Printer won't connect! sad smiley [FIXED]
March 30, 2013 10:01AM
So last night I finished putting together my portabee.
I could connect to the printer fine and move all axes in pronterface, so I printed my very first test object, a 1cm^3 cube with 25% infill. This came out fine.
I then retired for the night with plans to print out a whole load of objects today.
This morning I plugged in the printer and now pronterface can't connect to it
In pronterface's log file it says:

serial.serialutil.SerialException: could not open port COM22: [Error 2] The system cannot find the file specified.


It also does not show up in device manager.
I've tried restarting the computer, and using a different usb cable.
One thing I notice though, is that the LED labelled LED1 on the board, is now constantly on, which I don't remember it being on before. LED2 has always been on and I think that is just a power indicator.
Does LED1 being constantly lit indicate a fault?
I'm hoping the board isn't broken sad smiley sad smiley

Try this.

1. Unplug usb and power, kill pronterface if its running.
2. Plug in power.
3. Plug in Usb
4. Start pronterface and hit connect.


If you leave the usb pluged in when you power cycle the printer it doesnt want to connect, atleast mine doesn't. I think it has something to do with the board getting power from the usb and not completely restarting when you just restart the power supply. I realized this when my fan would continue running even tho my power supply was unplugged. lol

I have a printrboard rev D

Have u tried seeing if it will show up on your computer in DFU mode or whatever u call it? This might be a way to see if your board is fried or not. Or maybe try another computer?

By DFU i mean the mode you set to upload new firmware to the board. Usually you either put on or take off a jumper.

Tried connecting with another computer and still no luck.
I have searched and can't find anything on the rep rap wiki about DFU mode. A picture of my gen 6 board is attached, could you indicate where I put the jumper?
Also, do you know the meaning of LED1 being constantly lit?
Thanks for your help.

I'm not sure about gen 6 board. All my experience is with my printrboard. Wish I could be of more help.

You might want to try uninstalling the drivers for the board. Worth a try.

YES!
Fixed it.
Unplugged everything from the board and inspected it.
It turns out that one of the pins of the USB connector had been bent, so it wasn't connecting at all.
You can see this in the pic.
I carefully bent the pin back with a flathead screwdriver.
Everything now works.
I am so happy now. Was worried my board had been fried.
Now for a long day of calibration and test printing! grinning smiley
