Thanks for all of the information, I will continue to perform the upgrades to get to 3.5.2, I thought the WIFI would have upgraded when I did full fresh install with 3.5.1 but I will also perform that upgrade as well;
As for the extruder, it's now working. I think it might have been a mixture of issues,,, the code error M960 and the tool not being uncommented. I was able to calibrate the extrusion and all seems to be working fine.
Much appreciate the assistance.
