Hi,
my printer needs quite long for heating up before the print starts. Today I measured 4:37 mins for the platform and 12:38 mins for the extruder. Especially the extruder needs several minutes to start printing from 97% of the temperature. The printer actually doesn't really shows that the extruder has reached the 100%. It fluctuates between 97% and 99% and after some minutes it just starts to print. Moreover I have some small brunings in almost every second print and some troubles to print inclined edges as shown on the pics. Moreover the peak of the part is more like a bigger blob than a sharp peak. Maybe the problem is related to a too high printing temperature? I just got my printer on Friday. So it is brand new and nothing should be wrong with it!
Best regards
Erik
