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.
It isnt the voltage ya need to worry about. Most modern boards handle a variance in voltage. The frequency is what hertz… Us and canuckian power is 60hz. British standard is 59 and iirc oz and kiwi country are 50hz as well. Anything with a motor will have issues unless you get a fairly high end power converter. I used to travel back and forth across the pacific and killed a fair few electronic items inmy day… Some of wm even died because of wrong plugs. Most were just me being a bit too aggressive with switches
Hey guys, this is the answer. We’ve been through these discussions with the X series too. The problem is the power is used different ways in the printer. Some goes through the power supply which probably can be set to 120 or 240V or may just not care.
The problem is the heaters. They are spec’ed for the target voltage and have to be replaced if changing what voltage you want to run on. Try to run a 120V heater on 240V and you may kill it due to the 4x increase in power. If going the other way, from 240V to 120V, the bed/nozzle/etc heating is down by a factor of four.
Most switching power supplies can run off 120V or 240V with no problem. It’s the heaters that trip things up.
