I've been trying to print a part that has supports (Towers) starting on the bed. If I use a raft, the raft prints 1 base layer of about 20% fill, then does hex for 2 layers of about 5%. Layer 4 is when the support towers begin, not on layer 1 of the raft. This causes the first layer of the towers to "Air Print" if they do not perfectly align with a crossing path of the hex. Even if they do maby eades850 - Slic3r
Quoteggherbaz Even though we are getting out of theme here, DC is a better killer than AC. I have put a 9 volts battery in my thong in the past when I was a kid, but I would most definitely don't do that with a car 12 volts battery. A 5 volt supply that can provide 1000 amps of consumption or a 1000 volts with 1/4 amps will kill you "If" and only IF you close the circuit. That's why electricby eades850 - Developers
QuoteMachineHum Quoteeades850 People forget that it is not the voltage that kills, it is the Amperage. Current 40w extruder heater cartridge draw nearly 3.4 A. It only takes 1/4 A to kill. This is true... but only on the most literal level. A voltage source doesn't have a set amperage, is has a max amperage. A 1.5V 10000000000A supply won't do shit to you when you touch the leads... this is bby eades850 - Developers
Quoteggherbaz Oh, Cool. Didn't thought that the voltage was so low. Then forget what I said about the high voltage factor. Very reasonable frequency, it should not create any interference to other electronics. Have you tried to put any proximity sensors next to it? I'm wondering if the electromagnetic field created by the coil will affect them? If you use a shielded input lead with a simple Faby eades850 - Developers
Having been an Electronics Technician and Electrician for over 40 years, I think the idea is brilliant. People forget that it is not the voltage that kills, it is the Amperage. Current 40w extruder heater cartridge draw nearly 3.4 A. It only takes 1/4 A to kill. You can be electrocuted with a 1.5 volt "D" cell battery, yet I have been hit with 250,000 volts from an ignition coil with no ill eby eades850 - Developers
Is it time we as a community begin looking ahead to where the industry is going and begin our own open source development of post/processing and slicing software, as well as the electronics capable of running the resulting code. I personally would love to be able to have more control of my print production than is currently available using STL or OBJ to g-code conversion. AMF makes so many pby eades850 - Developers
Have there been any new developments in regards to the communications with the filament manufacturers/suppliers? All of our discussions are for naught if the filament makers aren't on board.by eades850 - Printing
Quoteeades850 A followon to uGen's comment would be to use a biodegradable/compostable core tube of set diameter and span without sideplates, the coil being shrinkwrapped or tiewrapped to it. This core/filament package could slide onto a split-apart spool prior to unwrapping. This would combine the best of both worlds concerning production costs while minimizing disposable/returnable materials.by eades850 - Printing
OK. As I see we are down to the final nuts and bolts of this. So far we have come up with: Bore: 52mm Hub: 100mm OD, 5mm wall Flange: 200mm OD, 3mm wall Width: 50mm ID Composition High Density compressed cardboard This has sufficient capacity for up to 1kg of ABS, which is the lightest. And would be the 1W configuration. RichRap, you have not posted in awhile. Would you care to weigh in oby eades850 - Printing
QuoteChri If you use cardboard, how do you ensure that the roll is running smooth at the outside ? Alot of people are running the rolls sitting on four bearings (Prusai I2`s , Mendelmax, ... ) ChriI think he is referring to the flange plates and not the core. Cardboard flange plates have a horrible tendency to warp and wrinkle as they age giving the people who use the 4 bearing roll bases fitsby eades850 - Printing
It works for me. My only question is the material. Are you looking at a cardboard/cardstock composition or plastic? Hence, is it reusable, returnable, recyclable or what?by eades850 - Printing
as an aside, when we get core wound wire, it is wrapped with a long strip of clingfilm, such as is used on shipping pallets to contain its contents. This works very well to contain and protect the wire while making it easy to unwrap once spooled by just finding the film end and peeling it off in the same manner and direction as you would unroll the wire, or in this case filament.by eades850 - Printing
One solution would be to contact every filament manufacturer involved and see if we can obtain a 5 meter section of 3mm filament of each type..ie Taulman618, laywood, pla, asa, abs etc. as 3mm will have the largest minium radius when compared to 1.75mm filament. Then either ourselves or by a contracted lab determine the minium radius before unrecoverable diametric/linear deformation. then go wiby eades850 - Printing

I agree with the standard, but as mentioned there may be problems identifying the original source of the actual filament. In the electrical field, materials are marked with an OEM origination labels which identify the maker of the actual part and that of the packager or reseller. This would be an idea to investigate as it would help in identifying the source of materials no matter whose spool iby eades850 - Printing
