CNC milling from Anet a8+ frame, btt skr mini e3 V3, ender 3 v1 screen, and marlin firmware. what can possibly go wrong ?

Posted by Scaleo 
Hello everyone,

Since i had a new printer, I'm converting my a8 with metalic frame into a CNC milling machine.

I manage to build marlin bugfix in my old Anet a8 board but now i'm trying to build one in a btt skr mini but it failed every time.

I'm able to flash it, since the file firmware.bin is renamed into .cur in the sd card. But unfortunatly, my ender 3 v1 clone screen is powerded but still blank at each try.

I defined it as cr10_stockdisplay and use the special ribbon from the btt board kit, but can't get anything showing in the screen . When i try to define the reprap one, i got an error telling me that it's not supported by my btt board. I even tried with the Anet screen, the zonestar but it also failed : powerded but nothing showing on screen

as I'm in debbug mode, i juste have my board and screen on my desk, no sensor nor stepper motor plugged in . I take my 12v power from a lipo pack .

I tried a fresh config.h, the one from the dedicated template for ender 3 , marlin 2.5 and marlin bugfix but i can't get a boot, or a least an image/text on the screen ... Even without spindle-feature enabled in config_adv.h

Also, in the ender 3 config sample folder, they are 2 files i don't know what to do with : _bootscreen.h and _statusscreen.h.

It's driving me crazy because I'm sure it's an obvious thing i missed. Please help me.

Also, I'm french so my english may be approximative.

Thanks in advance.
