When I home it and click “get position”, it says that X and Y are both -177. I think this is incorrect. I have attached a picture of the wobbly circles. This is done at very slow speeds, 500mm/s (the machine’s max is 5000mm/s). I also used the small metal post to set the correct height. The base of the machine was secured at the time of burning. I don’t know what else I can adjust.
You are correct. It should read 0,0. Can you go to the Console window and enter these commands one at a time and then return results?

I’m also including an image of an PNG I engraved before the disassembly / reassembly, and an after. The “after” is the scattered-looking one. How odd that the better-looking image was the one when the screw was still loose.
Note that this is a fairly old firmware. You don’t need to do it right now while you’re troubleshooting but you probably want to update this firmware when you get an opportunity:

This is the cause of your anxiety. This is setting a work offset which is why your home position is not 0,0. Let’s get rid of it.
Type this into Console:
G10 L2 P1 X0 Y0
Then rerun this in Console to confirm that it took. Please return results.

Thanks so much. I will run the commands in a moment. BTW, how on earth did an offset get applied without my adjusting it? I didn’t even know an offset could be applied until now.

Okay. No error message this time. However, when I home it and click “get position”, it’s still saying X & Y = -177.
This is now the new problem. Let’s try resetting your settings to defaults.
Run in Console:
$RST=*
Then check again:

Okay, it looks like home is finally reading as X&Y = 0. I did a test burn of a perfect circle (see photo), and the shape is still distorted, even with anchoring the device. You can see that the sides of the circle are flattened. It’s also making a strange whining noise that I don’t recognize. Thanks again for your help. I appreciate it. 
I think you’re having an issue with backlash.
Check that the pinion gear on the stepper motors are well secured to the stepper shaft. I suspect they are slipping or loose. There should be 2 grub screws for each pinion. Make sure one is well secured to the flat portion of the shaft. And then firmly tighten the other one.
The issue looks like it’s more likely on the X-axis.
While you are reviewing, make sure that the belt tension is good. The belts should be taught with no slack in the belt… but not stretching.
Then retest.
Thank you. Unfortunately, I don’t understand what those parts are. I have included a photo of my machine, and a link to the video on how to adjust the x-axis. I have removed and reassembled the x-axis before before. Maybe I loosened something during the reassembly. However, I have no idea how to tighten or loosen the belt. It just looks like a continuous band of rubber. Thanks again for all of your help.
First check that the pinion gears are well secured to the shaft as I suspect that’s the primary problem.
As for the belt… I looked a different view and it looks like on the far end of the gantry away from the stepper motors there is another pinion. There may be a bolt underneath that pinion that you can undo and then pull to stretch the belt further. If not there, look for something similar near the steppers that would allow you have movement to increase belt tension.
Thanks. I think I figured it out. Unfortunately, every time I adjust something, something else goes off. I think it may have been damaged from the loose screw. I really appreciate all of your help. I’m now going to contact their returns department.
