Unable to maintain target temperature with big nozzle

  • I have tuned the PID to 280°C of my volcano hotend with 1.2mm nozzle and 24v 40W heater cartridge.
    Now I want to print at 40mm/s 260°C but the hot end is unable to maintain the target temperature because of high flow of plastic. (layer fans are Off)

    Is there any work around ?

    I've never used a Volcano, but here are some suggestions:

    1. Use a silicone sock on the heater block.

    2. Turn the PSU voltage up a little (maximum recommended for a Duet is 25V).

    3. Get a 50W or 60W heater cartridge.

    4. Use the lowest M307 dead time setting that doesn't cause temperature oscillations. That will help the PID react faster to changes in flow rate.

    1. Using the sock
    2. I will try
    3. ordered a 50W cartridge, never seen a 60W can you point me to a shop please ?
    4. lowest value I can use is D3 for the dead time
