Warping Issues

[gustrowsky 0]

Hello everyone. I am trying to 3d print a part on my Anycubic Chiron. I am having trouble with the sides of the print warping which causes the whole thing to curl. I've tried everything recommended- glues, painters tape, heated bed. I've experimented with bed at 60, 65, 70, and 50 degrees, and the head temp at 180-190 degrees. nothing seems to help. I'm currently taping down the helper disks and it seems to be working, but i know i shouldn't have to do that. Any advice for this? I would really like some help. Thanks!

In 99% of all adhesion cases, the bed/nozzle leveling is not correct. I guess you nozzle is a bit too far away from the bed and the first layer is not squished into the bed. Try to level closer to the bed and print again.

 

I assume you use PLA, right?

Thank you so much! It must be the nozzle. I will change it and share my results. Yes, I use PLA.

Yes, but it is not the nozzle, it is the leveling where you set the distance between nozzle and bed, so no need to replace the nozzle if that was your intention or understanding.

And one more hint about leveling. When I level my printers I use a thicker piece of paper and bring the nozzle so close to the bed that I feel some good resistance when I want to move the paper under the nozzle. It should still be possible that you can remove the paper under it, but you should get the feeling that the nozzle would scratch on the paper. 

 

Hard to explain, but after some iterations you get the feeling for it. But remember when the first layer don't stick well to the bed, then the distance is probably still too big.

 

Additionally clean your bed with alcohol and if you have a glass bed, put a thin layer of glue stick on it. I usually make some stripes with the glue stick and then distribute it with a wet towel to get a very thin layer over the whole bed.

Thank you! I got perfect results when I did this.

I am glad I could help!
