Re: Enter by February 1st 2015 to win an Ultimaker Original - 9 years ago
If you don't like it, simply don't enter. I've never said that the work people do is worth only x amount or worth exactly a printer to us. Lot's of people are innovating for the fun of it and have to order and pay for all of the parts themselves. Just like I did when I got started. This wasn't a reason not to do it, though. I did it because I liked to build and improve 3D printers. I never expecby ErikDeBruijn - Competitions

Vacatures: Open Source Hardware / Software Engineer - 12 years ago
Wil je aan open hardware bijdragen en onderdeel zijn van een multi-disciplinair team van ontwikkelaars om de toekomst van 3D printing sneller dichtbij te laten komen? De missie van Ultimaker is om 3D printen toegankelijk te maken aan een breder publiek.

Re: Constant high-speed printing - 13 years ago
I should also measure still measure the speeds, but Martijn and I have been able to do a few prints about three times faster with the same level of quality. The attached prints look almost identical, but the one on the right was printed at 3 times the speed. Layer height is about 0.08... I'm not entirely sure. Sorry to be vague, I'm typing this in a hurry. Note there are many video's about Marliby ErikDeBruijn - General
Re: Pick and Place toolhead, STL files included! - 13 years ago
Because our pick-n-place partner was unreliable I renewed my interest in this subject. One of the baby steps I took was designing a tape feeder. It would be useful as a manual aid for hand placement, and I would gradually work towards full automation. I've actually placed a few components with a GCode file and a vacuum membrane pump. The pump's flow, however, oscillates too much. I'm looking inby ErikDeBruijn - Pick-and-Place Electronic Assembly (and robots!)
Re: Ultimaker: Een nieuwe, nederlandse RepRap afgeleide - 13 years ago
Quotezelf gebruik ik ook een aangepaste (interrupt-driven) temperatuurregeling, dus zo heel veel verschilt het eigenlijk niet. Interessant. Ik heb een oudere versie van de firmware ook al eens aangepast zodat hij vaker de temperatuur bijregelt. Als je PID instellingen niet goed staan (bijvoorbeeld als je het op een extruder aansluit met een andere thermische massa en wattage) kan nu bij het prinby ErikDeBruijn - Dutch User Group - Archive
Re: Ultimaker: Een nieuwe, nederlandse RepRap afgeleide - 13 years ago
Hoi Webspider, Ik snap dat jij in jouw geval meer vrijheid wilt. Al is je bezwaar over de firmware zowel terecht als onjuist Je hoeft namelijk niet 'onze firmware' te draaien, de standaard RepRap firmware werkt ook gewoon nog. Maar wat betreft je keuze van punt 2: ik kan die best begrijpen. Als je wat meer tijd hebt is het in elkaar zetten van een Mendel ook een erg leuke exercitie (heb zelf eby ErikDeBruijn - Dutch User Group - Archive
Re: Ultimaker: Een nieuwe, nederlandse RepRap afgeleide - 13 years ago
Denk aan zo'n 1200 a 1300 euro. Er komt ook een basic versie uit voor zo'n 1000 euro, zonder plastic, LCD schermpje, electronica en voeding. Verder willen we nog een 'hardware kit' bieden waar alleen de niet gelaserde onderdelen van het frame en de extruder bij zitten. Dit gaat pas veel later uitkomen, want we willen eerst goede complete pakketten leveren waarbij alles zo veel mogelijk op elkaarby ErikDeBruijn - Dutch User Group - Archive

Using Fuel injectors - 14 years ago
Paragon at Fab@Home wrote this, this should be worth further exploration! On finding this fantastic website I emailed Evan with some thoughts and ideas that I have been working on. One of these ideas was with regards to using an electronic automotive fuel injector as a depositition tool. I had four injectors purchased via eBay which where like new removed from a mini.

Re: Project: FiveD on Arduino - 14 years ago
Just a small update: I created a ReplicatorG patch to allow an uppercase "Start" to also work. It will probably take some time before it's integrated in the upstream version.by ErikDeBruijn - Firmware - experimental, borrowed, and future
Another extruder concept - 14 years ago
I've been working on the Bowden cable system, which works very well for me. But if you're nophead, you have concerns because it can limit the quality that you can achieve under some circumstances. I think that with his setup the bowden cable might have a visibly lower quality, in my prints I don't really notice it. BUT: I had no intention to go back to slow printing, but I do want to see if I canby ErikDeBruijn - Mechanics

Re: Help kickstart Lasersaur (FLOSS laser cutter) - 14 years ago
Can't tell because I don't know them personally. But we could definitely offer them that they can use our infrastructure to document it. Plus we already have most of the control systems to make a G-Code based laser cutter. So there could definitely be some "code" reuse.by ErikDeBruijn - Laser Cutter Working Group
Re: Help kickstart Lasersaur (FLOSS laser cutter) - 14 years ago
Yes, I thing both routes are viable but the are definitely for different applications. Laser engraving might be more appropriate for the smaller, low-power applications. Laser cutting for the bigger ones. For RepRappers the small version is a really cool toolhead to have... Plus wear laser goggles is cool I'd have to get warning signs for lasers and bio-hazard (NaOH and other chemicals). Oh, andby ErikDeBruijn - Laser Cutter Working Group
Re: Help kickstart Lasersaur (FLOSS laser cutter) - 14 years ago
I wonder why the CO2 lasers degraded... (300 hours of actual operation is not that bad, is it?) I would be interested in those lasers for mounting it on a RepRap. I acquired a ~1W diode laser myself but still need all the other stuff. But given the enclosure (or the lack thereof) I'm not sure whether it's very safe?by ErikDeBruijn - Laser Cutter Working Group
Re: Help kickstart Lasersaur (FLOSS laser cutter) - 14 years ago
Everyone should decide for themselves whether they think it is worth it. As you know, an open source system has inherent benefits. Also, availability of open source alternatives can stimulate the commercial vendors to innovate since the bar is raised (because of the alternative offering, but mostly because it decreases barriers for new entrants in the industry). There are definitely economies oby ErikDeBruijn - Laser Cutter Working Group

Re: Dutch User Group - 14 years ago
Hallo Auke, Als je in Utrecht zit heb je geluk. Daar hebben inmiddels een aantal workshops plaatsgevonden bij Protospace (ik gaf zelf de eerste workshop met Siert Wijnia). Er worden momenteel nog een groep Mendel's afgebouwd; de meeste mensen zijn nu met het printen aan het experimenteren. Toch is alle kennis daar aanwezig. Op een aantal dagen in de week is Protospace een vrije-inloop FabLab. Jeby ErikDeBruijn - Dutch User Group - Archive
Re: Complete Assembled Electronics Kit for RepRap for $215.00 - 14 years ago
Even within the GPL, GPLv2 and v3 are different when it concerns hardware. There's also a TARP but I don't think you can take something with GPL and license a derivative as some other license (almost sure you can't!). Kimberly, just make sure you post your native design files too. It doesn't matter whether ANYONE can open them. In that case the PDFs are a support for them.
