  1. Well it finished without the major defects. I think we have another issue. It’s warping and drooping. Everywhere. You think my fans my not be working?
  2. I just cleaned both cores and did a fresh restart. We’ll see how it turns out tomorrow
  3. I have a number of different cores. I’ll switch them out and see if it’s there is any change.
  4. I’ll double check but I do believe I’m on the latest firmware. I have recently aborted a print. The underextrusion will be random when it happens. It was strange how there’d be underextrusion then noodles on the back of the model.
  5. Hi everyone, ive posted a few times about this issue that I’ve had with my UM3 and I’d really like to fix it now. After my printer has been printing a few prints and been on for awhile the printer starts doing weird things. The latest example is a 1/35 scale Jeep body with two filament colors. The first couple of prints were ok but I need to make some adjustment on supports. After that the printer started underextruding one color and overextending another. If I restart the printer it prints fine. Here is a pic of the start of a decent print and the second bad one. I restarted the p
  6. I have the DDG feeders in my UM3. The install was easy and I couldn’t be happier with their performance. You do have to change some settings via ssh but that’s not hard either.
  7. Did you get your head cleaned out? I ordered another head to replace this one. GR5 inspired and motivated me to clean mine out too. I destroyed the hardcore since the plastic on the hardcore melted quicker than the NylonX. The process was tedious with a heat gun from harbor freight. I ran into trouble when I didn’t realize I turned the gun on high instead of low. This resulted in desoldering the pins on the chip of the hardcore and melted the plastic on the lower bearing housing. I was worried I cooked the PCB on the head too. Since my new head won’t arrive until Monday I put this one back to
  8. Did this head flood happen on an S5? My head flood pushed the core over and caused it to short so I couldn’t heat it at all. Look on material or core menu to set the temp.
  9. I emailed fbrc8 and I’m waiting for a response. They do have a whole head with cable on their store listed for $408. The left core is the only one shorted. I may give it another try to remove all the NylonX but I just don’t have that much time right now.
  10. Ok so I’m going to get a new head. Anyone know if the s5 head will work on the UM3?
  11. The printer powered on after removing the head cable. Well I’m not sure what to do now. I was using only one core at the time but the second one is stuck in there too.
  12. So after a mega failed print and a jammed core my printer will no longer turn on. I found it with the display off and i could hear a ticking but I didn’t know where it was coming from. When i turned the power off and back on the tick went away but the printer would not come back on. I’m going to check the plug and power supply first but does anyone have an idea on what i should do?
  13. The print did come off the bed so I’m hoping it wasn’t a leak from the nozzle. I installed the nozzle with the included torque wrench. I think its 1nm ish. I had just received the core and it didn’t have a nozzle on it. I didn’t think i needed to heat it since I wasn’t taking off another nozzle. Ill report back once i get out of this mess.
  14. Ill start another for the power. Do you think a heat gun will work for the NylonX to remove it?
  15. I just had mine jam too using NylonX. The problem for me is that the Ultimaker 3 wont power on. It was strange i found the print hanging from the head, the back bed screw had come off, and the machine was just making a clicking sound. I had used fresh glue and the print was about 1/4 of the way done.
