• Zero configs imported error:
  Make sure you have unzipped the downloaded file before importing.
• I can't find the P1S access code:
  The access code is located on a blue label on the front of the machine.
• I can't connect to the printer:
  The printer is only accessible on the MKROA network. Ask shop captain for login information. You will need to restart the slicer after switching networks.
• I still can't connect to the printer:
  Go to the network and set to “private” rather than “public”, and restart the slicer.
• I still can't connect to the printer:
  If you use a VPN, you may need to turn it off for printer visibility. Some VPNs work fine, others prevent network discovery.
• I still can't connect to the printer:
  Make sure the printer is on, and that nobody else is currently connected.

The machine profile includes configuration files for the printer, as well as print process and material settings.
