Yes, those instructions should work. Just be aware that you must update the firmware to use the new web interface. A guide on how to flash the firmware can be found here: [
reprappro.com] You can use either dc42's firmware or my latest one here, just click on "Raw" to download it: [
github.com]
You may want to wait for my next firmware and web interface versions though - I basically have both of them ready, but I'm still waiting for feedback to verify that it resolves connectivity problems some users have been experiencing.
