Thanks for the response Randy. I’m thinking it is a bent Z-axis screw. I’ll be sure to let you know if I ever get this resolved. Quite honestly, the reason I got the Lulzbot mini was so that I could have a printer that just worked and produced high quality prints. My 1st printer was a heavily modded Da Vinci. Currently, this print quality isn’t any better than that of my $350 printer, probably worse in all honesty. I’m seriously considering dropping my 3d printer hobby. I can’t tell you how frustrated I’ve been with this. I tried upgrading the firmware, turning the leadscrews so that the software didn’t have to compensate as much, tightening belts, looking for loose bolts/screws, nothing has helped and I can’t even stand to look at the prints my machine produces, the “quality” is complete garbage.
I had read in another post in this forum that there is a design flaw in the mini that causes, Z-wobble. Apparently there is a design flaw in the mini and most Taz printers. The axis is over-constrained by the bearings at the top and bottom of the printer Z-screws, as well as the two metal rods which also guide the Z-axis up and down.
