Topic: Solidoodle 3 - Bed won't heat past 85°C
Title says it all. I am using a Solidoodle 3 at work for the first time (I have a 2 at home and have never had this problem). Short of using a heat gun, what can I do to get the bed up to 105°C?

Re: Solidoodle 3 - Bed won't heat past 85°C
I posted this in another topic. I was wondering how other people got their bed to heat up so well also. This is what I had to do. I know there isn't anything besides insulating the bottom of the bed that is a quick fix.
I think the biggest problem that I had was finding out how to get my bed temperature to get past 77-82c. I took a bunch cotton rags and cut them into strips. Then I took Kapton tape and added them as insulation (about 1/2 inch worth) to the bottom of the bed. That brought my temps up to 85-90c. Then I added the glass which helped trap the heat and that got me to 95. The addition of an enclosure made it so I could get 100C.
SD3 w/ mods:
Glass bed with QU-BD heat pad upgrade, threadless ballscrew w/ 8mm smooth rod, spectra line belt replacement, lawsy MK5 extruder, Lawsy replacement carriage, E3D hotend, Ramps 1.4 w/ reprap discount controller, DRV8825 drivers, 12v 30A PS, Acrylic case, Overkill Y-idlers, Filament alarm, Extruder fan + more.

The latest beds from Solidoodle are firmware limited to 87°C.. Unsure as to their reasoning beyond it will limit warping on their alu beds (downside of higher temps on the bed).
Your only choices are raising the ambient, or downloading a newer firmware and it will have the higher bed temp setting.
Unsure what date they made the change, from memory, it was early March so any delivered since then will have the lower temp setting in firmware.

It's not a firmware change, it's a heater change - the current one is lower wattage.

Ah, dang. Yeah, we just got this one in about a month or so ago. Do you have any idea where I could find the newer firmware?

I can understand it being lower wattage lowering its overall performance, but they said its *limited* to 87°C . Even if its a lower wattage, it will just take a longer curve to heat up to 95 etc.. it will get there, just takes longer.
Conversly, SolidoodleSupport have posted its 'limited' to 87° since early March.. I have an SD3 with an Aluminum bed and it heats fine having adjusted the firmware to allow it.. Which is where I'm coming from. But a lower wattage bed wouldn't limit it - just mean it takes forever to get there (No different to me playing with the PID values on my QU-BD).

If this was true then on a long enough timeline a lightbulb would approach the temperature of the sun. 
A lower wattage heater reached thermal equilibrium at a lower temperature.
For a given thermal resistance, delta T is proportional to the heat input to the system.
Furthermore if what you're saying is true, then what 2n2r5 observed cannot be true.

okies, i'll happily admit my ignorance, but that was my interpretation of what they had achieved in 'limiting' to 85°C. I must just have an older bed..
