Chamber "Target temperature not yet reached" on Core One for ASA
I have been printing using ASA filaments for at least 4 days, maybe 12 hours a day. Everything was fine, until yesterday, I noticed one of the prints not running because the chamber temperature in my Core One was remaining at 32 or 33 C. The vent is closed and the rear fans are not operating, as normal when printing with ASA (I think). The room temperature is 22C. Eventually I got the “Target temperature not yet reached”-message. The heatbed is at 115 C.
I changed the filament to PLA and printed a different part, and that is fine. Today I tried ASA again, and got the same issue. Any suggestions

Do you have a way to measure the heatbed temperature independently? I'm wondering whether the built-in temperature sensor is malfunctioning and the heatbed is colder than it thinks it is. Although it would be an unlikely fault for the NTC (?) to give incorrect but still somewhat plausible readings -- but worth checking I think.

It does not have a chamber heater, so it may simply not be enough for the bed to reach the desired chamber temp. You can skip it, to continue the print and see if it prints ok.

I have printed ASA in a 12-14c room with vent closed without problems, it takes its time to heat up but it gets there and once there it prints fine. If it can’t heat up in 22c environment temp something is going wrong.

What's the Z when you start print? It usually starts with bed somewhere at the top. So it has to heat up only smaller space above the bed (it heats the rest of the chamber while printing when the bed slowly moves down).
