Topic: Bed Time
How long does it take your bed to heat? I'm seeing 11 minutes to go from 19c to 90c. Someone mentioned printing with a bed temp of 110, and I don't think I could ever get there, short of moving to a warmer room.

Re: Bed Time
I keep the room my printer is in at around 72F. It takes my bed about 10 to 12 minutes to reach 110.
Printing since 2009 and still love it!

Re: Bed Time
That's about what it takes for me as well.
Re: Bed Time
me too.
Re: Bed Time
Sounds like my bed is half dead then (for 100c it took 18 minutes). I filed a support request. Thanks.

Pick up a cheap IR thermometer and measure it in various spots. I visually separate mine into 9 sections and measure each section. That's how I know the middle is 10 degrees hotter than the edges.

Re: Bed Time
My bed no longer heats to 100c, so I can't print. I know you'll be shocked to hear that there's been no reply to my SD support request 10 days ago.
Re: Bed Time
Anyone know the proper resistance for the heat bed (unplugged from the board)?
Or the normal supply voltage for it?

Depends on the machine. Normal is 12 or 24 volts. Usually it is 12 for most machines.

Re: Bed Time
I was specifically thinking of the Press, this being the Press forum and all. I see the heat bed is stamped "24V 90W". I don't know what temperature they measure 90W at. Assuming they use metal as the heating element, you'll see the highest power at the lowest temperature, so the wattage is probably specified at room temp.
Anyhow, 90W @ 24V works out to 6.4 ohms.
Re: Bed Time
SD sent me a new heat pad for the bed, and I can again get to 100C (13 minutes from 22C).
In retrospect, I think the old pad was not well bonded to the bed, because it came off very easily.
(5 1/2 weeks support turn around time on that.)
Re: Bed Time
13 minutes to go from 20C to 100C for me.
Re: Bed Time
I had the same slow temp rise, couldn't get to 100C.
Looked underneath and the heater was coming loose from the bed, rubbed it back on.
Wrapped a piece of 1/2" fiberglass acoustic ceiling tile in al foil, stuffed it under the bed for thermal insulation.
Now I can hit 105, and 100 cycles nicely.
Check under the bed....scary stuff!
Re: Bed Time
No monsters under my bed - they'd get squished when the bed tries to return to China during homing.
Mine wasn't visibly loose, but it peeled off too easily and mostly cleanly. Perhaps the bed wasn't properly cleaned before the pad was installed.
I have some ceramic wool to try under it. I hesitated on a using ceiling tile because I wasn't sure if the binder would slowly char. Did you need to tweak the heater feedback settings?

Same here. It took more than a month from when I reported it (with photos of the damage in my case) before I got the replacement. The temp sensor is in the pad itself, so even if it wasn't well attached it to the bed, the pad should have been able to reach/read 100c or more.
Glad to hear it's working.

...assuming it was evenly adhered. If the area with the sensor had good thermal contact, but not the parts around it, it would cause that problem. Anyhow, I'm back to printing again.
