Monoprice Select Mini V1 Not Detected

AstroBox Troubleshooting
#1

I have a Monoprice Select Mini (original version.) The startup screen reports V22.39. I have tried installing Astrobox 0.10(8) on my raspberry Pi B+ several times, but my printer is never detected (AstroBox thinks there’s no printer plugged in.) The printer worked fine with OctoPrint on this same Pi. When I SSH into AstroBox, I can see the printer with lsusb. Here’s the output of lsusb and dmesg:

Does anybody have any ideas? Thanks.

Did you try changing the drive to the S3G in settings -> Printer Profile? I don’t remember if that printer has Sailfish firmware.

#3

I tried this after getting your reply, but it still wasn’t detected.

#4

I tried manually adding the serial port and baud rate to /etc/astroprint/config.yaml and Astrobox now shows that it is connected and printing appears to be working. I am printing something right now and everything is fine so far. Under the connection settings, it shows ‘Connected to printer’ but still shows ‘No printer detected’ under ‘USB device.’

#5

What did you put on the config file?

#6

The serial line originally read:

 serial: {}

I changed it to the following:

 serial: 
      port: /dev/ttyACM0 
      baud: 115200

I think I got the idea from this ticket on GitHub: https://github.com/AstroPrint/AstroBox/issues/281
