So I loaded the sketch (https://github.com/freerange/printer/blob/master/printer.ino) again (already changed to the Ethernet Shield's MAC address when taught in step 2 of the tutorial)
When finished uploading the printer sketch,the 3 LED flashed for one second only, more than 20 seconds later,the red LED flashed 3 time then kept lighting all the way. what did I do wrong??
Any other information I can provide to help to solve the problem? Thanks in advance
Hello Lauren, I had exactly the same issue when setting up my printer for the first time yesterday. I first had it connected to the router via ethertnet, which had the red LED on constant, then I connected to may Mac via ethernet and turned on Internet and web sharing. This didn't work so I connected USB as well as Ethernet and reuploaded the Sketch - and Bam this worked.

Hi, you just need to uncomment the debug line in the arduino sketch.

Hi James,
Sorry, I don't quite understand how to have the DEBUG flag on when uploading the sketch, I saw this term in previous threads,tried googling it and searching Arduino official site, but got nothing.
Please tell me how to enable it.
thanks!

Hello Lauren, I had exactly the same issue when setting up my printer for the first time yesterday. I first had it connected to the router via ethertnet, which had the red LED on constant, then I connected to may Mac via ethernet and turned on Internet and web sharing. This didn't work so I connected USB as well as Ethernet and reuploaded the Sketch - and Bam this worked.
But then it stopped working, I traced this down to the USB and ethernet both needing to be connected. I'm not sure why it needs the USB cable connected as well as Ethernet. If I disconnect the USB and do not click reset the yellow led flashes as normal until data is sent and the yellow lights up constantly but it never prints.
Maybe try with a USB cable connecting the Arduino and your computer.
My setup:
- Arduino UNO + Ethernet shield
- Adafruit thermal printer
- All components from Oomlout
- Power supply from google (link from components lit)
- 4GB micro SD (formatted to FAT 32)

Hi there,
Found the freerange printer project, thought it was interesting and shouldn't be that hard to DIY, bought everything I needed and followed the "Making your own printer" tutorial step by step.
(FYI I have very little knowledge about electron and programming. ^^;; )
After everything was done,I tried to connected the printer backend server, well,"Sorry, I haven't seen any printers connect from near you."
So I loaded the sketch (https://github.com/freerange/printer/blob/master/printer.ino) again (already changed to the Ethernet Shield's MAC address when taught in step 2 of the tutorial)
When finished uploading the printer sketch,the 3 LED flashed for one second only, more than 20 seconds later,the red LED flashed 3 time then kept lighting all the way. what did I do wrong??
Any other information I can provide to help to solve the problem? Thanks in advance
