Hello everyone and my first post.
My Creality CR10s prints perfect with PLA and a cold bed.
Trying to print ABS with a heated bed gave me problems and by chance I found the reason.
I level the bed and set the nozzle/bed distance to 0.1mm. As soon as the bed is hot this distance increases to 0.3mm.
That means in order to get a good print I have to set the distance with the bed hot. The problem with that besides burning youself
is when the print is done and I set the nozzle to the home position, the nozzle will dig into the glass once the bed is cold again.
I changed the initial layer height but it turned out not affecting the initial z-position.
What is expanding and how can I fix this?
