Connection Problems from Astrobox to Prusa i3 MK3


#1

Hello, I need help. The connection to the printer is not established. There is no error message but the spinner is running “connecting”, what can I do?

The following configuration:

  • Raspberry Zero W (External power supply, USB to printer, connection via Wifi to router)
  • Prusa i3 MK3 (Current firmware, via USB to RPI)

What did I do?

  1. astroprint flashed on SD card
  2. Raspberry started and connected to the Wlan
  3. configuration of Astrobox executed via web browser
  4. in the web interface the connection tries to establish with baud rate 15200 and 25000. Neither is possible. The connection is established, the loading spinner is running but nothing happens, no error message either.

I have no idea what to do now. Please help me, thanks.

About speed, in firmware prusa has hardcoded value 115200. Today evening I will try to connect my pi zero with prusa, for now I have it conected to other printer and it is working without problem.

For others, I changed my update channel to beta and updated to:

AstroBox_Touch - v0.14(0)
v0.6.0 - AstroBox Touch UI

and the connection to the printer is now established!

Hmm, just checked my Prusa MK3 and Pi zero W is connecting almost without problem, almost because connecting procedure ending up with rebooting the printer… Of course I tried it during the print :stuck_out_tongue: but after that astroprint is connected and I can move the axis and everything. My firmware version is stock 0.13(16). Maybe check the cable?
