can't get anything back into calibration after switching materials. Bottom Layer is way off
I have had a horrible time after attempting and failing to print good quality abs or petg. but now when i switch back to my original prusa pla I cant get a decent bottom layer at all. rerun calibration over and over. my original offset was -.682ish and now it seems to want -.9 or more. cleaned the pei sheet with acetone and alcohol. but i dont get very good bed adhesion. cleaned out the tip with a needle, heated the tip to 295 and extruded a bunch to make sure that there is no abs or petg stuck. but I seem to get blobs during prints like ooooooOoooooooooOooOoooooOooooOo I can include pics if that helps but im almost out of my original prusa pla and makergeeks seems to suck. so I want to get it calibrated on good stuff if possible. Any thoughts would help.
thanks

Have you rerun a Z calibration recently? I make a habit to redo it every time I move the machine, seems like I always bump one of the Z screws.

Try doing a "Factory Reset" - Delete all data. Then Redo XYZ Cal and RE-set your Live Z Offset.
I chased my tail for a while but something was bad in the XYZ or leveling or something. The above made it behave correctly again.

I too am having this issue - after changing PLA from the silver to ivory or green I cannot get the first layer to adhere. I'm also getting the blobs.
I've attached a couple of pictures to illustrate the issue.
I'll try a full reset and report back.

So I solved my problems:
It's now printing brilliantly again. 🙂

High quality filament helps much too. I am plagued with issues like this with my el-cheapo filament... heh... I just can't help myself... Cheap filament is just so much fun to waste!
Once I build my Mk3, I plan on putting it on a sheet of glass, to give it a crazy-rigid platform. I'm not sure if I'm going to keep it where I want it or not though, where I want it, might cause issues with vibration/shakey-shakey.

I try to not make mistakes, but the decision is YOURS.
