      Hi Cyril

      P=UI=U²/R=I²R
      P is the power resistor,
      U is the input voltage, support 12-24v
      I is the current through the resistor,
      R is the resistance value of the resistor.
      24°C temperature measuring resistance：(R:10+-1Ω)

      Nozzle Compatible ：E3D V5 V6 MK8

      The temperature of the R value increases and becomes larger, and the P power becomes smaller.
      The core heated MCH ceramic ring supports a 500°C temperature rise.

      Because the cooling end Teflon material supports up to 280 ℃
      At the same time, the temperature measurement thermistor is NTC100K and supports 320°C

      Recommended operating temperature does not exceed 300°C

      The high temperature version H2-RPO hot end will be sold later
      Use PT100 for temperature measurement
      Support MAX 500℃

      Sincerely

    Hello,

    I’ve just received my H2 hotend. I installed on my Anycubic Mega S to experiment. The first thing I did was a PID autotune starting at room temperature (24C). Once it was done, I changed the values (M301) and saved (M500). The I started a new print with preheating the H2 but had an error for taking too long to reach the temperature. I did a second PID and the values were quite different. Changed and saved a second time. Preheated again (210C, PLA), took longer than normal but finally reached the 210C, did a small printed and all was fine (all of this through Octoprint).

    An hour later, preheated again, this time directly through the printer and twice, had the error of not reaching the temp fast enough. Just did a new PID ( Hotend PID: M301 P20.15 I3.84 D26.41). Again, it seems to take a long time to reach 210C compared to my normal heater cartridge (40W, 24V).

    I made no changes to the firmware.

    Are you able to provide any guidance on what I am not doing correctly?

    Thank you in advance,

    Claude
