We recently acquired a new Lulzbot Taz 6 and after working with the single head extruder we decided to give the dual extruder a try and have run into some issues and need help. One of the issues we ran into I have figured out with the initial layer printing to thin so I adjusted the z height for the initial layer from 1.5 to 1.1 but the I’m still having other issues I can’t seem to pin down solutions to…
When the head finishes the auto leveling process the is sitting idle waiting for the bed to finish heating so it can start the T1(front) nozzle will pull the filament down till it extrudes a 9 to 10 inch strand of material onto the table and in the way of the bed track then retract the filament a little bit
When I try to print with only 1 color it completely skips the bed leveling process and then just starts trying to print to where the last z height it was left at (usually a few inches off the bed)
I notice that while the first centimeter of the print works fine after that the hot ends seem to be to close to the print and it seems to be touching the previous layer it laid down and leaves melted tracks through the material (it’s almost as if as it gets higher the head isn’t going up the z axis at the same height as it was when it was closer to the bed.
Right now these are the main issues I am running into and any help that I could get would be appreciated, Thanks.
