Important news about the Bambu A1 printer....

[Dabbler]

It appears there is a problem with the bed heating cable on some A1 printers, so now there is a general advisory to stop using them (by Bambu labs).... They consider it a safety issue. Have a look at their blog, but refunds are possible and in March they think they will have replacement cable/heater kits available for those not seeking a refund.
