Can't connect Well this is perplexing, and frustrating. I can no longer connect to the Printer via the computer. When I try to connect either via Printrun or via Arudino environment I get an error. Printrun yields the following error. [ERROR] Could not connect to /dev/tty.usbserial-A60221BU at baudrate 250000:\ Serial error: could not open port /dev/tty.usbserial-A60221BU: [Errno 2] No such file or directory: '/dev/tty.usbserial-A60221BU'} I have tried turning the printer off and then rebooting. I have tried replacing the USB cord. Neither had any effect. This happened yesterday, and rebooting the printer corrected the problem, but now nothing works, can't connect. The printer is getting power, (i.e. fan comes on) (And just as I was starting to get quality prints)/ What should I try to diagnose this problem? For what its' worth I am on a Mac not a Windows machine. https://reprap.org/forum/read.php?292,302181,302181#msg-302181 Sat, 18 Jul 2026 19:53:04 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?292,302181,308798#msg-308798 Re: Can't connect https://reprap.org/forum/read.php?292,302181,308798#msg-308798 TheTechnicalNoob Mendel90 Mon, 10 Feb 2014 02:14:54 -0500 https://reprap.org/forum/read.php?292,302181,302358#msg-302358 Re: Can't connect https://reprap.org/forum/read.php?292,302181,302358#msg-302358 academicdave Mendel90 Tue, 28 Jan 2014 08:02:29 -0500 https://reprap.org/forum/read.php?292,302181,302300#msg-302300 Re: Can't connect https://reprap.org/forum/read.php?292,302181,302300#msg-302300 nophead Mendel90 Tue, 28 Jan 2014 05:55:08 -0500 https://reprap.org/forum/read.php?292,302181,302181#msg-302181 Can't connect https://reprap.org/forum/read.php?292,302181,302181#msg-302181
