Keep me posted on your new brass piston/plunger. I would assume it does need to be relatively snug but now air tight. The unmelted resin will work with the piston/plunger by forcing the lower (melted) resin out of the nozzle. Always keep the top portion of the barrel slightly colder than the bottom.
Firstly, I am not master in this field. However, what I see is the heater band wire directly connect to port 1 and 2 (~220V) of the PID controller. My concern is whether we get electrick shock when touching to the heater band during the operation (I mean when the heater bands getting hotter to reach the set temperature value) ???

@@nhanvo6390 no risk for 120 V. I don’t know about 240 V
