TH3D Unified Firmware build.

Has anyone built this successfully? I have been at it all day. I have VS Code and all the dependencies installed (gcc, g++, python, etc) on a Linux box. I updated the LCD and it took. Built the firmware several times on every micro SD card I have, all formatted FAT32.

When I put the microSD card in the machine (Ender 3v2) and apply power the screen stays black and the little speaker on the back of the LCD starts screaming. Literally screaming. Had no idea that little sucker could be so loud. TH3D support states this is expected in some printers and to let the firmware do it's thing. I let it scream as long as I could stand it but it didn't take. Any ideas? A quick Google search finds lot's of folks having this issue.

Thanks in advance

Hi what screen are you using on the ender3 v2 is it the stock screen

staticlinerich

Yes. The entire machine is stock except for the EZABL and the Creality Direct Drive I put on it. I did have Jeyers firmware on it but he doesn't have a build for the EZABL. I so desparate I'd even take firmware built for the platform with Direct Drive option enabled. Basically the printer is a paper weight now.

I am sure the th3d firmware doesn't support the stock v2 screen you would have to chande the screen to the ender3 or 3pro screen someone will correct me if I am wrong

That would be a real kick in the testicles if that's the case. That's not in any of the documentation.

I maybe wrong someone will correct if I am, I remember watching I video about changing the screen a while back and I am sure it was the v2, this may of changed, now you have got me thinking, it maybe the ezboard with the stock v2 screen

From the TH3D Ender 3v2 Unified Firmware page:

"Creality Ender 3 V2 – Babystepping is accessible with Unified V2.31 and higher through the Z-Offset menu item. Swapping it to the 12864 LCD will give you many other features. See our guide on changing out the LCD to get more features."

Getting more features is cool, but I just want to print with my shiny new EZABL. It doesn't say you have to upgrade the screen. Shoot, at this point, this Anycubic Vyper is printing circles around the Ender 3.
