Purge okay but not extruding during printing I am new to 3D printing and have a newish Eryone Thinker SE.  Its been printing fine with some Eryone Glitter Black (EGB) and I'm happy with the results.
The spool has now finished and I'm trying to use some black Tinmorry and/or Sunlu - both rolls are displaying the same issue.
I can load and purge the new filament just fine but starting a print immediately after results in no filament being extruded.
I have unloaded/reloaded, purged and retried a few times to no success. I also switched back to the take end of the  EGB with success.
Extruder temperature is 205 °C. Is this just too cold for the new spools?
So, I was able to fix this (or it fixed itself overnight as these things sometimes do) with a 5°C increase in extruder temperature to 210°C.  The Sunlu PLA filament specifies 200°C - 230°C as its print range.
I followed the advice of a IRL friend who suggested &quot;What happens if you raise the z a bit so you can see the nozzle and keep raising the heat until it starts to come out on its own.  Check temp and then run a print at that temp.&quot;
I only needed that 5°C increase before I could see it oozing.  From there I was able to successfully print a calibration cube and further model.
