Figured it out.
I believe the PT100 wire gauge was too small to make a good contact in the connector.
It was good enough for resistance reading but not when things were powered up.
I seperated out the PT100 wires out and used a smaller JST plug and it's all working now.
Thanks for the patience.
@calvinx Welcome to today's world.
I'll just leave it there.
Just thought I would post to wrap up my problem and incase anyone else runs into the same issue.

It's been a few months since we used the printer. Not sure what is happening.
Firmware 1.21 w/ IR probe
I've gone through the IR calibration. Heated everything up, brought the hot end down until it just grabs a piece of paper- set the Z height G92 Z0, then backed off 5mm and probed with G30 S-1 at entered that in the config file.
I have measured and remeasure the home height, even used the control panel to raise the hotend until it touched the stops to confirm my measurement.
Anyway, even after all that is done, if I manually bring the hotend back down until it just grabs the paper again, the Z height reads at around 85mm.
I just don't see what I'm missing.

I'm sorry I missed that, I used the reprap config tool for the Config.g file and wasn't even paying attention to the probe type in the command line.
I've run through the steps here: https://miscsolutions.wordpress.com/mini-height-sensor-board/
I've had this working before, but from another post I've had to start everything over from the beginning.
I've verified my Z height in the config.g by bringing the hot end down until it just just starts to get resistance with a piece of paper- the Z position reads zero. Yes while at temp.
When I send the command to probe in the instructions above it stops.
It's when I send the auto-calibrate command that it crashes. I can see the LED trigger, but it just keeps going.
I've verified that right before the LED comes on I have a reading of 466 and then when it triggers it's 533.

Just thought I would post to wrap up my problem and incase anyone else runs into the same issue.
I was using a Makerhive Yellow Jacket Quick Clip.
It seems like the gauge of the PT100 wires was too small. It made just enough contact for the resistance measurements, but failed when powered up.
When I routed the PT100 using a seperate JST plug, it all works correctly now.
@calvinx Welcome to today's world.

@dc42 I'll try. I am using a Yellow Jacket quick clip so it makes it hard to get a good picture at the hotend side.
I had the single wires from the PT100 going into the bottomside and then the 4 wires from the top.
I am going to eliminate that and directly wire everything and see if that works. Just guessing at this point is the Thermistor worked before with the connector
@danal I understand. My point is every single test individually is correct. Yet put it all together and it doesn't work.
That is where I'm puzzled. That PT100 has the same resistance as the one in the hotend measured at the board.
The only thing I can think of is perhaps the voltage isn't high enough? Waiting for David to take a look at the post since I can't find anywhere that lists what the voltage should be.
@dc42 I have- you tried to help in another thread- all test are fine yet it still doesn't work- it why I walked away from the printer for a few months.
It's wired correctly using two cat5 pairs that are twisted and run in separate tower with no other wires.
At the board:
pins:
1-4 104 ohms
2-3 104 ohms
1-4 .009 volts
2-3 .009 volts
not shorts to out case of PT100. I have two PT100, both behave the same.
Config file has the M305 P1 X200.
Also behaves the same on either channel.
I've googled and read through just about every thread I've found from others with the same issue.
With 100 ohm resistor in pin 2-3 jumpers 1-2 3-4 I get -1.4 degrees.
With one of the PT100s wired in place of the resistor 22 degrees.
So what's left me baffled is where is the problem in the wiring from the board to the PT100 in the heater block when all the measurements check out.
That was it, thanks for all the help
Now to start over with the PT100 always reading 2000
