@dc42 I tryed other power supply today the same one 24v 15a 360w, and when heating it the bed,in the new power supply is burned to 160ohm resistance... I so strange because the first one don't have nothing burned and work fine just the sound...i buy a new hotend for extruder a new hotbed, tomorrow i try the extruder, the bed is take more time to come, but a say anything here when i change it. Thanks for their help.

@phaedrux yes i got a little less than 300w, i have free 50w or more

@phaedrux i think the bed i not sure but i think is 220w and the hotend is 50w, is fine? i think i have more i need.

@phaedrux that one is a good choice? Meanwell lrs 350 24v 14.6a 350w

@phaedrux i tryed 3 different ones, i don't think problem is of power supply. But thanks for the idea.

@phaedrux one is Creality 3D DC 24V 15A 360W, the other two are Chinese from amazon NEWSTYLE DC 24V 15A 360W

@phaedrux yes the sound is made by the power supply when the bed mosfet or the hotend cuts and opens, I have tried 3 different power supplies and the sound does it with all 3.

@phaedrux So update ok, reinstall by bossa and upload the files to the sd. Really everything works well, it is only when heating the bed or the hotend the power supply beeps as I showed in the videos, I already tried to change everything, I even tried 2 sources and the problem continues, I only have to try another plate ... I don't know what can be failing, change cables, thermistor, hotend, complete bed, 3 different power supplies and keep beeping when it reaches the indicated temperature.

@phaedrux If I have access via web and usb that is not the problem, the question is if I erase the board and install 3.2.2, that version has all the necessary files or should I first update to 3 and then 3.1 ... to 3.2.2

@phaedrux I think that when I updated my motherboard I made a mistake and some version did not install well. I want to do a clean installation by deleting everything with bossa and installing the board from 0, the thing is which is the best version to install and update, or do I directly load the 3.2.2 again?

@phaedrux yes i have 3.2.2 now but i want reinstall and new update, what is the best software to start ne install from 0... 2.00 or 1.21,or 3??i think maybe i don't install one file from old updates.
