Thanks for the feedbacka and pretty sure you are correct. I took it back apart and tried to square everything. I found the Z axis was squeeking, although running smooth. I moved the coupler up a bit off the motor, and that resolved the squeak. I lowered the limit switch and adjusted the bed, also heated and changed the nozze (I think there was something wrong with the filament, it made a mess in the housing). I also found an extruder issue, it wasn't feeding smootlhy....had to adjustd one of the gear things and slide it up, re-tighten-

Have had a few succesful prints finally! I hope I haven't damaged the bed, it has scratches on it, but things stick....for not knowing anything about printers had a crash course this weekend-
