Cannot connect to the UV light projector

Hi,

I was using nanodlp for DLP with the raspberry2.
Now I upgraded my raspberry to the 4+, and also upgraded nanodlp.

The Z motors work perfectly but I cannot control de UV projector.

Any experience with it?

Thanks in advance,
Francesc

Re: Cannot connect to the UV light projector

Hi,

I imagine it is a very general problem, not a specific projector problem...
So do you have any idea what problems can cause than the nanodlp and the projector don't connect properly?

Thanks!

Re: Cannot connect to the UV light projector

did you check that the usb node is created or not when it is connected to your pi?
also there are usb2 and usb3 or rpi4, did you check usb2 port which are black?

Re: Cannot connect to the UV light projector

connect to your pi by a software like putty, then list content of the folder: /dev/  , then connect the light engine and then list again the /dev/, something like "ttyUSB0" must be added if not, the usb device is not recognized.

Re: Cannot connect to the UV light projector

Hi,
I do have a lot of tty.... but none of them related with the USB. (I attach a picture of what I obtained.  https://ibecbarcelona-my.sharepoint.com … A?e=MGmxMu )

What can I do to make de raspberry/nanodlp recognize the USB device (projector).

Thanks a lot!
