Another board for w600
http://arduino.w600.fun/package_w600_index.json
Also i save https://www.costycnc.it/arduino/w600-arduino-0.2.6.zip and https://www.costycnc.it/arduino/wmtools-0.3.2.zip and insert in C:\Users\yourpc\AppData\Local\Arduino15\packages but idont know how make working this
also i see that if I succeed to install package ... give me a little error ... but after install
when install check set environment variables
... the error when compiled dissapear but give error when need to upload code to w600
So ... for now i use tool.exe from https://github.com/vshymanskyy/w600tool/releases/tag/0.1 to upload code to w600
Check in arduino "Show verbose output during x compile and will see the location of img file
In folder upload from above i create a batch file for windows as example
Here WM_W60X_Firmware Generation Guide V1.2 https://www.winnermicro.com/en/upload/1/editor/1559640549130.pdf
