So I recently finished installing a new SSD in my computer and had to do a clean install of Windows 7 in the process. Prior to the new SSD, my Printrbot Jr was printing great and everything. Now after I can't get the thing to connect. When I try to connect in Repetier Host, the connect button turns green, but nothing comes up in the log noting that it was connected. It also doesn't register the thermistor reading or anything.

I've tried connecting the RAMPS from my CoreXY build and it connects fine and everything.

I've tried installing Arduino drivers, double-checking ports, changing Baud rate, but nothing seems to work.

Anyone had this problem before?

Not sure if i've had your exact problem, but when I was trying to get things working, I had the older arduino versions as suggested in countless old threads, and trying to connect from XP, wasnt till I switched to 8.1 and got the latest arduino ide that everything started working. so I can only guess that the latest drivers solved my issue, and not being on XP. So maybe win7 doesnt have required drivers or supporting software?

If you have a genuine arduino, download the ftdi drivers, if not, find out what usb to rs232 chip you have on the board and download the appropriate driver. If it's a ftdi clone, either get the driver from the chip maker or use an older ftdi driver v12 or below.

figured it out. I guess apparently the printrboard was registering under 2 different com ports (1 and 4) and I was using the wrong one...
