So finally got around to trying to get the PandaZhu board installed wuth the PandaCAN.
First issue is that the board will not let me connect to wifi until I connect a usb cable and connect to the com port then I can connect to the webserver.
Second issue is that I have loaded the Marlin from the PandaCAN github and wired as per the wiring diagram and connected a thermosistor to see if I can see temp from hotend and see nothing.
3rd issue for some reason I am showing a temp of T:0.00 /0.00 B:24.37 /0.00 @:0 B@:0. I thermosistor is not even connected to the board and shows a temperature. But the yet the PandaCAN board does not show hotend temp.
Ok update. The PandaCAN is now working I had originally swapped wires when I was having the sd card issue or what I thought was the issue. so now as follows are my remaining issues.
#1 I can connect through wireless but as follows. If printer is shut off I turn it on and it will not allow me to connect the first time. If I cycle power off then back on then it allows me to connect to wireless but never on the first power on. It is a strange issue.
#2 Set up the sensorless homing as per the wiki page for x and y axis. But with X and y both set to the same microstepping of 16X one axis moves faster than the other. If I change the firmware back to non sensorless and no uart with the jumpers back to as delivered on MS1 and MS2 then the steppers move at the same speed. I tried this in Cartesian and CoreYX. So with uart enabled and jumpers and firmware set to wiki y axis moves slower than x.
Update. If I swap Address 0 to Y and 1 to X then Y moves correctly but not X.
