Installed Ubis 13s Printer wont connect to PC anymore

[rsloan76]

Hello all.

I've had my Metal Plus since 2015. I've had the same Ubis ceramic hotend for many years. I picked up an Ubis 13s around the time Printrbot went away (figured I better get replacement parts while I still could!)
I decided to install the 13s the other day (for no reason really, the ceramic still worked).
I wired up the hot end cooling fan following the instructions and connected everything else back up. The printer is currently pretty disassembled: Frame parts are off so I can access printrboard. X-axis gantry and extruder are removed, but everything is still wired up and connected.
I went to test that the fan would run, so I plugged in the power (atx ps), plugged in USB cable, and then on my PC: Simplify 3d connection failed. -The hot end cooling fan is on though. Power is getting through, but Simplify wont connect anymore.

What might have happened? I've never had a connection issue ever. Even after several computer reformats over the years. It's always just been: plug in the USB and the power, the go.

Please help. I've been a happily printing on this thing mostly issue-free for the past 4 years!

Did you check to see if WInhoze changed your com port on you? Do you get the connect and disconnect dings when you plug and unplug the cable?

Thanks for replying! After I posted this question, I saw the dates of the "most recent" posts and basically lost hope. Hopefully Brook Drumm is successful in bringing back Printrbot and hopefully that will include support for original products!

Thankfully, I randomly stumbled upon the issue on a Reddit thread. Long story short: the black ground wire for the hotend cooling fan was connected to the wrong pin on the ICSP port on the Printrboard.

How it happened:
I inserted the pin for the black ground wire from the new cooling fan into the molex connector and connected it to the ICSP port. What I didn't realize from the pictures in the instructions is that the 8pin connector is supposed to sit offset so that only 4 pins connect to the 8 pin set on the board.

As soon as I got that sorted, everything connected as normal.

Thanks again for replying Mooselake!

Glad you got it fixed. I don't think I would have been much help on that one.
Just FYI, I try to check in here every day or two for new posts, as does Mooselake.

Glad to hear because I'm having another issue! (I'll make a new post)
