Re: touch screen error

Could you let me know which build was correct and now which build you are using?

After updating from 2335 to 2615 it is.
However, in my expectation, after the release of Pi 4, the tibus version does not seem to work properly from the updated version.

Re: touch screen error

Not sure about tibus. But internal one should work correctly.

It works normally when it is set as the default image on the nanoDLP download page.
But after this update, it will be like the video.
Something seems to have changed with this update.

Even in the latest beta version 2645, the touch screen is still flickering.

Re: touch screen error

Not sure what causing this, could you measure how much time between two flicker?

I'll take a video and measure the time.

Best regards Shahin.

version 2335 2s
          2692 1.5s

There seems to be a communication-related change.


I did some tests on version 2962.

1.Pi config = bluetooth stop

tibus touch = normal

Official touch = not working = flickering when printing like video



2. Pie Configure = Use Bluetooth

tibus touch = not working

Official Touch = Normal

Re: touch screen error

You mean when bluetooth is enabled, the flicker goes away?
