  1. I made a custom heated bead for my Ultimaker Original, it has worked for about a year with out an issue. Unfortunately the bed Thermistor shorted with the bed power cable today, neither the Thermistor nor the arduino mega was damaged, though I replaced both anyway. Now the issue that I have, is that the bed temperature shows approximately 800°c and thus causes a max temperature error, this is the same temperature that is displayed when no Thermistor is connected as well as if I connect 100k ohm resistor (its a 100k thermistor, so should show 25°c). This leaves the ultimaker controller as the most likely error source. I don't have one lying around, and the next possible replacement is in china, which would take a month to get shipped (I also don't want to change to a different controller since the system is made for a 19v power supply, and no one carries them anymore). Does anyone know what possible components on the board could have fried? or could I just switch to the sensor 2 on the board, and how would I set that up in the firmware? Thanks
  2. I checked the 4.7K resistor, that was what fried, thanks, would never have checked that... Unfortunatelly I seen to have another issue now, the printer pauses between each straight line for about 2 seconds... Any idea what could cause this? I already tried re-replaceing the arduino, that did not help...
  3. Its the exact same 100k Thermistor (I purchased a few of them when I upgraded to a heated bed) , I just replaced it with a different one in case the first one had fried.
  4. Anyone happen to know how many watts the Heater in the hotend of the UMO has?
  5. My printer is using 19.5V, since that the lowest I could adjust the Chinese 24V power supply with out using extra electronics..But no, am not have those kinds of issues...yet... Just ordered new heads with 12V 40W hearters but in retrospect i probably should have gone with 24Vs and mosfets instead...
  6. Yes, my fan probably blows on the nozzle too much... I have the UMO which had a 19V power supply ( i've since replaced it) I. I am guessing you are referring to the PID in the Firmware?
  7. Thanks for the info. I was hoping to go directly for the 40W since my current one maxes out at 230°c when using it for a longer duration. Unfortunately the ninja flex that I purchased needs 260°c to come out properly. In what way would I need to adjust the PID values?
  8. There are quite a few people who made mounts for the E3d V6 + UMO on Thingyverse most of who have instructions and information about this transformation.
  9. Just out of curiosity, did you purchase an original E3d V6? I am also planning on this, so I am curious as to the top temperature you can reach with the Head. As to your issue, did you change the extrusion rate? The MK8 feeder dumps much more filament per rotation than the original feeder (I use a combination of the two, so I didn't have to recompile the firmware for that modification). What changes did you make to the firmware regarding build plate size? Travel distances are defined in the Firmware (Configuration.h) with : #define X_MIN_POS 0 #define Y_MIN_POS 0 #define Z_MIN_POS 0 #define X_MAX_POS 205 #define Y_MAX_POS 205 #define Z_MAX_POS 200
  10. I am trying to add WiFi to an Ultimaker (Original) via Serial 3 on the Ultimaker 1.5.7 pcb. I measured the Rx/Tx pins on an oscilloscope an neither peeped. I have read that I need to enable this in Marlin via #define SERIAL_PORT 3 // this is normally set to 0 #define BTENABLED // enable this now the issue that I am having is all three of the marlin builder websites that I know of are not working. (Daid's, Ginge's and Amadee's) and I am looking for a Configuration.h that is setup for the ultimaker original as defined by the defaults of one of the builders. Anyone know where I can find that? (of course a solution to my issue that does not require rebuilding marlin would be just as good.) Also, I am sad to see that The tags don't contain "UMO".
  11. Amadee's builder seems to be working again. It is the last Firmware I used after I completed my Heated bed, It seems to be a branch from the Ultimaker branch, So I think I will use the configurator to build the configuration.h and then download the branch and build it manually.
  12. I am fairly certain I would have to anyway, as I dont remember any of the Builders to have an option for Serial_Port, My dilemma is where can I find the default settings for the UMO. As my latest searches have pointed me to the Ultimaker Marlin Branch in GITHub, which seems to contain the required Config file, my current question is, weather I should use the Ultimaker build or the latest Marlin build... The UltimakerMarlin branch does not seem to be very current, And I am unsure if the branch was made purely for the Configuration.h or if other files were modified as well...
  13. What do yo mean by parks? are the heads actually moved up and down separately from each other?
  14. Is it possible to use the UM2 Dual Extruder head for the Original, if I replace the L7812 on the board with a R-78C12 and use a 24V 30A Power supply? What about then hooking up a heated bed directly to the board as well, or would that fry something on the board? Also would there be any firmware issues If I compiled with the correct thermisters in Ginge's Marlin Builder? Wow, so many questions, but any answers would be helpful, thanks.
  15. Here is an old tutorial which I saved for when I finally do the upgrade myself: http://flashgamer.com/hardware/comments/adding-a-heated-build-platform-to-your-ultimaker

    From sclic3r to cura

    I usually change the speed directly on the printer during print if I feel the need (or want to play arround)
  17. After more than a year of having the parts laying arround, I finally decided to build a hot bed. I was about to go to Daid's Marlin builder only to descover there is a new one. Unfortunately I cant seem to find the termistor that I have in the list. I have the EPCOS B57560G104F. It is unfortunately not listed, though I did find a temptable at reprap (http://reprap.org/wiki/Thermistor#EPCOS_100K_Thermistor_.28B57560G104F.29) Any suggestions which I should choose?

    ethernet control

    has anyone had the idea to add a web interface to controll the UM? considering thatt it runs on an arduno , I dont think it would be that complicated...
  19. fboth do you think you could explain a bit more (with pictures) so electronical idiots like me can understand? thanks
  20. So I went and bought everything that I needed for this... (for those of you in germany, you can get custom sized schafts for not too much at Maschinen-Werkzeuge.com) and then I was browseing thingyverse and found among others this: http://www.thingiverse.com/thing:44078 anyone tried it with printed couplings? unfortunately I allready have the china couplings and they are failry good, but it would still interest me.

    Cura vs Kisslicer

    would love to see that new slicer.... currently I have extrusion issues with cura and cant use it at all, since I never know if what it outputs will be useful, and kisslicer does outlines, manytimes seperateing the same form into diffrent parts leaving gaps in prints, or rough edges.

    Slanted

    So for my third print I decided to try some thing more advanced.... after realigning the x and y axels, I printed http://www.thingiverse.com/thing:26586 from thingyverse. the base turned out absolutly fine, no slant noticed. then I printed the body and got this my guess is that a belt in the x direction is jumping maybe? Any help would be appreciated.
