I can check it, but today it suddenly works again..

I have tried this, and there is no image in browser. It worked fine the first week.

Our camera does't show in Cura anymore. Only the temperature info and remaining time. Tried two computers, and re-connected the printer. Connected via wire network. Is there a fix for this?

Fixed the heating bed by replacing PT100 element with a new one from Fernell.

We cant print because of the temp sensor fault every print. If I push the connector on the sensor cable side it will fail, so doing the resolder again. Measured the TP100 element(?) and there was 0,16 ohm or something. It should have been about 100ohm at 23-25 degrees C? What type of sensor is it exactly?

I took off the cable strain, and bent the small sensor wires while I looked at the bed temperature. I found a way to place it where the temperature shows correct and clamped it back. Seems to be a cable problem to me.

I have read about this feeder in the hack thread, so I'm trying to print iRobertl's version right now with a new roll with less curvature. We also have a ticking bomb with the "error - stopped temp sensor bed fault" On that issue we did the resolder and checked cable, but still the same.

We remelted the connector, checked the connections and wires, and it worked for the weekend, but today we are back with the same problem. It is behaving the same as the video again. Maybe there is harness problem in the cable? Or the bed itself?

We are back to print at 250 degree as a short term solution, and at the moment it works ok.

We resolder and tightened the wires, and it seems to be fixed. Thanks

I have now disassemble the hotend and done the procedure to get out debris several times from it and put in a new homemade machined teflon tube after the drawings from Ultimaker, and still have problems. A little debris was found: I can see the feeder struggle to put more force to push out filament as it is jumping when loading new material. It is not spinning on the filament, but kind of rewinds it. I also see that the curvature of filament is making more resistance feeding. My understanding is that there is still something going on in the hot end. When I had it disassembled and stuck the filament directly into the nozzle through the new teflon insolator it was flowing fine with temperature an 220 degrees. Right now we are at a point where we can't use the printer :/

Hello. I found this problem with our printer Loose connections?

We have the same problem with ours. Temporary solution we found us to increase the temp by 5-10 degree. If it starts again, increase more.

Now I am subscribed. I started a ticket 2 days ago with no feedback from support.

Sorry I forgot about this thread.. I have never printed ABS yet. Today I had to print with 255 degree blue transparent to not get underextrution. The first thing to try will be a new teflon tube. Will contact support about it.

Thank you for this information. It is possible that this could the reason for our problem.

Hi. Over time we have some problems with underextrution printing PLA. When UM2 was new it printed fine with default PLA settings with 220 degree. To fix this we went up to 230 degree and this fixed it for a while(weeks) Time goes, and went up to 240. Now it started to happen again and went up to 245 with good results. Printing only PLA and same color (orange and blue) from UM store. Could it be the temperature sensor that is messing up? Seems that the feedback could be wrong?
