  2. Hello, I have experieneced the same "Arrrghhhhhhhh!' as you - that 'Max Temp Error' message on the ulticontroller is a rather hidious beast. I would say that 4 out of every 5 prints were failing, short prints of 1 or 2 hours would be OK but anything over this print time would fail - very annoying when a 10 hour print fails at 9 hours "we were so close but alas it was not meant to be". I checked all wires and re-plugged them in etc and then it would be OK for a short time but then same maxtemp error message would revist me like Crugger - whats going on here??????? Then I looked at the fan and thought could the fan be fluctuating a temp sensor or similar - so I decided to turn the fan off & try a 14 hour print with a slow to medium print speed (60-100) 14 hours and 12 minutes later a little bit of beauty lay on my ultimakers bed no fan = no 'max temp error' = no print fail So prepare your files in Cura (print slow) - Turn off the fan in advanced settings, prepare G-code and save its path to SD card - pop that little SD honey into your Ulticontroller and let the good times roll. nb: if the fan is esssential to your practice then maybe turn it down from max (255) to medium (150 or so) as this will at least reduce the regularity of this error message appearing. But I have found that no fan has produced better prints with less warpage as they are curing to air temp which is as even as you can get. Warm Regards from England
  3. Dear Daid & GR5, Firstly, thank you very much for your replies, greatly appreciated. I double checked all pulleys with an allen key and all were tight as could be. I marked the pulley and axels with a marker and the smallest slight slip on the rear x axis - although the grub screw on this pulley was super tight (?) bad grub screw on pulley? So I un-screwed the grub screw on said pulley & discovered that it was covered in grease/oil - which would of prevented it from maintaining a good grip on the axel - so replaced it with one of the spare 'non-greased' grub screws that came with the ultimaker kit. Printed the thingiverse '20mm test cube' and the slanted walls are no more. Thank you ever so much, you guys are 3D dudes for sure Kind Regards, Kevin
  4. Hi, Received / built my Ultimaker in April 2013. All my files originate from Google sketchup, exported as STL, opened in Cura, printed in quickprint mode set at ‘normal quality mode’. On day one I initially printed the robot and two prints successfully. But after that all my prints started being printed slanted to the left. I have read other posts regarding this slanting print error so have done the following: 1) Re-positioned the x-axis pulley to ensure that the short black tension band is not touching the wooden back wall. 2) Added M3 spacers between the wooden back wall and black plastic risers 3) Loosened the x-axis motor bolts, pushed downward on the motor to create greater tension and then tightened bolts, this improved the slanting problem slightly but by not much. 4) Checked that all pulleys are tight on metal shafts. 5) Checked that the print head manually freely moves in both x and y directions without friction. 6) I have tried printing different files - my own files and a '20mm test cube from thingiverse' but the problem persists with all, some worse than others. On some occasions the extremity of the slanting has lessened during the print (see photo) (?) I am new to 3D printing and for the last 2 days have been unable to print anything with a true right angle. I now unsure what to do and any advice would be greatly appreciated, kind regards, Kevin http://oi37.tinypic.com/2dw5m4m.jpg
