Getting your printer ready
Already have access?
If you already have access to Mainsail, Fluidd or Moonraker, you can skip this step and continue to the next step.
Important: Makerbase mainboard warning
Neptune 4, Qidi Tech & other Makerbase-powered printers
If you have a Neptune 4 Series, Qidi Tech printer, or another printer with a Makerbase mainboard, your Moonraker version is likely outdated and cannot be easily updated.
We have dedicated setup guides for these printers:
Elegoo Neptune 4 Qidi Tech Comgrow T300 Other Makerbase printers
If your Makerbase-powered printer is not listed but you can access Mainsail or Fluidd, try continuing with this guide first - the regular setup may still work.
Checklist: Accessing your printer's web interface
Follow these steps to access Mainsail or Fluidd on your printer:
1. Enable WiFi or Ethernet
Make sure your printer is connected to your network.
- WiFi is usually enabled via the screen on your printer
- Alternatively, plug in an ethernet cable to your printer and router
2. Find your printer's IP address
You need to know where your printer is on your network.
- The IP address usually shows on your printer's screen or in its settings
- Can't find it? Check your router settings for connected devices
- Or use a network scanner tool like Angry IP Scanner
3. Access Mainsail or Fluidd
Open your printer's web interface in a browser.
- Make sure you're on the same network as your printer
- In your browser, type the IP address:
http://192.168.1.100(example) - Or try:
http://mainsail.localorhttp://fluidd.local
Moonraker too old? SSH fallback available
If you discover in the next step that your Moonraker version is too old (older than v0.8.0) and you can't update it through the web interface, but you do have SSH access to your printer, you can use our SSH setup script as a fallback. This script works on any Klipper printer with SSH access, not just Makerbase-powered ones.
Ready to proceed?
Once you have access to your printer's web interface (Mainsail, Fluidd, or Moonraker via SSH), continue to the next step where we'll enable SimplyPrint!
Thousands complete this setup every week. Follow each step carefully - most issues come from skipping ahead.
That's it! You're all set
You're now ready to connect your printer and start using SimplyPrint.
