3D turns and stays yellow?
Modified on: Wed, 28 Mar, 2018 at 4:12 PM
Your Polar 3D printer's logo doubles as an indicator light, telling you what state the printer is in.
If your printer boots up and the 3D is Yellow, you're connected to the internet but not talking to cloud.polar3d.com. Your network has blocked internal systems from going out to the internet and thus need to allow the printer. The printer itself uses HTTP and HTTPS.
Everyone's situation and setup is different, so please work with your network administrator to allow the printer to talk to the cloud. This could be by doing one of the following:
"Whitelist" the printer's MAC address, found on the Getting Started guide, or in the printer's Local UI
Unblocking outgoing ports 80 and 443
Your "Getting Started Guide" comes with the printer's eLAN and wLAN MAC addresses listed. Please forward both to your Network Admin staff so they can allow outgoing connections to Amazon S3.
Sites that need to be accessed by the printers:
For Polar Printers: printer2.polar3d.com, asset.polar3d.com. TCP ports 80 and 443.
For Flashforge Printers: printer2.polar3d.com, TCP ports 80 and 443.
NOTE FOR NETWORK ADMINISTRATORS:
The DNS A records for these domain names can and do change regularly. They are behind load balancers and Amazon AWS does every so often change the DNS A records for them. Moreover, those load balancers are multi-homed and thus can and do have multiple A records. And they additionally reach out to Amazon S3: they perform HTTP/HTTPS GET requests against Amazon S3 sites. The FF printers with cameras also perform HTTP/HTTPS POSTs against Amazon S3 sites (uploading camera images). There is no one host name for all HTTP/HTTPS GET and POSTS other than to allow *.amazonaws.com. (The S3 region can change; it dictates whether it is s3.amazonaws.com or s3us-east-1.amazonaws.com or s3us-west-2.amazonaws.com etc.)
