CHAPTER 1. GET CONNECTED TO THE POLAR CLOUD 24

add your 3D printer’s MAC address to the li s t of hardware on the

network – similarly to how they would add a laser printer.

Make a note of the MAC address of your printer, as your

network administrator will likely need it! The MAC address is

printed on the backside of the “GETTING STARTED”sheetshipped

with your Polar3D printer. The MAC address may also be found

displayed by the printer local web interface: after connecting to

192.168.0.1,lookundertheheader“Network Information”

for the value in t h e “Current MAC” ﬁ el d ; see for instance Figure

1.8.(Indeed,theprinterlocalwebinterfaceshowstheMAC

address in multiple places; see also for example Figure 1.20 or

Figure 1.21.)

Note that if you have left your Polar3D print er conﬁgured to

potentially use multiple WiFi networks, then the MAC address

displayed may di↵er in its ﬁnal digit from the value printed on

the “GETTING STARTED”sheet.

1.3.3 Open HTTP ports

Outgoing HTTP ports 80 and 443 must be open to t h e printer.

If your local network does not allow the print er to access those

outgoing ports, then the printer’s attempts to connect to the

Polar Cloud will not fully succeed.

In terms of LED lights, the symp t om you will see when the

rest of conﬁguration was successful but now the printer can’t

access the outgoing HTTP ports is that the LED li g hts will be

blue over yellow: POLAR3D .

Make a note of your printer’s IP address (if you are using a
