I got a Da Vinci mini 3D printer recently and I am very happy with the results. However, recently the printer has stopped functioning properly. The printer will print the first layer, and then immediately redo the purge and make a thudding or clicking noise. On the troubleshooting website, there were a couple of solutions, but after trying all of them multiple times, none of them would work. I was wondering if anyone had any suggestions on how to fix this problem. Thanks!
