I have received my Taz 5 printer a week ago, I had done printing (around 5 - 6 models) using PLA material.
Recently when I have tried using ABS material, I saw the very first layer of the print is getting ripped off all the time and
messing up the nozzle from outside.
At first, I have tried to clean the Heated Bed PEI surface with IPA(as per the manual). But problem was still the same.
Then I have tried to calibrate the Y axis and found out the clearance between Nozzle and the PEI bed is uniform at the corner
but as I go to the middle of the PEI surface it seems to reduced gradually.(With heated bed @ temperature 110 Degree)
Because of that the layer printing is messed up all the time. Would you please help.
What could be the possible reason for the PEI bending?
I read some posts from the forum and I guess it would be the non-uniform distribution of heat on PEI surface. Also one post suggest the
temperature for ABS material should be set to 85Degree instead of default setting 110degree.<Post: TAZ Heatbed: Use 85C not 110C>
