WiFi \ Hard limit error

Hi everyone,

I'm new at both this very forum and as a CNC hobbyist. I have purchased a custom version of Lead 1010 which is as long as model 1515 but wide as 1010. Machine came to with blackbox x32 and I'm using my whole available time to get to know it.

During my learning, tests, configurations I have came into a trouble. I have everything configured and machine works as it should however when I'm adding WiFi config it triggers:

A ALARM: 1 - Hard limit triggered. Machine position is likely lost due to sudden and immediate halt. Re-homing is highly recommended. [ undefined ]

And it loops. I can't home, can't move. Only cancel error message but the alarm stays on.

It seems that either I can have hard limits turned on or WiFi. As soon as I delete settings for SSID and PSK the problem goes away.

I have tried to reset blackbox using reset button with or without USB attached but it does not matter. I tried also changing SSID and PSK on my access point and made it as short as possible without special characters but that didn't helped.

Steps:

1. Machine configured and working properly
2. Adding SSID and PSK
3. Allowing for reboot
4. Manually resetting machine with a button
5. WiFi is working and I'm able to connect
6. Alarm is triggered on both USB and WiFi connection
7. Clearing out SSID and PSK
   
8. Allowing for reboot
9. Manually resetting machine with a button
10. Issue is gone

Will do. Thanks for directions

 

I'm glad that it helped.
