A Bit of an update.
After getting my mate to spend way to much time on it troubleshooting the problematic Z axis issue, he decided to make the nema 23s just motors instead of integrated steppers. Not long after I had a fully functioning Z axis. The X and Y axes are still the integrated stepper and work well.
Printer is calibrated on the XYZ axes. Tested the extruder side as well all functioning. Only thing really left to do is put the bondtech on it and the usual bed calibrations etc. Then we are off and printing.
Thanks for all the assistance in getting this up and running.
