Hey awesome 3d-printing enthusiasts! I was hoping you guys could help me with my 3d printing issue. I tried printing the following wallet case, but it came out being really slanted. I did not notice it until I tried to close the wallet. I attached pictures, the stl I was using, and the gcode for the printer. I have a FlashForge Dreamer by the way. And I was using 1.75mm PLA filament. Anything helps. Thanks.

Thats not a problem of your STL and it is not a problem of your printer, that's WARPING. Caused by different temperatures of the printed areas when they are cooling down.

PLA MUST have a very effective object-cooling and don't pick it off the print table before cooling down to the rooms temperature.

Perhaps you can save your print with heating it up to 70 - 90 ° in a oven and presse down with some ballast when cooling.

horst.w, I don't understand why the rectangular raft is crooked. If you look at the picture of the raft I added lines to show you that it is crooked. I aligned the right edge with a piece of paper and I added lines to the picture showing that it is not a rectangle (but it should be). The printed object on top of this, the wallet, is also crooked like this. Any thoughts? I don't think its warping since the print finishes flat. In fact it looks perfect but not a perfect rectangle. I will try printing again with 70-90 degrees C.

I hope there's a simple explanation.....but you say you're printing PLA, but your process name is R_ABS...which may indicate the process is for ABS. I hope this is not a case of using an ABS process for PLA.

Yeah I am using PLA settings. I just happen to not change the name to R_PLA. But this seems weird to me. I am at a lost. If it does it again then it has to be an axis alignment issue. But I remember printing something perfectly yesterday before this was an issue. Maybe S3d related?

Gantry is out of align. Meaning the gantry is not running parallel to the X axis. One side of the gantry/X-axis assembly is closer to the front than the other would be another way to look at it. I am not sure what the prescribed way to align is on the Dreamer. ON my Flashforge Creator Pro you have to grab each side and try to get one to jump some teeth on the belt in the needed direction.

Try a google search on aligning the gantry or you tube search.

wirlybird thank you so much for this! This totally worked. The gantry/X axis on the right side was half-an-inch back compared to the one on the left. I just had to remove the GT2 belt and reposition it and that fixed the problem. I recently had sent my dreamer to flashforge for repairs and I'm thinking that the belt somehow got shifted around and led to this. Again thanks for all the help!
