I bought the TAZ 5 when it first came out. I have not been able to level the print bed and lets face it, LULZBOT has not been a great help. I am just about done with it and it is about to go in the trash. I am at the point of adding shims between the print bed frame and the main frame it attaches to try to correct a space between the extruder nozzle at the right front corner of between 1/32 and 1/16 inch spacing. And then I will have to probably shim the feet of the whole printer to get the printer bed level from left to right and front to back. I just want to know if anyone else is having the same problem with this 5 version as I am. Looks like I will ultimately be hunting for a new printer.
