Esab Ultrarex UXD-P2000 Upgrade Project

Thanks a bunch mister Tommy. It's been a pleasure working on this machine with you. We are almost there. Corona Virus stuff plus lack of time did halt the project for some time but we are back on track. Z encoder has also been wired and giving output on the linuxcnc software. My friend lost the small LAM usb programmer so I ordered another one. Another friend ordered one at the same time so we now have two usb programmers and a third one hiding somewhere looking at us and waiting for the end of the project to show up
So next step is the LAM motor and the THCAD wiring and we can start cutting the world into pieces
I will put some pics here later. Wiring stuff will also be added for anyone tackling a similar project on a similar machine.
2 years 9 months waaaw !

So the Z motor and drive were wired. But we're having issues jogging the Z motor. When I jog the Z axis I get an error. No idea what is wrong with the configuration.
@Tommy, here is the HAL file and the INI file.
Z motor is this one:

Z Drive is this one:
www.mechapro.de/shop/Stepper-motor-drive...ower-stage::319.html

Wiring:
Mesa to Z dive: GND / AOUT3 => Pin 1 / 2 on the CN4 connector

Z encoder is giving feedback when handled manually in both up and down directions.

Z drive wired to AOUT2. Still the same error.
I will upload pics and pinouts and wiring.

Update:
We changed from the LAM DS3044 driver to a TB6600 and a mesaflash of the 5i25 pins in 5i25_7i77_7i76 mode. X-Y-Z are now working and moving. We have a Z homing issue with the esab home switch. Still working on this with Tommy. Big thanks to Tommy again for his valuable help. We have been bugging him throughout this project
We are noticing one issue with the 7i77: It is drawing 4 amps of current from the PC 5v rail (for the 5v connector). It melted a connector I used to connect my amp meter. I measured the current when I noticed voltage dropping to 4.2v on the PC 5v wiring !! We probably wired something wrong. We will be going over the wiring to see what components are drawing this much power but if any of you guys have any idea you're welcome to share your thoughts.

Will check that. Thanks.
Getting ready for the first cut this weekend, Tommy?
