I have been printing the Church Wall pieces this weekend and I am unable to get the two end pieces (Church Wall End v1.2 and Church Wall Ruin End v1.2) to print properly. I have printed all of the other pieces without issues.
The two end pieces get to the final stage (approximately 95% done) and the nozzle is finishing the top parts. This is where the weird behavior happens. The nozzle moves into part of the already printed model and ruins the piece. Sometimes the wall end is knocked down. Sometimes the wall end gets lifted up and become stuck to the nozzle and it continues printing a blob into the hole made by the nozzle. Either way, the hot nozzle causes a tear into the piece. I have tested both end pieces and both fail around the same time. I have not been able to successfully print either piece. Any advice would be greatly appreciated.

I’d possibly look at checking your zhop when retracted and making sure you’re not over extruding.

Could be an adhesion issue. Might want to try using a brim.

I will try to adjust the zhop setting. I don’t think it is an adhesion issue. I have successfully printed all of the other files without a single problem. When in the final stage of printing the two end pieces, the nozzle literally goes into an already printed area which either dislodges the piece or creates a spot where the filament comes out in a glob. Hard to explain, sorry. But thanks for the advice.

I was printing them one at a time to figure out why I had a problem. Someone of FB recommended printing them four at a time but spacing them across the print bed. He figured that sometimes working on smaller pieces does not give the layers time to cool off and they lift up and hit the nozzle. He also recommended using a brim. I took his advice and was able to print off both versions of the wall ends. Thanks everyone.

Glad you got worked out.
