Here is the config file for the stepper motors

Hi, my duet2 wifi board is having issues with the stepper motor for extrusion. When I hit retract, it will extrude and when I hit retract it again, it will do the opposite and extrude. Extrude button is not working at all, and when I hit it the motor makes a humming/hissing sound but does not spin. I've already changed out the stepper cable motor and even ordered a new duet 2 wifi board which did not fix the issue.

@gloomyandy and @elmoret Thank you! I will change the config.g file and see if that fixes the problem.

@elmoret Here is a diagnostic report I performed as well.

Here is my config file as well

I just received a Duet2 wifi board with external antenna a few days ago. I was able to set up my network and password and connect via DWC. However, i was having issues with my stepper motor for extrusion where I would hit retract and it would extrude and then retract after hitting the button a second time. Someone recommended that I delete my config files and upload new ones to see if this would fix the issue. However, after doing this my computer will no longer connect to the wifi of the printer. I can connect to the board via USB and set a network access point there, but when I disconnect the USB after turning on the access point, the network of the printer never shows up.
