je ne parle et compris pas tres bien le francais..(mots speciale) peutetre traduire ca en englais. il y a beaucoup plus les utilisateurs anglophones. Je peux dire que l ultimaker est une machine tres versatil. avec un peu de travail en étalonner, on arrive a une qualite utilisable tres vite. pour modeles avec precision 0.1 on doit savoir beaucoup sur filament. diamètre et température.. doit connaître sa machine tres bien.

wo genau indr schwyz? i bi vo basel

On my machine i have this "grippy-surface" problem too. your lucky to have this on the invisible back side :mrgreen: first i though it was intolerant filament. because other layers come out perfect like yours.. it tends to settle only on outer walls that have other geometries right next to it. (thin walls too) i didnt found a way to have it solved but printing very slow... and thats not realy a solution.

maybe you are running the cura app from its installer file .dmg? i know quite some windows users that tend to do that on a mac. if yes move Cura to application folder and then start it from there. Also check if the stl too big or has flaws in its first few layers.

My Progress building a DI Wirebender machine.

I had quite some good prints now and the problems didnt came back.. so i guesss it was eigther EMI, Printsspeed, or temporary Gcode failures.. on Hardware side, i didnt change more than the cables... The Rods are lubricated with sewingmachine oil.. We had EMI problems in my printer workshop in Newzealand. but only on one of two Ultimakers. Endstopcables were put directly on axis stepper motor cables and that will result in errors... It was solved easily by redoing the wirelayout on the bottom of the ultimaker.

Reinstalling solves the slowness and the open file location for me.

Newest Cura on MacOS 10.8.2 "open file location" function doesnt work anymore.. dont know why. i didnt change anything. Also the finder dialogs are realy realy slow. I wonder if delete and reinstall will help. first i will try delete the pref files. thers definitely some cache-thrash-data or similar clogging up the app... i miss the speedy workflow it once had. :cry:

show me plastics that doesnt come from china :roll:

hi everone I recently saw this online: http://www.nanopool.biz/de/ http://www.nanopool.biz/en/surfacess/glass-ceramic they got this special coatings that could be intersting for our build plattform experiments.. ...coat aluminium with liquid glass, maybe creating interesting temperature and adhesion properties. :ugeek: Tell me what you think.. i try to get some samples from the company.

Di wirebender part...

For monting the Steppers on the back of the UM and rotating them downwards by 90degree... I found these online.. https://sdp-si.com/eStore/Direct.asp?GroupID=1124 can these work for us or are they not precise enough?

Can you maybe add a ticking box in the preferences of cura, so it starts with a new empty editor if wanted. not loading anything in background...

same here.. Problem solved like this: not buying from the scource again... (emailed them about the incorrect tolerances) Installed a ID 4mm OD 6mm PVA Bowden tube as a second extruding setup. Now i can swap the nozzle between my two bowden tubes... Of course you have to swap on the feeder side too. Later im going to add a second nozzle if helping software changes are in sight.

theoretically mixing the 3 main colours gives black but most of the cases its more of a grayisch brown...

Danke. Hab nun meinen 4mm schlauch... ergibt nun ein dualstruder setup mit nur einer Düse. So kann ich schnell wechseln.

can you specify what computer and operating system? i know some windows machines can have a hassle with the USB drivers needed to connect. on my mac there were other problems like running the software.. but runs fine now.

just made it work with my ultimaker.. no firmware changes. copied the .hex files from Cura into right place in repetier.. /Applications/Repetier-Host Mac.app/Contents/Frameworks/Sparkle.framework/Headers other settings i made. Baud to 25000 stop bits 2 Parity None Transferprotocol Auto No pingpong no firware ok sending

I saw this recently. was amazed.. think about 4 or 5. not just because we can but because CMYK! about colour printing. (cyan, magenta, yellow, Black/white) but needs complicated nozzle integrated mixer. all in all we could head towards full colour printing earlier than thought. :mrgreen:

Stell sicher, dass wen das ding fertig ist du dich mit den verschiedenen plastik materialien auskennst. Damit nicht mit falschen temperaturen einiges kaputtgeht... ausserdem Lebensmittelecht sind die standard materialien auch nicht. Ansonsten, mit ausreichend englisch Kenntnissen bekommst du hier alles nötige im Forum und auf Wikipedia. Ein paar "essentials" zum printen damit der Ultimaker so richtig in die gänge kommt wären da noch... gitbs n extra tread hier im forum. Dann gibts anlaufstellen in Zürich und Basel. Fablab Zürich.. gestern eröffnet und Hyperwerk in Basel inkl. meine wenigkeit. :ugeek:

good point.

i think you also need the filament drive mecanism. wooden parts and ballbearings. (there where the stepper motor sits and the extruder-drive-upgrade goes in) you find the building instructions on wiki helpful i think. its not in the shop like this.. but you can email the sales team and they will find a solution for you. you could source these parts yourself.. dont forget the small extruder pulley. there are free lasercut drawings available online on thingiverse. you need 8mm bitchwood 4mm delrin or acryl glas 8mm delrin or acryl glas

Can you paste the start.gcode you use? i never got to test netfabb because its not free.. if you have the same firmware that Cura would use, i would test to copy paste some lines from the start.gcode from cura. maybe that works out. It zeros the printhead to the front left then pre-extrudes a little and goes to the middle of the plattform to start the print. hers my start.gcode --------------------------------------------- G21 ;metric values G90 ;absolute positioning M107 ;start with the fan off G28 X0 Y0 ;move X/Y to min endstops G28 Z0 ;move Z to min endstops G92 X0 Y0 Z0 E0 ;reset software position to front/left/z=0.0 G1 Z15.0 F{max_z_speed} ;move the platform down 15mm G92 E0 ;zero the extruded length G1 F200 E3 ;extrude 3mm of feed stock G92 E0 ;zero the extruded length again ;go to the middle of the platform (disabled, as there is no need to go to the center) ;G1 X{machine_center_x} Y{machine_center_y} F{travel_speed} G1 F{travel_speed}
