  1. found one on ebay, ordered, waiting. every little bit could make my UM better. not expensive (5$), maybe should be in the UM kit from the start...
  2. hi, seems to have the same problem. before switching to v2, can you show how you keep the peek cooled and why this helps? thanks!
  3. hi Umakers, after several days fighting with Z axis wobble i put down this one: http://www.thingiverse.com/thing:182295 it's a little piece to help Z axis top end to keep its place, and togheter with the brass z nut movement COULD help to reduce vertical wobble in printed objects. It seems to work. does'n eliminate it but seems to reduce it. Remove vertical wobbles in printed objects seems related to several different things: z axis problems bed problems under/over extrusion problem slicer poblems (netfabb seems to produce the best slice in terms of vertical wobbles against Cura. need
  4. Netfabb also (if you select random start in a submenu) can start every layer in a different spot. (the problem with netfabb is still the retraction than still isn't working good). On my last print yesterday night, the test cube was quite good, no more 3mm wobble but a lot of ooze from every layer starting point. So, even starting layers in different spots (the way you told cura works) netfabb seems to produce a cleaner print. I do not understand. really.
  5. well here I am, reporting of a Z wobble problem too. after months (18) of use, my UM started to print with a significant wobble on the Z axis. Read the forum, analyzed the hardware, scream like mad and tried several things: 1: free XY play for the brass nut. some file work on the wooden parts and the Z nut can move freely in ther XY domain (weird.. when I built the UM the z nut was blocked but the printing was really good with no wobble) 2: printed a add-on to guide the z thread and eliminate axis wobble, worked quite good (i will place it on thingiverse ASAP) but not resolved 3: quit C
  6. tried bendlay without heated bed, confirm that it doesn't work well... wait until HB is available... or switch to TGLASE, not bendable but cristal clear. strong and print on cold kapton tape
  7. well well well, Last weeks I sailed the web searching for new filaments for my UM original. Until now I found and bought and tried a lot (no heated bed, just kapton tape or blue tape): Taulman nylon 618: warping , quite elastic, great strenght. I need more time to play with it and test different Temp Taulman nylon 645: fantastic. less warp, incredible strength, great cleanliness. no problem about sticking on the kapton tape. still playing with it Laybrick weird filament, stick well on kapton, bound well between layers. more temp mmeans more roughness on surface and more brown colour (i
  8. arieccomi qui dopo un bel pezzo... sono quello che ha aperto questo thread... e sono di Roma... @Proteus3D, io con la ultimaker mi trova strabene, ho letto ovunque (su forum di altre stampanti e anche su questo) di moltissimi problemi ma confesso che da qualndo l'ho montata (ormai 18 mesi fa), il tempo di settarla e fare un pò di prove, roba di una giornata, e poi via a stampare! sento un pò la mancanza di un heated bed ma al maker faire ho parlato con i ragazzi di ultimaker che mi hanno detto che è in preparazione anche una versione addon x la UM1 per fine anno oinizio 2014. per il rest
  9. lascia perdere replicatorg... scarica cura rc4 , installa in firmware tramite il setup di cura e inizia a divertirti...
  10. @lucamaz Errore di battitura... Ho dato il RESET... Ovvero il tasto reset machine settings. A quel punto nel riquadro gcode start che è nei settaggi avanzati mi è apparso un lungo script gcode che la macchina mette prima della stampa vera e propria e pare abbia risolto i problemi
  11. It is an italian seller on ebay. 800gr at 16 euro. No rolls, filament seems a bit oval but have good viscosity and it is very tenacious after printed. Very vey few little bubbles inside. I m happy You can find it on ebay searching for 'pla 3mm filament' he lives in catania, sicily. I heard from another friend that he bouht a fantastic filament from filamentprint. He is really happy, i will try it in the future.
  12. Sorry to hear that. You are in the same situation i were, and I know it's reaally upsetting... Only good news is that cura works with the blank preview too, so you could still use it. Sad but useful. Set python.exe with administrator rights? Checked driver for graphic card? If it is an ati card you could remove the drivers and use an old version ( now we have 12.4 you could try 10.something, i read somewhere that w te best version regatdin oengl support) Removed blingbling win 64 transparent deskop and set it to basic colours? Tried a different ( better an nvidia) graphic card? Good luck
  13. Io e antiklesys ci stavamo pensando, anche x l abs. Hai fatto un progetto tuo o hai costruito uno di auelli che si trovano in rete? Dacci le indicazioni che hai seguito tu che quasi quasi mi metto e lo aggiungo, farebbe compagnia all ulticontroller e avrei la ultimaker definitiva!!!
  14. Ciao, In realta io non ho fatto nulla dal lato hardware se non usare 4 molle prese dalle mollette dei panni come tendicinghie... Il resto è stock e va bene. I problemi li ho trovati tutti nel software. Ho smadonnato con netfabb per un mese fino a che ho dato il rest e mi è cambiato tutto. Mi sono trovato un pezzo di nuovo codice nel start_gcode e ora va bene. Io poi non ho pretese di qualità superlative ma mi servono stampe in tempi rapidi quindi se stampo anche a0.2 ma con lo skin / half layer vado benissimo. X le cose di tutti i giorni poi uso cura...
  15. I am the old 'blank screen' reporter... I don't know how I solved, I tried everything and Daid told me everything he could to help but nothing. I solved when I disinstalled some software from my system during a normal clean routine of my pc. from then on everything went right. Anyway you have to check your video driver and keep it updated. I read that ATI cards give some problems with opengl and a new driver can help. at the same time any modification I made on videocards parameters didn't work. good luck, cura is a fantastic software and can make your 3d printing life cozy and warm...
