Voron 2.4 R2 LDO Kit

Everything is moving so win. I am able to home and it seems correct. moves right until end switch then back until endswitch then center of bed where Z (Voron Tap) homes. This works fine. When I try to level the gantry it takes off probes near front left then back left, then seems to travel all the way back and probes then takes off toward the front to about mid plate then dives left hard. Never seems to stop when headed left. Crashes into left side then gives a probe trigger error.
I dont get it, it does not seem to be probing in the locations I have seen after watching like 500 videos. Never competes gantry level. Then it seems to have max and 0,0 off
Seems off after homing when I try to send it to 0,0 it is never in the front left corner of the bed where I would expect it to be. I thank you for the help!

Are you able to post a video on YouTube? It’s hard to understand what’s happening based on a description. I just finished upgrading my 2.4 with Tap, and nothing in your config is jumping out at me as a problem.
Looks like the bed dimensions become halved.
Either the microsteps doubled for what ever reason during the QGL or massive steps had been missed.
I did not play the video with sound so maybe there are some apparent issues but it looks like that the gantry drives way too much backwards colliding with the Z cable chain.
Maybe this causes the missing steps for X and Y directions.
What happens if you manually drive the gantry across the bed maybe mimicking the QGL movements?
That terrible noise is either the motors skipping steps, or the shaft of the motor spinning inside the pulley because the set screw is loose. It’s making those noises even during homing, so you have some physical issue with the printer.
I would remove the belts and inspect the pulleys. Also make sure you have no binding, and the gantry moves freely all the way to the limits of each axis.
Turned out to be a bad steeper motor. Replaced B motor and runs smooth a silk. Thanks!
