Cartouche de chauffe

Maybe - the existing resistor bore hole on mine was 5mm. Your listing is 5.5.

I hand reamed it using a 6mm drill bit (the cartridge I used was 6mm)  that I inserted in a drill press and turned by hand to slightly ream the hole. I didn't need power to the drill - the heater block is very very soft.

You can not replace the insulation once installed - the cartridge extends beyond the heater block. So you will need some cotton insulation wrap, or lots of Kapton.

Hmm, I'm not familiar with the SD2 power supply.
The cartridge at 100% will need 3.3 Amps. The existing Resistor uses 2.5 Amps - so it needs 800ma more. This might be ok on your power supply.

You can limit the cartridge to only be able to run at 80%, which will slightly slow down heatup time, but will mean it only draws 2.5Amps. This is a setting in firmware.

I have long since upgraded my heated bed, so have a much more powerful power supply anyway.

Someone with an SD2 can perhaps confirm what the existing power supply is capable of - it might be able to take the extra 800ma just fine (thats not big in the scheme of things....)

Oui elle marche tres bien sur la SD
C est ce que j ai mis (du meme fournisseur)et ca marche et c est une qualité meilleure que celle d origine. !!!!
LE seul ennui c est que le diametre du corps de chauffe est plus petit....
Moi j y ai mis un bloqueur dedans.....
