This thing is amazing! I used it to lighten up the effector on my Anycubic Kossel Linear Plus delta printer, and it was a huge improvement. Not only did it lighten it up (making for faster print acceleration and speeds), but it heats up *super* quickly! I did 400mm/s 0.30mm layer prints at 4500mm/s2 acceleration and this thing never showed the slightest sign that it couldn't keep up! Pro-tip: Use Deep Cool Z5 heatsink compound (rated for 300C!) between the heater and aluminum and in the hole with the thermister.
Very nice as described.
