I am at my wits end with this. I have had the Snapmaker 2 for a while now, and I am continuously having the same issues. I am having problems with the first layer of the 3D printer. I have manually leveled with the new firmware updates, and have changed out the heated nozzle for a new one. The best way that I can explain what is going on is that the printer is printing what seems like right on top of the previous line or at least very close to it. This is making the layer rise and creates different bubbling on certain parts.
I have lowered the speed of the initial layer as well as increased the heat of the bed and the nozzle itself. I have tried adjusting the extrusion width. Nothing seems to be working with it, and I usually spend hours trying to make a print that FINALLY gets the first layer right. Then when I try to go back and make another print it, I have to do the same thing all over again but it won’t work like it did last time.
Sorry for the rant, I am very frustrated and I can’t seem to find a way to fix what is going on.
