Got it all sorted, thank you for the link.

I am having an issue withe the Z motor continuing to lower the extruder even after the homing switch is triggered. The X and Y axes home properly and stop as they should.
I have them all set as active low and in the web interface It even shows the endstop is active when triggered. It just continues to move down anyway. I'm sure I have the correct one connected as I activated all three just to be sure. Has anyone else had this issue?

I just updated the firmware 1.21RC2 and the WiFi update using commands M997 S1 and M997 S0.

I then ran M552 S0 which gave me the response of ok <lf>I then input my SSID and password
I then sent M552 S1 and got this:
Turn off the current WiFi mode before selecting a new one<lf>ok <lf>Then I ran M552 and got the same as I was getting before:
WiFi module is being started

Next I removed the SD card and opened the sys folder and inserted a semicolon in front of M552.
I place it back into the SD slot and when I go through the procedure again to enable the wifi, enter the SSID, password and send M552 S1 again I get this:
Turn off the current WiFi mode before selecting a new one

Nothing is connected to the board and never has been, it just got it a few weeks ago and haven't been able to get it to work.</lf></lf></lf>

After downloading and reloading the firmware several times and even replacing the wifi module with a new one I had in the parts bin I still get the same response. Any ideas would be much appreciated? I'd prefer not to have to buy another board.

Got it mixed up with M122.

I'm getting this now when use the M552 command
M552
WiFi module is being started
ok

I am thinking it is supposed to start at some point.

When I type M112 I get this:
Emergency Stop! Reset the controller to continue.ok
I then use M552 S-1 to stop it, but when I re-enable it and use M112 again I get the same message.
I have tried powering it externally as well, but it makes no difference.

Hello,

I have been working on getting the wifi module working for several hours. I am using the latest firmware on GitHub. When I ype M552 S0 using YAT It only says "ok" . I then use the M587 command, input my username and password and I get this:
M587: Failed to add SSID to remembered list<lf>ok <lf>When I upload the firmware to the WiFi module it seems to work, but gives me an error. about bytes per line exceeded. Any ideas? Below is the diagnostic report.
