Trying to jog both Z1 and Z2.
Z2 works up and down. Z1 only works going down.
I swapped the Z1 connector the opposite way, Z1 only works going up.
Maybe wiring of the stepper. I swap Z1 stepper with Z2 stepper. Now Z2 stepper only goes in one direction.
Maybe the stepper driver. I swap stepper drivers, same issue.
Maybe Z1 board issue, I utilize the unused “C” stepper driver socket, change the config for Z1 to point to C and works as intended.
Save a copy of the cofiguration using C that seems to work for you.
Go back to the original configuration, and show us what you get for startup messages.

Strange… there is a Z2 message interleaved with the Y/X section of the startup messages.
This leads me to suspect something isn’t correct with the original yaml.
Welcome! 
Please do post your config.yaml file so we can have a look!

I’m reading and following along with your steps toward a process of elimination.
Did I understand correctly that the problem went away completely when you switched from the config.yaml’s Z stepper driver/code for Z1, and instead switched the wiring and the config.yaml code to use the C stepper driver/code for Z1?
If so, then it seems the issue is in the board. Prior to reading “change the config for Z1 to point to C and works as intended” I would have suspected a wiring issue as the main culprit.
Yes, I switched the wiring and config yaml to use C stepper instead of Z1
You’ve done a great job of troubleshooting this and of swapping things around.
config.yaml looks good in both bits you’ve posted.
Based on the steps you’ve noted, it appears to have ruled out a wiring issue.
The one thing I would double check is whether you have extensions in the wiring to the stppers- that there isn’t an intermittent connection in the extension wiring (If you have extensions.)
Otherwise, unless @vicious1 has any other ideas or steps, it does appear that you jackpot has an issue with the DIR connection to the A stepper driver. This could be bad solder work on the headers for the TMC driver, or with the IC that controls direction. Can you post a good hi-res picture of the solder on the A stepper socket headers, and another one of the two ICs just above the capacitor in the A posistion on your jackpot? (U3 is suspect to me)
A+ Customer service from V1 Engineering. Was sent a new board and returned the old board. New board works great, no issues. Easy swap.
I just took the time to look at the board. The Z driver was super hard to insert. Pulled off the header…
The Step and DIR pins were shorted. Bent them into place, all is good, no lost board!!!
This is the second time I have seen a bad header. In the newest version I changed the header company so hopefully this doesn’t happen anymore.
WIN!
That’s what was suspected from the troubleshooting- but we didnt guess it would be the header!
I hope the alternate supplier doesn’t have that issue.
Yeah pretty crazy to see. Really glad it did not pop anything else.
You rock, sir!
I thought about this some more…
With the header contacts shorted like that, the pin on the end almost certainly had to be bent/deformed while it was just a bare part. Which means the assembler who inserted it would have had to bend it back to get it to insert. This is also a manufacturing practices issue. Don’t assemble broken hardware.
