Bad news on the 240V conversion, but I do appreciate that Bambu gave a specific technical answer. Someone asked an engineer and got an answer. That is unlikely to happen when the respondent is executing a script in an Indian call center.
The 220V system could also use lower ampacity wiring. It probably doesn’t, but could.
While the 230V may not be for sale in Canada, I’m waiting to hear final confirmation if I can switch mine over. They sold me the 230V AC board, after all.
Bed heaters are simple power resistors connected to mains, so at 240V the current is about twice than at 120.
240V printers beds heat faster and consume more power.
The current does double. But, P = I^2 *R, so doubling the current quadruples the power. Being sloppy with terms on a forum just confuses people. In the real world, it starts a fire.
Quick note here regarding swapping over to 230v, the response I got from support:
"Please still buy the Chamber Heater Unit (For 220V Printer) and heatbed (For 220V). Only the AC board is not enough. "
Dunno how much those parts are yet, but I think I’ll be sticking with 120V operation. Warmup time isn’t an issue, the only remaining issue is running a new circuit and then finding a beast of a UPS in 120VAC.
Reading the details regarding this have me disappointed. Support is telling me my H2D which has yet to be shipped (Canada) will be capable of running 240V This unit was advertised as being capable of running on 240v and now I’m in limbo wondering if my I can use my 3kVA 240v UPS or if I will have to order something else. What a ■■■■ show.
