Motors suddenly sound Horrible

Is this at idle? During movement? Homing?
Can you make a video?
Did you recently update firmware? something must have changed recently? What was the last time it didn't make more noise?

@phaedrux Yes the firmware updated recently. From March 28, the first ever software and firmware setup, to April 4th 2022. In April, I updated from 3.2.x to 3.4.0. However the update, the printer was homing fine at the beginning of using the current RepRapFirmware. Also, recently I added a Z-Probe. Initially it was an inductive probe using a voltage divider to bring the Zstop.in to 0 from around 3. It was G92 Z0, G30 S-1 making sure the trigger height was consistent. Well, was not. So I setup an old endstop switch as a viable replacement. Unfortunately this has not yet been tested because of this fundamental issue of kinematics (STEPPER PROBLEM).
The endstop I now have as the Z-Probe is from the Ender 3's factory package, just without the metal lever. The switch has no electronic influence on the signal in that it simply goes from NO to closed, IF I'm correct.This is a video of homing the x axis from the most recent update of DWC:

Note; the motor does continue to make a slight ticking noise after the loud vibration that sounds until DWC finally reports:
G28 X
Error: Failed to home axes X
After z raises the x-gantry; the loud vibrating sounds for 5sec, the 2nd slight quickly ticking lasts for 1min. These recorded measurements are real-time, the video is edited for time and file size. -
Are you getting any phase disconnected errors in the console? That type of shaking and noise is usually seen when one wire of the motor is disconnected/broken. So check your wiring carefully.
Another test you can do is disconnect the belt from the motor shaft and see if it will spin freely that way. In this case it may be friction or binding preventing the movement. If the printer off are you able to slowly move the print head by hand?

@phaedrux Removed one wire from X connection at board. Home X in DWC. Received this: G28 X
Warning: Driver 0 warning: phase A may be disconnected. The carriage (X stepper, this is an original Ender 3 setup I'm working to get inside an enclosure minded) does try to go down to the endstop but only vibrates fairly rapidly and quite noisily.I did move the X stepper termination from the X stepper to an identical stepper motor and attempt to home. Just to generate some movement, ID the motor or the board... the swapped motor did the same thing, vibration without turning.
When the printer is without power to the drivers (the 24vdc IN) I can move any component freely, gently always. When 24v is flowing through the motors hold their positions.
Did the link to the video work? I had edited it for time however I could produce the long, drawn out, data hog version of whatever. Let me know. This thing may be at the warrantied time frames limitation very soon. Struggling poor person, 200 buck is a TON of money to me.

Update: So, with limited knowledge of driver chips and some confirming knowledge from FPV chips (ESC's) I have deduced that the two phases are in contact of one another on the drivers side. Yes, continuity has been detected and confirmed within drivers 0, 1 & 4. Axis ZA and E0, extruder, seem to be holding their own between their respective phases. I find any sort of explanation a high overstatement. This is something I fail to understand the how, whys, or just about any thing about.

I'm not exactly sure what you mean here. You installed a zprobe and then started having problems?

Be very careful with how you wire and mis-wire the drivers as you're likely to damage them.

Have you tried with new wiring? Do any of the motors and drivers produce proper motion?

I do not recommend you do that. It's like you're trying to short them out or something.

Is it possible you just switched to the latest version of PrusaSlicer? Starting in version 2.4.1 (I think -- I might have been 2.4), by default they send the commands to set the feed rates, accelerations, and jerk. This had me completely confused for a while, as I had just fixed a hardware issue on my printer, so naturally I figured I must have messed something up.
If you have switched recently, go to the printer settings tab, and select Machine Limits in the list on the left. Set "How to apply limits" to "Use for time estimate". That will revert you to the former behavior.

I think this is happening during homing, so before the slicer is involved.

Haven't used PrusaSlicer with this machine yet, have in the past and liked it. However this is happening with a spanky shiny new build; firmware, drivers, board. All is fresh from scratch and RepRap config is at the top execution. Everything is handled though DWC including firmware upgrades and transfers. I do appreciate your thoughts.As for the wiring. the Looms are correct. They are stayed the same as was working before, same motors, setup, all is correct. Man, should the phases hold continuity across the two? Phase 1 (A or B) is in continuity with phase 2 (A or B). So really, any one of the four wires contacts any other three. This is not normal. I think I need to file for an RMA, request requested. Right? Thanks.

Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.
Take extra care on wiring the replacement. Shorting the pins of the drivers are a good way to damage them.
