Hi, I try to print this model (http://imgur.com/vQwBFjF and stl file http://www.filedropper.com/budkahamulcowaver2original) but the thickness is very thin (less than 0.4mm) ... I had to print it horizontally otherwise, the nozzle width is too big vertically. I added some support to be printable. The result is not very good. Do you have advices to make the result more acceptable ? Thanks Gauthier

I cleaned the nozzle with this procedure : http://www.fablab-regensburg.de/wp-content/uploads/2013/12/Ultimaker-2-Nozzle.pdf It seems to be very similar to your method. I will ask to Sander Thanks for advice.

Hi, I tried to print something with laywood on UM2. I had no problem till a nozzle jam... I printed with default cura settings (210°C, 50mm/s). Do you have advices to avoid nozzle jam ? Thanks

Hi, I tried to use octoprint with UM2. It's normally compatible (https://github.com/foosel/OctoPrint/wiki/Supported-Printers). I used the Cura for produce the gcode. The port speed was 250000 baud. The print started but the Z level was not working, the nozzle temperature was set to 2°C... It seems to be really slow in comparison with print with sd file. Do I missed something ? Thanks !

Hi, How can you set the bed temperature, nozzle temperature and fan speed in Cura ? Thanks in advance

The bed leveling is a little tricky the first time. I wanted to be sure that it was well configured. When the glue was dried, I tried to add a second layer on top. The PLA was not sticking on the bed and I had to stop the mess... It was solved by cleaning the glass completely and put a new layer of glue. Is there some PLA colors who are more subject to warping ? I have pink, yellow, green, white, natural. Thanks for advices !

Hi, I received my UM2 last week. My first print (um robot) was just perfect. After this good experience, I tried to print a spool for laywood : http://www.thingiverse.com/thing:39564. I added some glue on the glass. It was a *big* failure. I tried to redo the levelling and it failed also. I noticed that the glue was dried and doesn't stick anymore. I cleaned the glass and put a thin layer of glue. The first 5 layers were almost good. The border of the spool's hub began to move up. It finished by colliding with the hot end... How can I avoid these kind of problem ? How can I change the heated bed temperature ? When use tape or glue ? Thanks ! Youtube link :
