I am currently using the Ender 3 Pro with 4.2.7 as well as a V2 color screen that I bought with the 4.2.7 mother board off of amazon. I do not see an option to enable the V2 screen when going through the custom firmware builder.
For the DWIN based screen, you’d need to pick the Ender 3 V2 and build from there.
I believe the rest of the physical hardware configs are the same.
Thanks, I am trying this now but receiving the following error from the build.
I loaded up the v2 firmware with bltouch and that seems to work on the ender 3 pro. After doing bed leveling and z-offset stuff I needed to preheat the nozzle so I did that for PLA, and then eventually got an error saying the temperature was too low. Any ideas? It’s a relatively new printer only has about 10 hours or so on it.
Likely you need to perform a PID Tune. It’s also a good idea to make sure the silicon sock is fitted correctly to the heat block.
Bryan has a guide here: PID AutoTune your Ender-3 V2 (or other Marlin-based 3D Printer!) - YouTube
I went back to the original screen and bltouch forward and everything is working just fine, so would v2 firmware cause this, and just doing PID auto tune should resolve?
I’m not 100% sure - as the thermistor reading would be the real key.
If it reads too low, Marlin doesn’t know if its disconnected or not - so there’s a minimum temperature that is a cutoff as ‘maybe broken thermistor’… We see this more often in places with cold climates where people keep the printer in the garage or shed…
It’s certainly worth a try though if you want to keep using the Ender 3 V2 screen - however at the moment, the text based screen is much more functional.
That is until this work is finalised and merged: https://github.com/MarlinFirmware/Marlin/pull/21942
