Thermistor used is a NTC 100K thermistor (Beta 25/50 3950K-1%, click here for the R-T datasheet) Choose type 11 or 13 in Marlin firmware. This turns off the heater if temperatures reaches 150 C due to technical failure of your electronics (only meant as a safety feature, not for temperature regulation). For added safety all heaters come with a self resetting bi-metal 150C thermostat. The standard DIN466 thumb nuts used in all Voron printers used as spacers (VORON2) or levelling nuts (Trident, VORON0 and VORON1) can be used as guides to align the heater. The power is adjusted to allow running them at 100 % power without risking damage to the build plate instead of the 50% to 80% PWM limit recommended for the heaters listed on the BOM. They allow even heating almost all the way to the edges of the build plate. ![]() All heaters are optimized for our build plates shapes and hole positions. The silicone heatmats were custom designed by Fermio Labs and made to spec by Keenovo.
