Solved Print quality when scaling up model

Well after all this it seems that it was a stepper motor for the extruder causing all this mischief! The motor must have been going bad slowly because it seemed that it was getting progressively worse. In any case, I want to thank all of you for your help in nailing this down. Mark, you mentioned the extruder being close to the bed not allowing filament to extrude earlier on. Well this seems to be the case in the initial layers. What is the fix for this? I went searching the forum but couldn't find it so easily, I know I've seen it before but can't seem to track it down. Is it just a matter of changing my initial layer height? after awhile it seems that all goes well, but the initial few layers it seems the extruder is so close as to not allow filament out.
Thanks so much again for all the help, I was almost looking like Larry Fine of the 3 stooges with all the hair pulling before today.

 

Great thanks Mark. I can't wait to get back to printing again! Had to grind the keyway on the shaft a little further down towards the body of the stepper to accommodate the gear better. But now it fits perfectly. If anyone buys these motors I should say that I had to reverse the plug at the driver when plugging it in because at first it worked in reverse. Now it's working perfectly.
Fingers crossed that this will be it for awhile... Happy printing and thanks again all.
