Build 1529 missing /dev/ttyACM0
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

Maybe cable is lose or something as nanodlp update could not make USB device disappear. Also it could not change from ttyACM to ttyAMA as these names refer to different type of devices.

Re: Build 1529 missing /dev/ttyACM0
If I remember correctly nextion is using serial connection, disconnect nextion and see if it makes any difference.
I doubt it is related to nanodlp as error indicate missing tty file, which could be linux setting or hardware issue.

SSH and Run command below on RPi.

Paste the result here.

Put space between -I and /dev

Re: Build 1529 missing /dev/ttyACM0
Base on shared screenshot I believe you have extra space after slash on serial port address. (setup page)

Re: Build 1529 missing /dev/ttyACM0
I had noticed that error and changed it, but from the NanoDLP setup set the space, how can I fix it?
I removed the space 5 times and finally memorized it, although the setup page remains the space now works
