[Build plate cools down when print starts on Ultimaker 2+]

I changed heating wires and now everything is ok. Thank you.

[Build plate cools down when print starts on Ultimaker 2+]

I don't use other side firmware. I just updated my old one with Cura to Vers:_2.6.2   jul 4 2017

I slided bed manually and found the problem is in bad connection.

But there are no screws on the bed. So I'll try to change bed or wires. Thanks

 

[Build plate cools down when print starts on Ultimaker 2+]

Hi. I have problems with buildplate heating. It preheats well (I tried all range of temperatures from 60 to 115 C). It also keeps temperature well when it's raised. And it keeps temperature when extruder is hot. But after print begins buildplate temperature decreases to ambient temperature and corners begin to warp. When I put the print on pause buildplate temperature increases to working temperature again until I press resume.

I use Cura 3.2.1 but I don't think it's slicer problem. I unplugged heating contacts from buildplate and mainboard, cleaned everything with alcohol but it hasn't helped. Did anybody face such problem? Any advices?

 

[Hot end fan insufficient voltage.]

Hi, everyone.

I have Ultimaker 2+. It worked fine for a year, then hot end fan began to rotate slowly. I replaced it. The new one worked for three weeks, and then the same problem occurred, afterwards it stopped. I measured voltage. It was 2.53V both at the end of the cable and on the main board, instead of 5V as it should be. Have anyone faced similar problem? Any advices?

[Ultimaker 2 Extended +: PLA, first layer always warping]

Due to the lifting being so localized it looks like the glass may not be super clean. If you touch the glass, sometimes your finger oils can get on the surface and prevent your print from sticking in sections. If you find it not sticking to certain small spots on the bed, try really cleaning the glass well with some rubbing/isopropyl alcohol and it should be back to normal.

I would also level it just a touch closer, maybe 1/8 - 1/4 turn loosen each level screw.

Also that first layer looks huge. I usually have more success with smaller than 0.3mm 1st layers. or at least equal to my layer height.

Thanks a lot! It helped me in such case after a day of leveling the buildplate, changing nozzle and plate temperature, initial layer printing speed.
