Could you post your config.g here, please?

What type of thermistor are you using?
-
Not certain. It came with the V6 hotend I ordered from AliExpress, so it's a fine piece of quality Chinese craftsmanship, I'm sure...
-
Could you measure the resistance of the hotend thermistor at room temperature, please?
-
How do you do that?
-
With a multimeter.
-
My multimeter has crapped out on me, so I did the next best thing and plugged a spare thermistor into the Duet2 and turned the printer on. The temp was reading 24 degrees, so I'm taking that as a bad thermistor. Working to change that out now.
-
Thermistor has been changed out with a known working one and now that it's hooked up through the Smart Effector, it's not registering a correct temp.
When I plugged the replacement thermistor into the board, I got a reading of 24 degrees or so. Now that it's wired back up to the Smart Effector, I'm getting over 9k degrees again.
-
I've now ran a new cable from the board to the 8-pin connector and the Thermistor still isn't reading.
Since I was able to get a reading when I plugged the Thermistor directly into the board, but can't once it's routed through the Smart Effector, is it safe to assume the point of failure is somewhere on one of the PCB connections?
I know nothing about soldering connections to a PCB, so I really wouldn't know by looking if there was something missing/wrong on that end.
-
Please post photos of all connections.

Tried posting the images directly, but they errored out. Hope that's enough angles.

@beanman1
Thermistor cabling is wrong on the effector 4th cable from the left looking at the connector needs to go in the second from the left -
@beanman1 your thermistor wires are going to the wrong pins on the eight way connector on the effector if you say they are now connected to pins 3 and 4 they need to be in pins 2 and 3.

The wiring diagram said T1&2 were paired, so I assumed that meant those were for T0. Guess I was wrong.
Made the change so it's now 1 empty, the 2 thermistor wires, 1 empty, the Z Probe connections.
Turned it on and the Thermistor is now reading 2k instead of over 9k...
-
Disregard... the connection to the board had came loose. That's fixed and the Thermistor is now reading correctly.
Now to figure out why the carriage is crashing into the bed during Auto Calibration...
Thank you for all the help and information!

When it referred to t1 and t2 it means that the left 2 wires are common on the underside of the effector and the T2 is pins 3 and 4 the reason is so that you can use a PT100 but convert it to 4 wire mode.

@Dougal1957 oh, ok. Thanks for the info.

If someone would be so kind, please mark this issue as Solved.
Just another n00b that made a mistake.
