Got a “E1 Heating Failed Printer Halted Please Reset” error message. But it’s been the same error message with multiple toolheads, and it’s hard to believe that they all have failing heater cartridges or thermistors. Any ideas about other issues that could be causing it?

Thanks,  
Wendy

See section 7 (“Connect Thermistors”) on this page:

Make sure your thermistor wire didn’t somehow manage to get disconnected or damaged.

Thanks so much! I’ll try that.
