The printer was working ok with the original 1.19 firmware I started with. I updated it because it was no longer supported. So I started a new configuration on the website by starting with an existing configuration. I don't remember making any changes to the end stops. I saw no reason to make changes since everything worked before and I made no changes to the physical printer setup.
This is what the configuration tool showed when I was going through it
Holy crap that fixed it. Thank you so much. I read about that earlier and was going to try it, but haven't got there yet. I can't believe it was this easy.
Thanks again!!
Duet2 Wifi
Cartesian style printer (built by me)
I have updated my printer to Firmware 3.0 and I generated a new config from the config tool website. This printer is one that I built myself and had worked great while on the old firmware 1.19. Now it won't home like it should.
X and Y won't move in the negative direction.
So, "G1 H1 Y-357 F360" doesn't move at all, but "G1 H2 Y5 F6000" moves as expected.
I'm not sure what else to look at and I'm at a loss.

Thanks for the replies. I decided to swap the bed for another one that I have. Now it looks much better. I'm not sure what happened, or why that made a difference, but I'll live with it.
No, I hadn't used hairspray or anything on this bed. I just used blue tape and that was it. Nothing different really. It started doing this after the printer wasn't used for about 2 or 3 months. I'll just leave this other bed on it and go on from here.
Thanks again.
My printer was doing fine, mesh map was great. I hadn't had my printer on for a couple months, and when I started to use it a couple days ago, this is the mesh map that I'm getting.
I can't figure out what's going on with it. I'm using the IR height sensor. Any help would be appreciated.
I feel like you're missing a step in the calibration. I would think your Z offset should be something other than zero. If you are doing all of the steps, then zero should be your nozzle touching the bed.
