I could use some help

There’s a Blade Runner inside my printer now.

@fcwilt so I'm rereading this entire thread, because I've been looking for some specific gcode / language, and finally, I found it in your post. I've put some comments seeking clarification in this.
Bit 1: G1 H1 stops when it activates an endstop sensor.
Bit 2: (more important)
M564 H0 S0 allows jogging of the axes even if they are not homed.
Then (after I send that command) you can jog anywhere along the axis regardless of any limits set by M208.
Jog the X axis all the way to the low end. NOTE: on my printer the left end is the low end of the X-axis. The right end is the high end / with NO ENDSTOP. So, if I go to the Low End, I know where the printer / the firmware things 0 is, and when I go to the high end, I know the maximum run.If the idea is to set these two points (for X and Y, and Z?), this process sounds like it will work. I just have to do it correctly?
Execute (send) G92 X0 - this sets the logical position as X=0. NOTE: This gcode /command is telling my config.g file (?) that where the print head is right now is X=0.) (Or, it may be telling my config.g what I want to be the 0 and the maximum run?
Jog the X axis all the way to the high end (the other end, I'm assuming), being careful to not slam into the endstop, just touch it gently. NOTE: on my printer, the high end does not have an end-stop. The end-stop is on the other / low? end.
Read the X axis position off the DWC - you now know the maximum travel of the X axis. NOTE: I hope this isn't reversed? The point is to know the maximum travel?
Do the same for the Y axis.
Now you’re ready to edit your M208 command, pin config.g, to specify the initial values of min/max for both the X and Y axis. NOTE: this sounds like another step I have to do after I've done the above stops.
Reboot / reset the printer, and you will now be able to travel beyond the lints of the X and Y axes; if the axis limits are enabled, which is typically the case. The would be enabled by M564 S1, which I believe is the default state after reboot/reset. HMMMMMM, why would I go to all that trouble to define the boundaries, so I could go beyond them?

@fcwilt so I sent the command, and then I tried to move the print head. All it did was shake side to side, like it was being told to step left step right really fast.
I couldn’t believe what I was seeing. So I tried again. Three times.
Then I tried to move the bed back to its endstop. That worked. The bed moved smoothly. But I couldn’t see the metal piece of the bed that touches the endstop.
So then I looked at the info in DWC. It was a huge number, in the 400’s. I think it was negative. Then I sent the bed to the front of the printer, to see what that number would do, and it started rattling against it, like it wanted to break free.
So I turned the machine off. I spent 12 hours mounting the board under the front of the printer today, where the old board was. And re-routing all of the wiring, and trying to make everything look somewhat presentable.
And it does work worth shite.

I mentioned M564 H0 S0 so you could jog anywhere on any given axis while you determined the max travel for the axis.
The point of the G92 X0 (or Y0) was just to set the current position for that end of the axis to 0 so when you moved to the other end the position displayed by the DWC would directly readout the max travel.
There are other ways to determine the max travel, I was just trying to give you an example of using the DWC and some simply commands to do it.
M564 S1 makes it so you cannot go beyond the boundaries set by M208.
I did not go on to describing how to verify the operation of the endstop sensors and determine their actually position because I did not want to overload you with too much stuff.
I just wanted to be sure we were both on the same page with what I had posted so far.

@fcwilt well, the X-axis is messed up, and the y axis is okay, I guess. But that shaking thing is creep pee!

We can figure that out.

What command are you referring to?
How did you try to move the print head?

@fcwilt I started by entering the command that allows you to move the axis without homing first.
-
@fcwilt and then I used the incremental buttons to move the X axis towards the end stop in the left side of the printer. It’s possible that when I pushed the “move X 10mm left,” the print head went side to side 10 times?

@fcwilt M564 H0 S0

@mac sounds more like a wire is loose on the X axis motor. Check your wiring.

@droftarts after reading through the code, I think you’re right. I did repair the red wire to X, so I’ll check that.

@mac Fixed your Gcode posts. You selected the 'list' format (three dots vertically next to three lines) rather than the 'code' format (like

The symptoms you describe do suggest a stepper wiring issue.
