Why is my UltiMaker printer offline?

Beta: This integration is experimental with limited support.

Quick reference

Quick fixes

First: Try restarting the integration service.

sudo systemctl restart simplyprint-ultimaker

1. Is the integration running?

systemctl status simplyprint-ultimaker

To restart:

sudo systemctl restart simplyprint-ultimaker

2. Check setup

1. Find installation folder (usually ~/simplyprint-ultimaker)
2. Check config file has correct printer details
3. Re-run setup if needed: ./install.sh

3. Network check

ping <printer-ip>

Also check if you can access the printer's web interface at http://<printer-ip>.

4. UltiMaker Digital Factory

If your printer uses Digital Factory:

• Make sure your account is still linked
• Re-authenticate if needed

Alternative: OctoPrint

If this integration isn't working reliably, connect through OctoPrint instead:
