For some reason I thought I could update code using the DWC.? Put on a new part cooling fan shroud and need to revise my Z offset. Can I send g31 via DWC?

I made the attempt and the console gave me a check mark, but when I ran M503 it still showed the old setting.

Ah, I'm slow, but catching up . . . slowly. So if I make the change in YAT that would put it in memory?

Since I have you, the x and y home to the front left corner. The z probe is homing slightly right of that. Shouldn't it be in the center?

Interesting. Like I said, as Duet's post showed, the l1 makes the sensor function. But when I cycle the power I have to reset the M558. Shouldn't that stay in memory?

Found a post on your site
https://forum.duet3d.com/topic/8963/ezabl-z-probe-wiring-and-configuration/8
TH3D's suggested code is M558 P5 C"!zprobe.in" H3 F900 T1200. When I change the probe type as in the post to l1 for M558 the sensor seems to work fine. However, when I turn off the machine then turn it back on the sensor doesn't work, unless I put the M558 in again.

Thoughts?

Based on your suggestion I changed the value by adding a "1", so 98801. That fixed both the hot end and the bed! Thanks for that! My bad for looking at the image, not the text!

My next issue is setting up for a EZABL. I've looked at the install text from TX3D. At this point I don't want to mess up what has been done, but the printer clearly isn't recognizing the sensor isn't funtioning properly without its code. The instructions say to install config.h (appropriately adjusted) but I don't find a config.h in the sys file. Should I simply add it?

Really appreciate your patience and assistance with all this!!

Yes, stock screen and encoder. I figured out the display and encoder, they function now.
Yes, Reprap 2.05.1. DWC 2.0.4
That's is the instruction set I've been following since the start.

Going through the tests both heaters are showing fault. I double checked the wiring based on the instructions. Suggestions?

Another thing I've noticed is the LCD lights and has info displayed but the knob/button doesn't do anything
