Well, it is looking like a bad TC PCB. I'd forgotten that I had a thermocouple reader for my multimeter so I hooked it up and the TC worked perfectly. I reflowed all the solder joints on the PCB with my soldering iron and it still reads a constant 93 degrees. The LED lights up just find so I'm guessing the problem lies in the amplifier chip.
I'll be contacting UM Support about a replacement this week. Thanks for the help!
If you want to give it a shot yourself, there have been cases of a lifted GND pin on the AD597 chip, so you could try re-soldering that one. Should be doable with most soldering irons.
Hello! I just finished assembling today, and start with the software setup, i'm stuck on the exact trouble that Mcastor is. Any solutions?????
Hello. I have the exact same problem, you managed to solve the problem?
Anyone have sugestions to solve this.

First check if all cables are properly connected. And if the 3 wire connector is wired up correctly. There have been a few cases of the 3 wire connector being wired wrong, check if the colors (red/black/yellow) is in the same order on both sides. You could also swap it with the other color 3 wire connector.
Had the same problem. Two wires were swaped the wrong way on the connector that goes to the tiny amp board on top of the print head. The wires that plug into the amp board with the white connector that has the black dot on it are the ones I am talking about. When you look at the white connector at the end of the wire with the black dot facing you and with it pluged in. The yellow wire should be on the left. The red wire in the middle and the black wire on the right. That fixed the problem with reading 93C all the time.
Another problem I had was with the tempeture readings going up or down giving a temp ERR. This turned out to be a bad solder connection on the amp board. One of the leads on the green screw terminal connector was not soldered to the board good enough. I just had to touch up the solder joint and it works perfect now.
Good troubleshooting work, Bret4!
Speaking of a TC-board?
Always having trouble where to place my questions on the forum :shock:...
Somebody knows why the boards are placed on the printhead, other than cosmetic blue led reasons.
To keep the printhead more compact I was thinking of moving them underneath the machine.
Any electronic/magnetic/Interference reason why I should not?

Sounds like a bad TC board. You can visually check if there is a soldering error, also check if the blue light goes on, and you can contact UM support for a replacement.
