Thermal fuse on bed issues
🤷other
I built a 4.1 500 and built an enclosure for it out of Polyisocyanurate panels should be somewhere in the range of R-6 to R6.4 in terms of heat retention. Was printing fine all day after I let the printer cool to ambient temp and then did another heat soak for my new print. However when I didn't let it cool and then started another print I'm tripping the thermal fuse on the bed heater now. I had been printing ABS at 100 on the bed and now it makes an audible click at about 96C on the bed and shuts the bed heater off completely. The only difference is I didn't let it cool and I had added a few more clips for holding the panels on as they had finally finished printing. I'm assuming it is getting to hot for the thermal fuse as I hadn't had those issues before the enclosure and even when I let the printer cool off completely. However I thought those thermal fuses were rated up to 150C my toolhead boards at MAX are reading 88C and a low of 85ish and this photo was taken only after a 30 minute heat soak. Any ideas? I have already checked all my wiring and made sure they were secure connections and they were.
