okay, so now that the hotends are functional, is anyone having trouble getting there bed to heat up past 95? Mine never goes passed that..
Okay his is how I fixed the heated bed not being able to heat over 95, just a large layer of paper towels under the bed.
Sounds like there is a current problem. Doesn't seem like you have enough wattage coming out of the Power Supply.
I dunno just seems like it's too cold in my house and can't quite get hat extra few degrees... Its18C, or 65 degrees..
I was heating my bed to 120C no problem in a 10C room. Do you have the heatsink connected to it Go ahead and measure the resistance of the heater and the thermistor for the bed. Then the voltage output like we did before. then see if maybe the cork is drooping in the middle, or maybe the thermistor came a little loose by pressing in the middle
HAHAHAHAhahahaha....... Lol I'll check it, the cork isn't drooping, it secure. I'll post what I find out.
Hmm i've checked all three, Will do again 8.9 ohms at 51C approx (This time I pulled of the cover and measured where it plugs into the board, disconnected the wires first, Last time I unplugged the bed and tried to measure the plug connectors. and .6ohms is what my multimeter internal is lol) 34.9kohms for thermistor
Oh this is also interesting, I checked the actual bed temp with my FLIR, and at 95C bigbox reading, the top of the bed was only 65C, and it had been on for like 2 hours
Take the glass off if you're going to try that. Let it cool down and measure the resistance. Keep the bed plugged in, and measure from the Bed Out on the rumba I just verified on mine it's around 2.7ohms Something is not properly plugged in somewhere, maybe a wire is loose, but you should be seeing exactly the same thing
Okay, so earlier when i was getting .6ohms when measuring the connector on the heated bed, I was doing red to red, dumb. I am still getting 8.6ohms directly on the connector, for both pairs, so it isn't the wire...
I took out the mechanical splice on the wires, where it splits off into two wires for the bed connector and soldered them together, and now each leg is at .9ohms, still doesn't heat up
Ok I'm a little concerned with what you're doing. Please post a picture of where you're taking these measurements. I can't really commit to anything since I'm in the middle of selling my house
