to a Reprap style slicer set

The only other review I have seen is from an employee.

Blobtastic!
Left. .33 and 50 minutes.
Middle. .33 and 23 minutes. 195C No wipe. 3s min layer.
Tiny. .17 and 37 minutes.
Right. .33 and 16 minutes. 180C No retract or wipe. 3s min layer.
Estimate for Middle and Right was 9m50s. I no longer think retractions are what causes the build time under-estimation. I think it might have to do acceleration. My acceleration settings are still set at defau

It took me awhile to notice, but if you hover (without clicking) over any of the entry boxes it'll show a tooltip. Wipe's tooltip is:

For fun I printed one at half size. 26.5mm. 0.17mm layers so the same numbers of layers in my other print. 0.85mm thread width! haha. I set wipe to zero so the nozzle would not be playing in the tiny tendrils so long so it's a bit more stringy. 10s min layers. 37 minutes actual build time. It looks nicer in real life than in the photo though that is probably due that it is so small I can't even f

I tried it in 0.8.1 with the default settings and it said it successfully sliced. A quick look at a visualization of the gcode and nothing looked crazy.

Initially I chose the half-size Spiral Lightbulb for this week's print. When printed at half-size the print was more of a test of physics rather than a test of a reprap style printer. The pressure from a thread being extruded was enough to compress the tendrils. I modified the print to include a second spiral in the opposite direction to add structural support and I also removed the base.

hmm. I can't edit my other post anymore. Same print as before just a nicer daylight photo.
I also made a little video because I think this is one of those prints that look a lot better in real life than in a photo. Maybe a video can help express how cool it is. Dunno.
