Hallo Marc! Vielen Dank für das Lob! Die Kosten von ca. 750.- EUR kommen hin. Welche Teile sind nicht mehr erhältlich? Und welche Artikelnummern sind falsch? Ich wäre für eine Korrektur bzw. zumindest Hinweise auf Fehler dankbar! Viel Spaß beim Nachbau! Andreas Rozekvon Rozek - Altes Forum
Erstaunlich! Inzwischen ist die FTIStrap bereits zweimal nachgebaut worden - und ein Nachbau hat inzwischen ein erstes größeres Objekt gedruckt (beim anderen Nachbau gab es wohl ein Problem mit einer - vermutlich von Anfang an - defekten Heißklebepistole) Fotos der Nachbauten sind auf der Wiki-Seite zu bestaunen. Viele Grüße, A. Rozekvon Rozek - Altes Forum
Wow! Es gibt bereits einen ersten Nachbau der FTIStrap - siehe ! Wer wird der nächste sein? Viele Grüße, A. Rozekvon Rozek - Altes Forum
Tja, Viktor... (hoppla - Umlaute funktionieren wieder!?) ...was den Zeitaufwand angeht, gibt es wohl nur einen Weg: nämlich die FTIStrap nach Anleitung aufzubauen - da ist das Ergebnis nach weniger als einem Arbeitstag "garantiert". Alles andere dürfte mehr Zeit in Anspruch nehmen. Nun? Darf ich auf der FTIStrap-Seite angeben, ich wüßte inzwischen von drei Nachbauten? ;-) Viele Grüße aus Böbvon Rozek - Altes Forum
Hallo zusammen! Die Aufbauanleitung für meinen kleinen 3D-Drucker aus fischertechnik ist inzwischen vollständig und eine allererste Version der Steuersoftware ist ebenfalls verfügbar - alles ist über das RepRap-Wiki unter der Adresse erreichbar. Einem Nachbau der FTIStrap steht von meiner Seite aus jetzt also eigentlich nichts mehr im Wege. Viel Erfolg beim Nachbau! Viele Grüße aus Böblingenvon Rozek - Altes Forum
Guten Morgen! Es ist immer wieder faszinierend zu sehen, wie "klein" die Welt doch ist! Naturgemaess waren etliche Lehrer an meinem Stand - nicht alle haben von ihren Lehrfaechern her zu meiner Vorfuehrung gepasst, in diesem Fall haben sie sich aber dennoch eine Visitenkarte geschnappt, um sie spaeter an ihre Kollegen weiterzugeben. Jetzt bin ich gespannt, wieviele Kopien der FTIStrap es demnaevon Rozek - Altes Forum
Es ist geschafft! (aufgrund des derzeit herrschenden Umlaut-Problemes in diesem Forum verzichte ich auf Umlaute und Diakrit-Zeichen) Die vergangene Woche war richtig hart: ueber 400 Besucher haben meinen 3D-Drucker in Aktion gesehen und sich die Technik erklaeren lassen - und bis auf einen einzigen kleinen Ausfall (ein gebogener Heissklebestift hat sich in der Zufuehrung verkantet) hat das Geravon Rozek - Altes Forum

Hello - and all the best for 2009! It's been a really difficult month for me - but one with an interesting end: it seems that my "FTIStrap" will be shown on the "didacta 2009" fair in Hannover (see ) from Feb. 10th to Feb. 14th. You will find it in hall 15 at booth D65 and it will be presented by the "LPE Naturwissenschaft & Technik GmbH" (see ). I will visit the fair myself on the first dayvon Rozek - Reprappers
Good morning from Germany! Graham, I might be wrong, but you might have mixed up different controller techniques for different kind of RepRaps and RepStraps. E.g., my "FTIStrap" is controlled by a PC (rather than a micro controller), which sends the stepper signals to the RepStrap - just because I am using fischertechnik interfaces (the primary idea behind the FTIStrap was to use as many exisvon Rozek - RepRap Host
Hello Viktor! Great! Unfortunately, these sticks have a diameter of 11mm, whereas I am using a smaller gun which needs 7mm sticks. If I manage to visit an Aldi store, I'll still buy a bunch of these packs - in principle, I am looking for a solution to remelt unused hot glue anyway. With these sticks, I would have coloured hot glue, which is a nifty idea. Thanks for the hint!von Rozek - Reprappers
Hello Viktor et al. If you are interested in FischerTechnik, you may also join (or have a look at, at least) the "FischerTechnik Fanclub" at The FTIStrap is mentioned in the "Forum" under the topic "Modellideen"von Rozek - Reprappers
Good morning! Thanks for the honor, Viktor! I don't want to start a discussion about FischerTechnik, but: several years ago, FischerTechnik vanished from the toy stores (at least, many of them). Since then, FT is even more a tool for professional modellers. Nvertheless, anybody can order individual FT parts online (through Knobloch GmbH, the "official" FT distributor) For my little son (6 yearvon Rozek - Reprappers
Hello together! It took four weeks to receive the "fischertechnik designer", but it finally arrived. I now began to create a model of the FTIStrap in order to allow people to build their own copy of this kind of RepStrap. Please, have a look at The documentation is not yet complete - but the remaining descriptions will follow during the next two weeks.von Rozek - Reprappers
Geert, I *have* already built a RepStrap from FischerTechnik parts and it is working quite well using hot glue and a conventional hot-melt gun - see thread for some pictures. However, work on documentation and software had to be put on hold for a while because of other business activities. Hopefully, I will be able to continue working on it in the next few days. Just watch this thread or thevon Rozek - Reprappers
Oops, I did not imagine starting a discussion about definitions... To my current understanding, it will be sufficient to print the "plastic" parts of a Darwin to "qualify" as a "RepStrap" - ok, I will try that next week (if time allows) Sid: don't underestimate the stability of hot-glue if you use enough material (i.e. make the walls thick enough).

Good morning! As mentioned in another thread (see ) I am close to finish my work on a "RepStrap" built from FischerTechnik parts (and only a few other elements) - next week, I plan to set up the tool chain which will eventually allow to print "arbitrary" models. My question is now: what is the official way to "qualify" as a "RepStrap"? My FTIStrap already meets most of the project goals: * "Tvon Rozek - Reprappers
Oops, it was faster than expected: the spurious z step losses have been eliminated - but, well, corners could be better and lines perpendicular to the x axis are sometimes slightly off their foreseen position. Here are some pictures: Lines parallel to the x axis look perfect (i.e. y position is accurate), lines perpendicular to the x axis could be better (this might be a side effect ovon Rozek - Reprappers
Good evening! I am slowly getting better... I reduced the size of my test object in order to speed up printing - and had to install a fan because the (now shorter) lines did no longer have the time to cool down enough. As a side effect, the objects started to "sparkle" as the individual layers became more distinct and produced a "ripple effect" on the outside which reflects the light in manyvon Rozek - Reprappers
Sid, thanks - I found it. I think, I'll try it next week.von Rozek - RepRap Host
Good morning! Viktor: thanks for your hints - it seems that I'll have to learn taking photographs now ;-) Peter: currently, I have no idea of the material my hot glue sticks are made of. I am using a small Proxxon hot-melt gun (just because it is so small) and also use their hot glue sticks - I'll try and contact them, perhaps they inform me about the material. The translucency is pretty good,von Rozek - Reprappers
John, thanks for the information - I will have a look at that "Skienforge" (do not yet know what that is) Matt, thanks for your response - I know these pages, but they do not specify the format of the parameters.von Rozek - RepRap Host
Nophead, here are some pictures - again my excuses as the camera always focuses something else rather than the actual object :-( As you can see, the base is completely flat! The x offset has gone but the walls are stil la bit "bumpy" due to the limited glue flow control (I might have to reduce the flow a bit). The corners are getting better and better although there is still room forvon Rozek - Reprappers
Nophead, they can be easily removed and stay flat - I wipe the glass with a cleaning tissue (the same which are also used to clean computer monitors) right before printing. I do not know what is in the cleaning liquid, but I guess it's isopropanole. Wait, I have a new print ready - I'll take some pictures.von Rozek - Reprappers
Hello! Please excuse me if the following should be a typical newbie question - but I could not (yet) find the information I need. Is there anywhere a brief specification of the G codes and M codes (and anything else) which the host software sends to the Arduino controller? As I am controlling my "FTIStrap" (see ) by the host itself, I am planning to - extend the RepRap host software in a wayvon Rozek - RepRap Host
Ok, I think I got it: in x direction, the stepper sometimes(!) does not reach its final step. By simply keeping the current on a bit longer for the x stepper, I was able to get rid of the x offset - yeah! Now it's time to have a look at the software!von Rozek - Reprappers
Sorry, but I could not resist: now, that I am switching off the current through the steppers as soon as possible, the FischerTechnik interfaces are able to drive the FTIStrap for a complete print - here are my latest results: The corners are getting better - but still suffer from too much material. The repeat accuracy in y direction is ok, but in x direction there are sporadic offsetvon Rozek - Reprappers
Hello! I think, it's time to inform you about my progress: after building a slightly different extruder housing, redesigning the extruder feed and reducing the vibrations of the cartesian bot, I am now getting closer to "production quality". Here are some photographs of my most recent "print": The current characteristics of my little FTIStrap are: - position accuracy: approx. 0.von Rozek - Reprappers
