I am really struggling with my new Taz 3 printer. After 7+ hours I have one poorly printed octopus to show
Initially I struggled with getting the extruder to feed (did not realize I needed to use the pick to clean each individual groove out of the hobbed bolt after a failure) but now I think that is mostly resolved (combo of proper tension and meticulous cleaning) and I can get consistent test extrusions. After that was resolved I used the stock settings for ABS (230 nozzle and 110 bed) and on the first try printed successfully (although iffy quality and some gaps/etc). After that I revisited the bed leveling (using the lower than caliber, higher than paper method) and tried again this time with the recommended 85C bed temp and the twisted vase gcode and failed miserably for hours with no successful first layers. The extruded filament would not immediately stick to the bed, would drag around before eventually starting to stick, then jam (before the pause command could make it through the buffer to the printer)resulting in stripped filament and the exhaustive pick/brush/compressed air cleaning process.
Thinking the bed was too high I worked with leveling/z-endstop some more this time using a .305mm feeler gauge to try and be more precise than the paper/caliber method. At some point during these hours of failure the filament started extruding oddly. Instead of coming more or less straight out of the nozzle it immediately curls back under and onto the outside of the nozzle. It also seems like it is harder than it was originally to manually push filament through the heated nozzle by hand with the tension released.
Trying to print now results in a pile of stringy mess being pushed around by the nozzle. I am not sure if this is z-endstop/bed height related or nozzle related. Also note I am trying to use the bed at 95C vs 85C since the only success I had was at 110C
I am using IC3D filament in low humidity 65F ambient temps
