I need to print with very large nozzles, to print resistant pieces and to drastically reduce the production time.
I switched to Hemera extruder with Volcano, BrozzL and X nozzles, 0.8 and 1.2mm.
Now I have problems with heavy oozing in small part fills and on overlap (infill-perimeters).
This extruder (whit no PA), needs a very small retraction (0.40 / 0.60), if i go further, holes are formed in the seams. To improve the oozing problem I wanted to set the PA correctly as in the other printers with klipper that I usually use (standard 0.4 and 0.6 nozzle), but with 0.8 and 1.2mm I cannot push the printer at the speeds required by the Tower Test (100mms).
Any advice on which speed to use for the test?
Will PA be really useful with such large nozzles?
Sorry for my bad english.
