  1. Hi zoev89, I have an Ultimaker 2. Here's a thread I started with the details of what I'm trying to troubleshoot. Thanks for the schematic. The title says "3DPrinterFanHeater". Are you sure that's the correct circuit diagram? What are CONN_2 P1 and K1 CONN_3? Sorry my knowledge about electronics is still very limited. Thanks!
  2. I'm having issues with temperature fluctuations. I searched the forums and read about using a higher wattage heat cartridge on the E3Dv6 hotend. I installed the more powerful heater and now I have problems with the printer shutting off during heat up. I researched some more on here and saw suggestions about getting a higher power supply. Got one and now I'm searching for info on how to properly wire it so that I don't damage the Ultimainboard. Can you please share a diagram of how you wired the external mosfet to protect the printer's electronics? Also which mosfet did you choose? I got a 24V 20A power supply. Thanks
  3. Currently planning on making a higher power supply for my printer. Found this datasheet online. I think this topic can benefit having it. https://www.meanwell-web.com/content/files/pdfs/productPdfs/MW/GS220/GS220-spec.pdf
  4. Bought a 24V 20A power supply. Will be adapting it to connect to the Ultimainboard. I read in another topic that that amount of power is higher than what the Ultimainboard is designed to handle. What should I watch out for and do so that I don't damage the board?
  5. Hi forum, I have an E3D v6 on an Ultimaker 2. The electronics on it are the Ultimainboard 2.1.1 and the power supply's output is 24V 9.2A 221W Max. After having heat fluctuation issues I attempted to fix them with PID Autotuning but the problems remained. I did some searching here in the forum and read on one of the topics that a higher power heat cartridge could solve the problem. So I changed the ~20 Ohm heat cartridge that was running on 24V. I placed a 4.2 Ohm heat cartridge and in the firmware I changed the PID_MAX setting to 64. I reflashed the firmware and everything seemed to be working. With a multimeter I measured the voltage across to the new heat cartridge and it always stays below 7V when I heat up the nozzle in maintenance mode. Everything works in maintenance mode. I am able to heat up the nozzle up to the desired temperature. However if I try to print a file from the SD card the printer begins to heat up then shuts down. I also tried running PID Autotune with Printrun after installing the 4.2 Ohm resistor and got a PID Autotune failure message back saying the temperature got too high. I set the autotune gcode to 180C and monitored the temperature on the Ultimaker's LCD screen. The temperature shot up to 190C during the autotune attempt. Also the Ultimainboard seems to shut off right after the bed has reached it's temperature and the nozzle heat up is triggered to start. The red LED indicating that the nozzle circuit is on flashes on right before the board shuts off. Has anyone had this problem? How can I know if I'm drawing too much current and triggering some sort of protection designed into the electronics? Do I need a power supply with a higher rating? Thanks for the help.
  6. Thank you for the info geert_2. Do you suggest any LEDs strips available for sale that should work better / last longer with the Ultimaker2?
  7. Hi guys, I have an UM2 and its LEDs haven't been turning on for a while now. I finally took them off and would like some help if possible. I have checked the board and when it's on the pins for the LEDs are giving 24V. I pulled up its report and this is the info it gave me: Machine on for: 2588:20 Printing: 2174:48 Mat: 3854m What do the first two mean? Is the format hours:minutes? Attached are some pictures of the LEDs, One of the wires leading from one strip to another has its insulation stripped off some how. I'm not sure if this is the issue because I checked the strips continuity and all segments are fine. I did this by scraping the glue off of the back side of the strips where there are visible electrical contacts. I checked with a multimeter. Even where the LED's contacts are really brown (in one picture) there still is a working connection there. As for the brownish aspect of the LEDs, I think this might be a sign that they have gone bad. Does anyone know what this might be? Thanks for the help.
  8. Thanks for helping gr5. I upgraded my UM2 with the e3D Titan extruder and hotend. My goal is to optimize print time depending on quality. 0.8mm nozzle x 0.4mm layers x 100mm/s speed = 32mm^3/s That's way above the 10mm^3/s throughput you talked about for the 0.4mm nozzle. Is there a way to calculate the max throughput for different nozzle sizes? It's finally good to know that the UM2 black feeder should be kept around 5lbs. I think I might have been printing too fast for many of my prints. Too many failures made me buy the e3D upgrade.
  9. Shouldn't it say "a bit below my recommended"?
  10. I'm planning on testing speeds for my printer so I did the table in the above post. Is it safe to say that since the throughputs are low when printing with lower layer heights, then I can increase the speeds drastically?

  12. Hi gr5, Now that you mentioned it, I noticed that the nozzle is visibly further to the right in comparison with the original UM2 hot end. I'm guessing I need to adjust Cura for this? I don't know how. Do you? Thanks
  13. OK. Thanks. Started this topic: I checked the machine settings. The width and depth were set to 230 x 230. Reduced it to 205x205 now. Will check if the problem persists. Thanks again.
  14. Hi community, I've upgraded my UM2's extruder and hot end to the e3D titan kit. For some reason my prints are showing up centralized in Cura (15.04.6) but on the print bed they are off to the right and for one print all the models were yellow in Cura but then during the print I got an error message that the printer tried to print outside of the print area. Any tips for what might be the cause of this? Thanks
