It did it on every print. I actually found the solution, however. I posted for advice before taking the entire thing apart for a thorough cleaning, just in case I needed to replace something while it was apart. During disassembly, I noticed a couple of things. 1. The Z rods had a bit of dirty build up in the recesses. Took them to the wire wheel and scrubbed them with alcohol. 2. The top carriage that loosely holds the Z rod in place wasn't centered. It's designed to allow plenty of front to back movement, but not enough left to right movement. With the nozzle close to
I've printed at multiple heights from the bed attempting to solve the problem. All have the same results. This one wasn't actually too close either. It was set with the .2 mm feeler gauge and the first layer was perfect other than a tiny blob where the layer started. What looks like a thin line on the skirt is actually a bit of left over clear filament mixing with the black.
This just started happening a couple days ago. Nothing about the printer has changed intentionally. The same GCODE printed perfectly 20 times before. Now it's over extruding like mad for the first 8 layers, then it prints perfectly fine for the remainder of the print. It does this on every single print now - old GCODE and new. I've seen a dozen posts around the internet with the exact same problem, but nobody seems to be able to offer a solution that works. The printer is essentially useless until I fix this. Possible problems: - The first 8 layers are over extruding, w
