Ive been having problems with a certain print getting to the second layer and for some reason just cant maintain setpoint. In my case the nozzle temperature is 205 for all layers, and it happily prints layer one without any problem. The temperature trend looks normal with a slight dither. Layer two starts, and and the temperature drops (not the setpoint, but the actual) to around 195 and flatlines (no dither) I lowered the speed to 20% to make sure it wasnt just running too fast, but even super slow it cant keep up.
I dont see anything in the G-code out of place where the second layer starts, so im flummoxed. I am slicing with Cura 4.2.1
It seems ive had this problem before, and I at the time I think I just resliced from scratch using a previous known good print, and the problem stopped. I think
It just somehow seems to be print dependent, though I cant fathom any reason why.
Any thoughts appreciated....Henry
