when i press the home icon. The z axis moves downward about 10mm (step size in jog command), and the status changes to alarm, and the machine and work space coords stay the same. (0,0,-3) When i press the home icon without clearing the alarm the same thing happens again Console shows: $h <alarm:8 Ok Grbl 1.1h [$ for help] [MSG:Check Limits] [MSG:$H$X to unlock] s3400<error:9

restore origin works. Set xy sat z works

limit switches work

I have home-upgraded EP2006 CNC for PCB manufacture. When i use GRBL1.1 and non-mechanical (i don't know, i used what i have) limit switches and go home in X0 Y0 i have trouble with movement, because limit switches are enabled.

Try reconfigure your grbl config parameters ($$), i think it will help.

Tried $21=0, rather than $21=1 No change

What does $H < ALARM:8 mean?

Thanks. i checked the limit switches. Xyz have indicator lights on the board. When i activate any of the limit switches the correct light on the board changes to on. That is what is supposed to happen.

So i toggled $5 from 0 to 1 and back. I had the $21=0 Now the homing cycle works But of course the limit switches didn’t work I set $21 back to 1 and now all works

I had increased the pull of from 3 to 5. But until i toggled $5 back and forth that didn’t help

the problem seems to be something in the software somwhere?

hoping it never happens again
