can you disconnect the hotend thermistor and measure the resistance across the connector with a multimeter? you should get to the terminals on the inside from the back side of the connector. it should read close-ish to 100k most likely.
then (with power off) measure from the vssa pin on the thermistor header on the board and to the Vin ground. (ref wiring diagram) it should be close to 0.
115k on thermistor, VSSA to V-in Gnd 1 ohm
-
that should be all good.
maybe add your config and any config-override file, but given the description not sure its a config issue

Also now when I try to home Y access I get a message saying phase A may be disconnected while it actually runs X motor and not Y.
M667 S1 ; select CoreXY mode
thats kinda relevant i suspect, but i'll defer to the others for config and corexy stuff.
meanwhile, maybe throw in the homeall, homex and homey files

Check your wiring. With CoreXY two motors produce the X and Y motion, not just one. So if only one is moving and it's complaining that there may be phases disconnected, it's probably right. Check you crimps on the motors cables.

Not sure exactly what you mean about checking the wiring they were working fine, no nicks felt wires look the same, none are loose. When I would hit home previous times it would move the Y motor just fine in fact it moved and homed it prior to the print. Now it throws an error and the X motor turns on when I hit home on the Y with no changes in wiring. Crimps look tight, I assumed they would I used proper crimping tool.
Also again Hotbed and Hotend both started reading 2k at same time, and z probe not working. I thought Z-probe was just cheap and I was using z-stop instead so didn't think much of it since I was going to replace with a BL-touch.
Hitting E-stop on webpage should not cause a board to wig out. If it does cause Duet problems why is it there?
-
@Phaedrux I also understand that the X and Y motors produce the movement. If I take the belt off the y motor is does not spin. If I move my z cable to the Y motor it spins. If I use Y cable on X motor it spins. If I plug any motor into Y port it does not spin.
-
It sounds like you've had a failure of the Y driver for sure. Possibly more.
Can you post some close up well lit high res photos of the board? Do you see any areas that look damaged, burnt, etc?
-
@Phaedrux I'll take some pictures just post them here? Nothing looks burned that I can tell, I do know I do not smell any of that lovely ozone of burnt electronics.
-
Yes please post them here, or on an online file sharing folder like dropbox or google drive.

@Phaedrux Hopefully this works

I can't see any obvious signs of burnt chips.
Are you using the nylon washers to isolate the board from the mounting screws?
-
yes I am using nylon washers and stand off posts

@dc42 , does this quality for warranty replacement?

I started a print and the bed did not trip my z stop
What exactly do you mean by this? Was there a head crash? The Y driver not working is one thing, but the thermistor reading 2000 would indicate a possible short.
-
So when I started the print the X, Y, and Z all homed properly. The Z axis moved down and the extruder moved to the center of the bed. What should have happened but didn't is the Z should have moved up which usually trips Z sensor. Instead it sat there like it maybe thought it made the move and then started extruding with the bed not in place. Which is why I tripped the stop.
The Z not moving into position could be my fault since I unplugged z probe since it stopped working, but code is still in there.
There was no bed crash.
-
Also when the Hot end started reading 2l the Bed went to 2k as well.
