nanoDLP

Hello!

I have an Rasperry Pi 3 and an Wanhao D7 printer.

I "etched" the last image of NanoDLP on a SD card, no error message when starting. But then I clicked on "update" and after that, I got an error message. Now it says build 1529 and the following error message:

"ActionSerial port could not be activated open /dev/ttyACM0: no such file or directory"

When I check with I only find another driver:

pi@raspberrypi:~ $ ls -l /dev/ttyA*
crw-rw---- 1 root dialout 204, 64 Jul 30 14:48 /dev/ttyAMA0

What to do?

best regards,
Jeniara
