thanks for the update about compiling. My experiences are that using network drive can slow the compile process significantly and use of SSD HDD can reduce the time 🙂
It is strange that the compile took minutes when reside on local C:\ drive.
I believe that's all you need. Now it's on you to build upon this concept.
Btw, what is your motivation for building your very own HMI? From your questions I guess that using the HMI Designer and building the HMI without any hand coding would be much easier and more straightforward for you.
I tried your proposal, but unfortunately it did not work.
At the end I decided to simply re-image the SD card and start from scratch. Installed the most recent Rexygen test version and now, all is working fine.
Thanks for your support.
