Homing Issue GRBL Alarm 8 HELP!

Hi All,

I am re-posting the email sent to the support team. I have had limited response so I am looking here if anyone can help me please.

Thank you!

Hi,

I just moved and had to reset up my PRO 5. All looks good and I ran the setup again but, now I am getting this Alarm 8 code.

The red light is on in the 2nd picture.

It looks like the Y axis is not moving back far enough to trigger the Homing switches. You can see this in the video.

I did all the testing as per the video and web page you sent me links to. Could you please call me about this issue. Also did the homing switch test with a metal strip and all the red LED’s lit.

Also re-downloaded the latest update of the software. Machine only has 59 hours on it and it ran perfectly everytime before this.

Would you please help me with this issue and call me, I am still having the same issue after rechecking everything. I have sent 3 emails to you asking for help.

AN UPDATE:

Tech Support called me today and we ran over all the items that could be causing the issue with the Homing and Alarm 8 code.

The fix … the coupling on the X-axis was slipping. After re-tightening the setscrew it worked as new again. I also recheck all the other ones just to be sure.

So, If you are getting the same error code as I did, it may be a simple fix as a ball-screw coupling slipping as I had. Just tighten the 3mm clamp screw/s. See picture.

Thank you Tech Support, your the best!
