Hi!
I can't open the new file, it's giving me an invalid PDF error. All the others are fine.

Edit: it is working now, thank you for fixing it!

Sorry, yep file was corrupted on upload.
Have replaced the file & also added a firmware beta folder.

In there is the latest 4-0-09b firmware.
alignment screen also now allows touch to scroll down the menu as well as pressing the encoder.

Hi!
I have installed the beta version, it is working fine. My blue button is not working on the alignment screen (it does switch the info on the main screen), but touch does.

And I think I found an error in SD-card wiring. At least on my display-pcb pins go like this: CDI SDO SDI SCS. So the wiring will be: blue, yellow, green, white. I repinned my connector (switched green and yellow) and SD card is working now.

Hi,
Thanks for the feedback.
New beta firmware on Github (still the same file name).
Encoder & touch works in the Alignment screen, for progressing the menu selection.

For parameter changing, one still has to turn the blue button/encoder.
Touch parameter functionality will be added shortly.

Will look at the SD card wiring.
