X Axis will not hold the Zero out and stalls when running the quick check from IDC WoodCraft spoil board gcode

Machine Help ❓ Something's Up

Hello all,
Trying to make my spoil board. But when I run the gcode for the cnc system check from IDC WoodCraft I get my X Axis hanging up after it moves from the center that is zero for all axis and makes a loud humming noise. This happened before when I first assembled the CNC and then went away when I ran the break in gcode also from IDC Woodcraft.
5 times I have tried to do the system check and only one time was it able to go through the 19 lines of the gcode. I will include the files and if possible upload a video ( Video file will not upload unsupported file type MP4) Gcode also included. If I can some how get the video to upload you can hear the loud humming and see the cnc continue to step through the rest of the code.

I had a hell of a time getting the X Axis to maintain Zero also at first assemble and first checks with gsender 1.1.4

I re-flashed the firmware via Gsender and also readjusted the backlash bolt for the x axis. I was able to run the gcode for fit check but I now notice that my Z axis tilts forward when the z moves down as it runs through the gcoded steps of the fit check. I will rerun on Monday to verify all items are tightened and set.
