Build targeting mks_robin_nano35_v2 does not work

[mgcrea]

I received an MKS Robin Nano V2.0 from AliExpress that I had to reflash to configure a delta printer (FLSUN Q5).

Did reflash with the latest Mks_Nano35_V2.0.3.3 Release file.rar

Unfortunately the printer does not work anymore as I have a blank white screen after boot (see makerbase-mks/MKS-Robin-Nano-V1.X#50).

So I did successfully compile this code with env=mks_robin_nano35_v2 and flashed using the generated build in .pio/build, but I now have a black screen!

Any idea what I could be missing? Could you please give me a working factory build?

Thanks!

1. Follow the steps in the photos.
2. compiled firmaware robin_nano35.bin is in the directory .pio / build / mks_robin_nano35_v2 (warning: the file you're looking for Is Robin_nano35.bin not firmware.bin)

Thanks, it does start OK,

Unfortunately I have trouble configuring the AutoLevel on an FLSun Q5, basically applied these Marlin configuration patches but the printer probes a single point and stops.

Also it looks like the serial communication somehow hangs (can't send GCODE).

Looks like I have put a bit too much hope in this new V2 board as it does not seem to be ready for prime time yet!

Thanks for the help anyway.

you are absolutely right, I too, like you, was expecting something else and instead I find myself with an absolutely immature card without documents ...

Yep I'm a bit disappointed by the UI so far as it feels like a regression migrating from the V1 (except bigger screen). But I guess it will be better with time.

Anyway good news, finally successfully calibrated my delta through the USB serial connection (basically G33 followed by M665 HXXX.XX to adjust Z offset) and I got a great test print from it with dimensions way more accurate than with the legacy firmware that came with the printer.

So pretty happy finally!

Did anyone manage it, to get the Robin Nano V2 to work with the included display in the old 80s style?

Hi mgcrea

V2.0 still under developing using Marlin features
old mks robin (V1.2) compiled under marlin 1.0 and using a proprietary compilator
Now we are under testing new features and merging it into original marlin repository
but, every menu, every button, every function need to be converted do LVGL, tested, before marlin bugfix commits
you can follow discussion in these PR
MarlinFirmware/Marlin#18500
MarlinFirmware/Marlin#18784

Classic marlin display will be added as soon as possible, cause V2.0 share same port to use SPI, FSMC protocol
some changes need to be implemented

1.2V FSMC
2.0V SPI

thats change all the way marlin interpreted this
1.2v is more intuitive, but closed firmware is hard to maintain and marlin inside it is too old
