Getting ready to put E3D’s “Silicone Socks<\/a>” on my E3D-V6 and thought, “hey, my kitchen oven mitts are silicone and I can handle 450F pots out of the oven, I wonder how much insulation the socks provide and does it change the PID<\/a>?”<\/p>\n

Two PID tunes later, one without the sock, one with, both starting from a room temp 22C V6 and using the g-code “M303 E0 S240 C8”<\/p>\n

Without sock:
\np 26.95 i 2.45 d 74.19<\/p>\n

With sock:
\np 32.75 i 3.54 d 75.8<\/p>\n

Which makes sense — p’s change means there is more error (heat loss is lower than bare metal), i’s change is the accumulation of previous errors.\u00a0 The derivative, d, stays roughly the same because p and i have similar changes in value.\u00a0 (I did poorly in calculus and am trying to explain this to people who wasted a semester and failed Calc I trying to understand how derivatives work.)<\/p>\n

What this implies is that the V6 extruders will heat more quickly thanks to the insulation and will cool more slowly after a print finishes.\u00a0 I can’t think of any prints where I changed the temperature of the print head during a print so this should “just work” after I update the PID values in Marlin.<\/p>\n","protected":false},"excerpt":{"rendered":"
