    I made myself a Christmas gift and bought a 12V E3D-v6 bowden to replace the stock extruder on my Wanhao Duplicator i3 V2.

    I followed the guide here to set things up: http://wiki.e3d-online.com/wiki/E3D-v6_Assembly

    At some point I came to the Heater Cardridge section: http://wiki.e3d-online.com/wiki/E3D-v6_Assembly#Heater_Cartridge

    It says to check the resistance of the stock heater cartridge and compare it with the E3D v6 heater cartridge. I got 4.6Ω from the stock cartridge and 5.6Ω from the E3D cartridge. So, following the cartridge table in the guide, I should have a 30W cartridge mounted on the printer, and the v6 should have a 25W cartridge. However, the guide says that a difference around ±5W is fine, so I think it should be fine to use the cartridge from E3D. Is that really fine? Also, shouldn't the 30W one be able to produce more heat than the 25W one? If so, should I stick with the stock one?

    Then I came to the Configure Firmware section: http://wiki.e3d-online.com/wiki/E3D-v6_Assembly#Configure_Firmware_.28Easy.21.29

    It says I need to edit the firmware configuration in order to use the Semitec 104GT2 thermistor. I can't seem to find the i3 firmware from Wanhao: all I got was the firmware in HEX format, and it's really useless.

    Probably Wanhao didn't release the firmware source code, so I think I'll not be able to edit it to configure the new thermistor. Can I use the stock thermistor instead?

    Thank you

    The +/-5w means a deviation from the expected value for the E3D hotend. E3D hotends ship with 30w heaters. Assuming the physical dimensions are identical, you can use either heater in this application.

    You can use the stock firmware if you use the stock thermistor, and you can use the stock thermistor if you get an "old style" heater block from your supplier. I know we have these at Filastruder, I'm not sure where you purchased from.

    Hi, thank you for your answer.

    How do I tell if I have an "old style" heater block?

    I purchased from the E3D website, and placed the order on december 25, so I should have got the latest version (I think). The one with the long cylindrical thermistor instead of the glass ball

    Edit: I think I have the answer myself. I just checked the heater block on my i3 and it has the ball-style thermistor, it doesn't have the cylindrical version as the v6. So what should I do if I can't change the firmware?
