Thank you all for the answers, I learned a lot!
I haven’t had access to the PETG from the first prints yet, but I had time to do some tests with the PLA.
The top one with textured plate and the bottom one with textured plate + 3DLAC. A slight improvement in both compared to “Cool Tack”.
In the two photos below, the test after downloading the model again! (I can’t explain what happened). I’ve never used the handyapp to start a print.
some voodoo or what?
