3D printer not working

Hi,

I recently installed nanodlp in a brand new raspberry pi 4, to replace an old raspberry 2 that broke.

With the new raspberry 4 I am not able to project light with the projector.

Do I have to write any code before trying to use the projector?

What steps do you follow once you have a 'brand new' nanodlp to set it up.

Thanks!

It is usually not difficult, if resolution is not detected correctly (tvservice -s on ssh terminal can help you) you should define it on config.txt.

You mean the file on the SD of the raspberry right?

Re: 3D printer not working

I have seen in the config.txt you can delete de # of certain lines to add them to the code.

Maybe trying to delete the one referring to the HDMI?

Right now I have it ''original''-new, what do you recommend to change / add.

Re: 3D printer not working

if the tvservice report wrong resolution, remove all HDMI/framebuffer related ones. If it is not working correctly after removal, add correct resolution manually by using HDMI group and etc.
