Can anyone help with getting my Aurora 3D printer to work on my Mac? I just finished assembling my Aurora 3D printer, I downloaded the repeater-host software on my mac, but there is no communication between the 3D printer and the repeater-host software. When I press the button to connect I get two messages: -Attempting to connect to printer -Couldn't open port for device None What am I doing wrong? How do I open the port to this device? Am I missing a step? How do I go forward? https://reprap.org/forum/read.php?406,608177,608177#msg-608177 Mon, 13 Jul 2026 17:58:41 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?406,608177,608306#msg-608306 https://reprap.org/forum/read.php?406,608177,608306#msg-608306
1) Make sure the baud rate is the same of that in your firmware.
2)Make sure your computer recognizes the printer.

Both of these options are under the config menu in the host. To change baud rate use the drop down menu. To identify the printer port click "refresh ports" without the printer plugged in. Take note of ports avalible. Then plug in the printer and refresh again. That is the port of the printer.

See Arduino.cc if you cannot see the port.

Personally I would recommend using a Raspberry Pi and Octoprint or the even cheaper 12864 style lcd.]]> gmckee Prusa i3 and variants Mon, 11 Jan 2016 17:58:06 -0500 https://reprap.org/forum/read.php?406,608177,608177#msg-608177 https://reprap.org/forum/read.php?406,608177,608177#msg-608177
