Hi all. I’m currently in the process of building an enclosure that powers the printer, heater, white leds for working on printer and eventually the top section will have UV leds and be used as a curing chamber ... I have it all running from a 30a 12v PSU. I get a weird whine but only in certain situations. If the heater is on a heating cycle and I press pause on the printer, as soon as the heating cycle finishes , it whines. If the heater is off and I turn on the white lights, I get a whine. Would this be coil whine from the PSU or feedback from the printer itself. Thanks in advance. ( and for the people who suggest a heater isn’t needed, mine is in a garage that has repeatedly been in the minus Celsius over the last few months)
大家好. 我目前正在建造一個圍欄, 為印表機, 加熱器, 白色led提供動力, 最終頂部將擁有紫外線led, 並用作治癒室... 我都在30開始運行. 12 v psu. 我得到了奇怪的抱怨, 但只有在某些情況下. 如果加熱器是在加熱迴圈, 我按印表機上暫停, 一旦加熱迴圈結束, 它就會發出呼呼. 如果加熱器關了, 我開啟白色燈, 我就會發牢騷. 這是psu的線圈抱怨還是來自印表機本身的反饋. 提前感謝. (對於那些建議不需要加熱器的人, 我的在一個過去幾個月一直在減去攝氏度的車庫里)
