Topic: partial bed heating

Today I noticed the print bed temp would not go any higher than 78c , even tho I have it set to 95c in RH printer settings. It took hours even to get to that temp.Bad heater or board?

Re: partial bed heating

has it ever reached 95 for you?

do you have the stock power supply unit?

Stock PSU and heater tends to be limited between 78-86 ish degrees, before the power supply and voltage limits it. I have a slightly higher wattage PSU at a higher voltage (~13.7v) so it pulls more current (bc of higher voltage) and the unit can deliver it. But even then my stock heater is limited to about 95C

Re: partial bed heating

Will this work with SD3 stock PS? It says it draws up to 15amps http://store.qu-bd.com/product.php?id_product=61

Re: partial bed heating

Check the for sale section in the forums. Someone was giving away a sd3 platform. You could just replace the heater then.

QU-BD silicone beds have been covered plenty here if you search and no, the stock power supply is not up to it.

Re: partial bed heating

I have 300 watt atx psu , says 12v and max current of 15A. Specs are good, just wondering if I could replace the stock SD PS with that.
