Just got my new Taz 5 for Christmas. Today I set it up and went through the “quick start guide”. When I got to the part where the printing begins (using bed_calibration.gcode) I ran into problems. I noticed right away that the first layer was very inconsistent with beads in places and very thin lines in others. I leveled the bed several times and checked the relative levels of the x and y axes using a digital micrometer. All of that seems fine. I raised the z axis up and did a bunch of extruding via the control panel in cura. That worked just fine, too (although I’m not completely sure what a problem would look like). I’m using ABS from IC3D. Originally, the temp was at 220 but I’ve subsequently tried 230 and 245 to no avail. In fact, the problem seems to have gotten worse because in the most recent couple of tries the “print” of bed_calibration produces almost no extruded material on the bed – again, this in spite of the fact that I can push the “extrude” button in cura and get a nice long thread of white ABS without any trouble. Any ideas about what I’m doing wrong or what to try in order to get this to work?
fwiw, I notice I have to push pretty hard in order to manually force filament through the extruder. Is it supposed to take a lot of force to do this or should it be relatively easy?
