Review on 🌡️ Maxiwatt Hotend Cylinder THERMISTOR: Efficient Circular Temperature Sensor by Donald Vargas

They're really good, better than V6, MK10, Mosquito etc in my experience. Maybe only 40w but it heats up faster on than other blocks I own. with 50W or 80W cartridge heaters. I suspect it has something to do with the block having a built in annular heating element. It holds temperature better than other blocks and due to the nature of the built-in heater, it can maintain a stable hot-end temperature even when the pressure is constantly switching between different filament flow rates. I've noticed that some people on the internet are complaining about temperature fluctuations or PID overshoots. This is because they installed a new block and heater but did not run the PID tune command on their printer and then saved the new profile to EEPROM. This heater is much more aggressive in its thermal profile than block and cartridge heaters which have more bulk to deal with, so make sure to readjust your printer's PID settings after installing a new heater block. I really hope Maxiwatt releases an updated version that is reliable. Nickel plated copper so I can use this type of hot end with my high temperature (450C) printers.
