Anycubic Mega S seems to have developed some problems. Ran great right out of the box, but started to develop a severe problem printing even the simplest images.
The print head appears to push around previous layers and creates a "snowbank" near the edge. The print head then keeps running into it and screwing up the whole print.
The first two pics I provided are how the problem developed early and later on as well. The third photo is from an earlier job that printed just fine.
I have not done anything physical to the machine except clean the nozzle, re level and clean the bed.
Any ideas of how I can fix this problem would be appreciated.
BTW. If it is not already obvious, I am new to this #D printing.
Thanks in advance.
