Re: Super hard nozzles - Test pilots

Sorry didn't test just the race nozzle change. I did 12 tests. It was a pain changing blocks and feeder systems so I didn't do as many as I wish. I had printing speeds from 7mm^3/sec to 31mm^3/sec depending. Here's probably the 4 most interesting: bondtech feeder, 220C .4mm nozzle: olsson block and ...

Re: Super hard nozzles - Test pilots

The shininess of the block v3 is just for looks. It does not extend internally so it is no harder or slippier inside. Although it can make nozzle cleanup easier I have noticed. Not that I care about that. I'm not going to claim that matchless is any better than olsson blocks but they might be. Some ...

Re: Zero Gravity Direct Drive Extruder

I think this will work with a foehnsturm dual head style solution also as long as the non printing head is parked in a corner adjacent to the corner with the feeder steppers and not in the opposite corner and not in the same corner.

Re: Super hard nozzles - Test pilots

Just to clarify - I think Carl's patent has nothing to do with ruby or sapphire nozzles and instead is related to a newer secret nozzle. But I could be wrong. And it's *that* nozzle, the secret nozzle, that "can't be made in china". Which I translate to meaning, "is unlikely to show u...

Re: Super hard nozzles - Test pilots

Carl asked me to remove the ruby and saphire nozzles from my store. Done. I don't know if this is permanent or just long enough to let Anders version hit the stores. Secondly - I sold 4 so far. 4. That's about 1 per week. I mean I don't know if there is much of a market out there. Maybe there is but...

Re: The Flex3Drive

Here are a few test "cubes". On the top row 2nd from left is .4mm nozzle. Also here are .8 1mm 1.5mm and 2mm nozzles I believe. The center most square you can see about 20% underextrusion on the upper right corner/half. But the layer below is pretty good. The bottom most square has pretty ...

Re: The Flex3Drive

But you can have 50% underextrusion and the cylinders look great still. So it definitely can't detect 10% underextrusion. Plus you can test many different temperatures in less time than it takes to test one temperature with cylinder. If you have a UM2 with the original black feeder than the cylinder...

Re: The Flex3Drive

I'll get you tonight for um2 or um2+. But really it's trivial. 30mm cube. Sliced as above. The point is you look at the gaps between traces with magnifying glass. Layer height matters of course - I mean you have to multiply layer height times speed times nozzle width to determine the volume that you...

Re: The Flex3Drive

Here's an old example. I have dozens of these cubes. This one was for the old black feeder that skips. But for the new feeder it's trickier - you have to look very carefully at gaps between the lines as it doesn't do sudden major skips but instead does underextrusion (filament slipping 10% or so in ...

Re: The Flex3Drive

Well my favorite test is very simple. Start with a 30mm cube. Slice in (old) cura with no walls, 100% diagonal infill, and speed=100mm/sec to make math easier. When you print it, don't start testing until about 3rd or 4th layer when it is at full speed. Now pick a temperature and then start messing ...

Re: The Flex3Drive

That's normal overextrusion and expected on this print. This print was designed specifically for the older UM2 with the original black feeders that would skip a lot and where it is visible when it skips as a perforated ring when you are printing too fast for the feeder. The UMO and UM2+ and UM3 don'...

Re: Ultimaker 3 reveal trip

Evidently they streamed the event to Netherlands but only for the Ultimaker employees. Not for international consumption.
