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
