It happened to me a lot of times, you just need to refresh browser to fix it. It happens when you do firmware restart when the printer is hot.

这种情况我遇到过很多次了，只要刷新一下浏览器就可以解决。当打印机很热时重新启动固件时会发生这种情况。

@skyaee thank you for the tip with the reset after a high extruder heater temp. pls write here only in english... i will reopen this bug report and try to fix it.

Ok. I found a bug in the API init process. After a firmware_restart/restart it always initialize the extruder>can_extrude value as false and don't update it after that, only you pass the min_extrude_temp. So i added a "hack" to reinit this value after a short delay.

A real fix of this, have to be implemented in Moonraker/Klipper, but it would work fine with my fix in Mainsail.
