Heating Bed and Nozzle Simultaneously On CR-10 In Cura

On my CR-10, the nozzle heats up and then the bed heats up. This seems like a waste of time particularly in that I need to make sure the first layer of the print goes down correctly. After that, I don’t care. This sequentially heating dramatically increases my time investment in a print.

Warning: I’ve heard that the stock CR-10 power supply is trash and can’t handle this. I’ve been doing it for about a year (hundreds of prints) with no issue. Use at your own risk.

In Cura, go to Settings > Printer > Manage Printer > Machine Settings > Printer
