mk3s post upgrade trouble with first, second, third layers
first post long time lurker ... (not really tbh)
i recently upgraded my mk3 to mk3s+ after having the parts lying around for ages and never finding the time really. the mk3 setup was filling all my printing needs.
however now after countless calibrations and only smaller parts successfully printed i am hitting a wall and not sure what it is and what my next step to troubleshoot should be. I suspect it has to do with the bed. maybe even as simple as lubricating the rods.
please see attached pics.
here i used the smooth sheet.
i cant get the texture sheet not even to work at all. the nozzle starts to tear away on the first layer during the print and messes up and gobbs /gibbs it up. having to stop the print then i will not say anything else otherwise i make myself a fool 😉 (probably)
any ideas?
Oh PETG at 230-245/80-85 (tried tweaking temps)
dried PETG two hours at 65degrees first to make sure its not some humidity in it.
RE: mk3s post upgrade trouble with first, second, third layers
changed the nozzle
reran every calibration
reran first layer number of times until i was happy
first layer on that part is fine from there on i guess the nozzle starts to scratch the surface i guess
also fast x axis moves make a buzzing noise
should i take everything apart and start from scratch?
