Looks like a 10ohm resistor (brown -black-black - correct me if I'm wrong as the photo is a little dark and I'm colour blind) which will take 260C down to just under 233C. I think the PLA temp is 190C (folks please chime in to correct) which will mean just under 164 degrees C.

Does that help?

There's an interesting post by "Robin" here:

I've not checked myself, but if true it may be that UP are not able to provide temperature control.

Has anyone tried putting a 25 ohm pot in series with the sensor and calibration their own temperature profile?
Or maybe a 12 position switch with 1.8 ohm resistors at each tap? That should give about 5 degree steps.

I very much doubt it would be a hardware controlled setting. For a few reasons.

1. They were able to add in PLA support in the firmware.
2. If there was any changes in the filament formula they would be unable to tweak it.
3. If there was any hardware changes they would be unable to tweak the PID loop.

I can however confirm that the UP mini is a hardware thermostat for bed temperature so that cannot be tweaked. Well unless someone decides to swap out the part for one with a higher setting.

So the real question is where do they send/store that value for the temperature.

I did a bit of investigation a while ago to try and pull out the USB data when picking a new roll. And I think PLA vs ABS is different but so much data to sift through its hard to tell. I would have to write some code to scan through it and actually tell me anything meaningful and free USB pass through tools are bit limiting for the moment.

What would also be interesting is to see the raw contents of the SD card. As we all know the UP has the functionality to just "print again" so we should be able to see the structure of the code for the latest model and if it was me I would put the roll usage and type on there maybe also some settings.

Anyone know who sell this switch in europe? Or someone send it from Usa?

This has all been gone over extensively on this forum in the past. I can't find my original post of nearly a year ago where I published the Up's reported temperature versus thermocouple resistance, but the spreadsheet is attached hereto. The thread:

http://www.pp3dp.com/forum/viewtopic.php?f=3&t=1058

shows how forum members built on that data to make practical temperature control mods.
