Why does this keep happening
So this has happened twice now. It looks like the print has just shifted over. both times it happened in the same direction, and it did not happen in the same layer on the 2 prints. It is not consecutive prints. I had one mess up, then a good print, then another mess up. all three the same pla, and gcode.

It the Shift on the X-Axis or Y-Axis
Guess it does not matter, It appears the the belt it not quite tight enough and is jumping teeth.
Could be when the drive gear was installed the Allen set screw was not set on the flat key or tight enough and is slipping.

Thanks for the help, but the belts are definitely not loose.

Have you adjusted your stepper motor Vref current

I had checked the level just before the print and it was good. After another print had failed just like this and immediately checked the level and the bed was was off all 4 corners and center where at least a full turn to close to the nozzle. I updated the springs a while back and the wheels are pretty stiff so I?m now sure how they are just turning on there own or if this is the problem as after the print shift it still prints smooth and straight. Just something I noticed

I agree with Roberts, check the stepper voltage. If too low, they can skip steps.

Is there a voltage they should be at? They?re 24v right?

No that is the Supply voltage.
The stepper drivers have an adjustment potentiometer this adjusts the V-Ref for the Drivers.
On my Printers one 12 and one 24V system.
I have on the 12v system
V-Ref on X, Y, E0 and E1 ~ 0.695v
V-Ref on Z ~ 1.395v
I have on the 24v system
V-Ref on X, Y, E0 and E1 ~ 0.395v
V-Ref on Z ~ 0.71v
I do not know what 3D Pinter so I will show you a common video for adjusting 3D Printer V-Ref voltage.

You should search for your 3D Printer to be able the adjust your Stepper Drivers V-Ref voltage.
You should have more than enough information of how to adjust the Stepper Motor Drivers.
Though if you have any questions be sure to ask before proceeding.

Thanks for the info. I?ll look it up. I have the ender 3 btw
Ender 3v2 poor printing quality
